If you want more reliable heart rate data during exercise than you typically get from the wrist, there are two main ways to go: a chest strap or an optical armband. Chest straps remain the obvious choice if accuracy comes first, while armbands are easier to put on and generally more comfortable if you do not like having something wrapped around your chest.

Why use a dedicated heart rate monitor?

For everyday tracking, the heart rate sensor on a smartwatch is usually good enough. Things get a bit more demanding once you start using heart rate to control a workout, particularly during intervals, harder runs or sessions where you are trying to stay inside a specific training zone.

That is where a dedicated monitor still makes sense. Chest straps generally react more quickly when your heart rate rises or falls, while armbands can offer a nice middle ground if you want something more comfortable. If you use heart rate zones regularly, the cleaner data can make it easier to judge effort rather than relying entirely on pace or how you happen to feel that day.

Heart rate zones themselves are useful for different types of training. Easier zones are typically used for aerobic and endurance work, while the higher zones come into play during threshold sessions and harder intervals.

Chest strap vs armband vs wrist

The three approaches measure heart rate in slightly different ways. Most chest straps detect the electrical activity produced by the heart with electrodes sitting against the skin. It is essentially a simplified version of the principle used by an ECG, which is why chest straps tend to respond particularly well when intensity changes quickly.

Armbands usually use optical PPG sensing, much like a smartwatch. The difference is where the sensor sits. Moving it higher up the arm can reduce some of the movement and fit issues you get at the wrist, while also making the device much easier to wear than a chest strap for some people.

Smartwatches and fitness trackers are the most convenient option because you are probably already wearing one. They shine light into the skin and analyse changes in blood flow to estimate your pulse. Modern sensors have become very good, particularly during steady exercise, but movement, fit, cold weather and rapid changes in effort can still cause problems.

That is why there is no single best format for everyone. A chest strap still makes the most sense if accuracy is the priority. An armband is a good compromise if comfort matters more, while a wrist sensor is easily the most convenient for everyday use.

How much more accurate is a chest strap?

There is plenty of research showing why chest straps became the reference point for exercise heart rate tracking. One Cleveland Clinic study compared several wrist-based monitors with a Polar H7 chest strap and a three-lead ECG while participants ran on a treadmill.

The chest strap produced the closest agreement with the ECG throughout the test. The Polar H7 recorded a correlation coefficient of 0.98, while the Apple Watch Series 3 came next at 0.96. The other wrist devices tested were lower at around 0.89.

The gap also tended to increase as running speed went up. At rest and during easier activity, the difference between wrist and chest measurements was much smaller. Once participants were working harder, the limitations of optical wrist sensing became more noticeable.

It is worth putting those results into context. The study used devices that are now several generations old, and wrist-based heart rate sensing has improved considerably since then. It also took place on a treadmill rather than outdoors, so it does not perfectly reproduce real-world running.

The broader point still holds, though. Wrist sensors can work very well during steady exercise, but chest straps remain the safer bet when you care about rapid changes in heart rate. That matters most for intervals, threshold work, racing and other sessions where a delayed or incorrect reading can throw off the entire workout.

Armbands sit somewhere between the two. They still rely on optical sensing, so they do not have the same inherent advantage as an electrical chest strap. But moving the sensor away from the wrist often gives it a cleaner signal, while keeping the setup more comfortable and easier to put on.

Best heart rate monitor chest straps

Polar H10

Polar H10

Buy on Amazon

Battery:

Up to 400 hours, replaceable CR2025

Heart rate technology:

Electrical chest sensor

GPS:

None

Connectivity:

Bluetooth LE, ANT+ and 5 kHz GymLink

Water resistance:

WR30

The Polar H10 has been around for a long time now, but there is a reason it is still one of the easiest chest straps to recommend. We reviewed the H10 back when it launched and found it comfortable, accurate and very reliable, and not much has changed on that front.

The soft fabric strap uses silicone dots to stop it moving around during exercise, while the sensor itself can connect to two Bluetooth devices at the same time. ANT+ and Polar’s 5 kHz GymLink transmission are also supported, so it works with a wide range of watches, cycling computers, gym equipment and training apps.

There is onboard memory as well, although it only stores one training session at a time. That is handy if you want to train without carrying your phone, and the H10 is also water resistant to 30 metres for swimming. With up to 400 hours from a replaceable CR2025 battery, charging is something you simply do not have to think about.

It is not the newest heart rate monitor in this guide, nor does it try to throw a long list of extra training metrics at you. What it does very well is deliver dependable heart rate data with excellent compatibility, which is why the H10 remains such a strong all-round choice.

Pros

+ Excellent heart rate accuracy

+ Comfortable, non-slip strap

+ Bluetooth, ANT+ and GymLink support

+ Very long battery life

Cons

− Internal memory limited to one training session

− Few extras compared with newer premium chest straps

Wahoo TRACKR HEART RATE

Wahoo TRACKR HEART RATE

Buy on Amazon

Battery:

Over 100 hours, rechargeable lithium-ion

Heart rate technology:

Electrical ECG chest sensor

GPS:

None

Connectivity:

ANT+ and up to three simultaneous Bluetooth connections

Water resistance:

IPX7

Wahoo TRACKR HEART RATE replaces the old TICKR generation with a much simpler proposition. It is still a straightforward chest strap built around accurate heart rate tracking, but Wahoo has finally moved away from the replaceable coin cell and given it a rechargeable battery.

Battery life is rated at more than 100 active hours, so this is not something you should find yourself charging particularly often. The sensor uses electrical heart rate measurement and can also provide HRV data to compatible apps. There is ANT+ support as well as up to three simultaneous Bluetooth connections, which makes it particularly handy if you train with several devices at once.

Comfort is another area Wahoo has focused on. The strap is slim and soft, while the pod sits fairly flat against the chest. There are also LED indicators that let you quickly check battery and connection status before starting a workout, which is a small thing but genuinely useful when you are trying to get out of the door.

The trade-off is that TRACKR keeps things pretty basic. There is no onboard workout memory, no running dynamics and no attempt to turn it into an all-purpose training sensor. But if what you want is an accurate, rechargeable chest strap that can talk to several devices at the same time, that simplicity is part of the appeal.

Pros

+ Accurate ECG-based heart rate tracking

+ Rechargeable battery with over 100 hours of use

+ ANT+ and three simultaneous Bluetooth connections

+ Comfortable, low-profile strap

Cons

− No onboard workout memory

− No advanced running dynamics

− Not designed for recording swim heart rate

Myzone Switch 2.0

Myzone Switch 2.0

Buy from Amazon

Battery:

3 to 6 months between charges

Heart rate technology:

ECG on chest, optical PPG on arm or wrist

GPS:

None

Connectivity:

Bluetooth 4.0 and ANT+

Water resistance:

Waterproof to 10 metres

Myzone Switch 2.0 takes one of the more unusual heart rate monitors around and gives it a fairly substantial refresh. The big idea has not changed. You can wear the same sensor on your chest, arm or wrist, which means you are not stuck with a chest strap every time you want to track a workout.

How it measures heart rate depends on where you put it. On the chest it uses an ECG sensor, with Myzone quoting 99.4% accuracy. Move it to the arm or wrist and it switches to optical PPG, where the company quotes 95%. That flexibility is the real reason to choose it over a conventional chest strap. You can use ECG for harder sessions where accuracy matters most, then move it to the arm or wrist when comfort is more important.

Switch 2.0 also improves quite a few things from the original MZ-Switch. The sensor has upgraded hardware, a larger LED display and redesigned straps, while battery life is now rated at between three and six months depending on use. There is also up to 36 hours of onboard workout storage, so you do not need to keep your phone nearby.

Connectivity is good too, with both Bluetooth and ANT+ for linking to gym equipment, cycling computers and compatible apps. It can also track swimming when worn on the wrist and is waterproof to 10 metres. The downside is that you are paying quite a bit more than you would for a straightforward chest strap, but few alternatives give you this much freedom over how and where you wear the sensor.

Pros

+ Can be worn on the chest, arm or wrist

+ ECG measurement when worn on the chest

+ Up to 36 hours of onboard workout storage

+ Bluetooth and ANT+ support

+ Much longer battery life than the original Switch

Cons

− More expensive than a conventional chest strap

− Optical accuracy is lower when worn on the arm or wrist

− Arm strap is sold separately

Garmin HRM 600

Garmin HRM 600

Buy from Garmin

Battery:

Up to 2 months at 1 hour per day, rechargeable

Heart rate technology:

Electrical ECG chest sensor

GPS:

None

Connectivity:

Bluetooth and ANT+

Water resistance:

5 ATM

Garmin HRM 600 is the one to look at if you already train with a Garmin watch and want more than basic heart rate data. It sits at the top of Garmin’s current heart rate monitor range, combining an ECG chest sensor with running dynamics, standalone workout recording and swimming support.

Pair it with a compatible Garmin watch and it can add metrics such as stride length, vertical oscillation, ground contact time balance and step speed loss. The latter also feeds into newer features such as Garmin’s Running Economy metric. It can also provide pace and distance during indoor track and treadmill sessions, which makes it quite a bit more useful than a chest strap that simply sends across your heart rate.

The HRM 600 can record an activity even when you are not wearing a watch and sync the session directly to Garmin Connect afterwards. That also comes in handy for swimming, where it can store heart rate data underwater and pass it back to a compatible Garmin watch once the session is finished.

Garmin has also switched to a rechargeable battery this time around. Battery life is rated at up to two months if you use it for around an hour per day, and the sensor module can be removed so the strap itself can go in the washing machine. It is one of the more capable chest straps here, but a lot of that extra capability makes the most sense if you are already firmly inside the Garmin ecosystem.

Pros

+ Accurate ECG-based heart rate and HRV tracking

+ Advanced running dynamics with compatible Garmin watches

+ Can record workouts without a watch

+ Good swimming support and 5 ATM water resistance

+ Rechargeable battery and machine-washable strap

Cons

− Expensive compared with simpler chest straps

− Many advanced features require a compatible Garmin watch

− Battery life is shorter than coin-cell chest straps

Suunto Smart Heart Rate Belt 2

Suunto Smart Heart Rate Belt 2

Buy from Suunto

Battery:

Up to around 460 hours, replaceable CR2032

Heart rate technology:

Electrical ECG chest sensor

GPS:

None

Connectivity:

Bluetooth 5.4, up to three simultaneous connections

Water resistance:

30 metres

Suunto Smart Heart Rate Belt 2 is a much bigger update than the name suggests. It still handles the basics you would expect from a chest strap, including accurate heart rate and beat-to-beat R-R data, but Suunto has also packed in motion sensors, onboard memory and support for several devices at once.

The six-axis motion sensor is the standout addition. Pair the belt with a compatible Suunto watch and it can measure running metrics including cadence, ground contact time, vertical oscillation, flight time and left-to-right ground contact balance. That puts it much closer to Garmin HRM 600 territory than the simpler chest straps in this guide.

It can also store up to 20 hours of heart rate and R-R data when your watch is out of Bluetooth range. That is useful for swimming, team sports and other workouts where wearing a watch is awkward or not practical. The R-R data is also important for Suunto ZoneSense, which uses beat-to-beat information to assess exercise intensity.

Battery life is another big strength. Suunto quotes around 460 hours from a replaceable CR2032 cell with power saving enabled and running-form tracking switched off. It can also maintain three Bluetooth connections at the same time, although there is no ANT+ support, which is worth keeping in mind if you have older gym equipment or cycling gear that relies on it.

Pros

+ Accurate heart rate and R-R interval tracking

+ Detailed running-form metrics with compatible Suunto watches

+ Up to 20 hours of onboard heart rate and R-R memory

+ Very long replaceable-battery life

+ Three simultaneous Bluetooth connections

Cons

− No ANT+ support

− Running-form features require a compatible Suunto watch

− Onboard memory features are mainly aimed at Suunto users

Frontier X2 and Frontier Zone

Frontier X2 and Frontier Zone

View on Frontier’s website

Battery:

Zone up to 30 days typical use; X2 around 14 days

Heart rate technology:

Continuous single-lead ECG chest sensor

GPS:

None, uses connected phone or watch

Connectivity:

Bluetooth, one phone plus two external devices

Water resistance:

IP67

Frontier X2 and Frontier Zone are quite different from the other chest straps in this guide. Heart rate is only part of what they do. Both continuously record a single-lead ECG during exercise and use that signal to produce additional data such as HRV, breathing rate, Cardiac Strain, Training Load and Body Shock.

We have spent plenty of time with both. In our Frontier X2 review, one of the main strengths was the amount of physiological data available beyond heart rate. The newer Frontier Zone keeps that basic idea but simplifies the hardware, removes the small display, switches to USB-C and stretches typical battery life from around 14 days to as much as 30 days.

Both can work independently and save a workout to onboard memory, or broadcast heart rate over Bluetooth to compatible watches, cycling computers and training equipment. You can connect a phone plus two external devices at the same time. There is no ANT+, though, which makes them less flexible than Polar, Garmin and some of the other straps here if you still use ANT+-only equipment.

The Zone is the one we would lean towards now. Battery life is considerably better, the screen on the X2 never added much in practice, and the vibration alerts are genuinely useful for staying inside a training zone without constantly looking at a watch. There is a catch, though. Some features that came as standard with the X2, including live ECG streaming, ECG exports and Garmin Connect integration, now require Frontier Premium on the Zone.

These are also overkill if you simply want accurate heart rate during exercise. Their real appeal is the ability to record ECG continuously while you train and dig much further into what was happening during a session afterwards. They are health and fitness devices rather than replacements for clinical ECG equipment, but they offer a type of data you simply do not get from an ordinary heart rate strap.

Pros

+ Continuous ECG recording during exercise

+ Much deeper heart and training data than a normal chest strap

+ Can record workouts without a phone or watch

+ Useful vibration alerts for heart rate and training zones

+ Frontier Zone has much improved battery life and USB-C charging

Cons

− No ANT+ support

− Several Zone features require Frontier Premium

− More than most people need for basic heart rate tracking

Wellue VisualBeat Strap-Free HRM

Wellue VisualBeat Strap-Free HRM

Buy from Wellue (use code GW10 for 10% off)

Battery:

Up to 48 hours, rechargeable

Heart rate technology:

Electrical chest sensor

GPS:

None

Connectivity:

Bluetooth 5.0 and ANT+

Water resistance:

IP22

The Wellue VisualBeat is the odd one out here, and that is exactly why it earns a place in the guide. As we found in our hands-on review of the VisualBeat, you can wear it with a conventional chest strap or ditch the strap altogether and attach the sensor directly to your chest using disposable ECG electrode patches.

It still uses electrical heart rate sensing in either setup, so going strap-free does not mean switching to optical PPG. In our testing, the numbers were very close to a Garmin watch paired with a Polar heart rate monitor over a 15km run, and the same pattern continued across other workouts. The patches were also noticeably less obtrusive than wearing a band around the chest.

There is quite a bit packed into the sensor too. It has Bluetooth and ANT+, can record without your phone, and stores up to 10 sessions or 30 hours of data in total. The ViHealth app gives you live heart rate and ECG, while configurable vibration alerts can warn you when you move above or below your chosen heart rate thresholds.

The strap-free setup does have limitations. We found that the adhesive patches can start to come loose during particularly sweaty or intense workouts, in which case the regular chest strap is the safer choice. IP22 protection also means this is not a monitor for swimming. But if you dislike wearing a traditional chest strap and still want electrical heart rate sensing, the VisualBeat offers something genuinely different from the rest of this list.

Pros

+ Can be worn with a chest strap or adhesive patches

+ Accurate electrical heart rate sensing

+ Bluetooth and ANT+ support

+ Onboard memory for phone-free workouts

+ Customisable heart rate vibration alerts

Cons

− Adhesive patches can loosen during sweaty workouts

− Disposable patches need replacing

− IP22 protection means it cannot be used for swimming

Best heart rate monitor armbands

Polar Verity Sense

Polar Verity Sense

Buy from Polar

Battery:

Up to 30 hours, rechargeable

Heart rate technology:

Optical PPG sensor

GPS:

None

Connectivity:

Dual Bluetooth LE and ANT+

Water resistance:

WR50

Polar Verity Sense is the armband we would put at the top of the list right now. We covered the Verity Sense when it first arrived, and the basic idea still works very well. Instead of wrapping a sensor around your chest, it sits on your upper or lower arm and measures heart rate optically.

Comfort is the big attraction. The sensor itself weighs just 5 grams and the complete setup comes in at 19 grams, so it is easy to forget about once you start training. Moving the optical sensor away from the wrist also helps avoid some of the fit and movement problems you get with watches, although it is still an optical sensor and can lag behind an ECG chest strap when heart rate changes very quickly.

Polar has packed in plenty of useful extras as well. Battery life is now rated at up to 30 hours, while the 16MB of internal memory can store as much as 600 hours of training. You can record a workout without carrying your phone, or broadcast heart rate live using ANT+ and two simultaneous Bluetooth connections. Bluetooth range stretches to as much as 150 metres with the sensor in its holder.

Swimming is another area where the Verity Sense stands out. It comes with a clip that attaches the sensor to your swimming goggles, placing it against the temple rather than the arm. In swimming mode it can record heart rate as well as pool metrics, and WR50 water resistance means it is built for regular use in the water. If you want something more comfortable than a chest strap without giving up serious training features, this is probably the most complete armband option here.

Pros

+ Very comfortable and lightweight

+ Up to 600 hours of onboard workout storage

+ Dual Bluetooth and ANT+ support

+ Excellent option for swimming

+ Strong 30-hour battery life

Cons

− Optical sensing can lag during rapid heart rate changes

− Not as accurate as an ECG chest strap in every type of workout

− Proprietary charging cradle

Scosche RHYTHM24

Buy from Scosche

Battery:

Up to 24 hours, rechargeable

Heart rate technology:

Optical PPG sensor

GPS:

None

Connectivity:

Bluetooth LE and ANT+

Water resistance:

IP68

Scosche RHYTHM24 has been around for a while, but it still has a few tricks that most optical armbands do not. In our RHYTHM24 review, we found it comfortable, easy to wear and remarkably close to a Polar H10 chest strap during running.

It uses a combination of green and yellow optical sensors and can be worn on either the upper or lower arm. Once the strap is adjusted properly it stays in place well, and for anyone who dislikes having something wrapped around the chest, it is a much less intrusive way of getting heart rate data.

Where RHYTHM24 still stands out is the feature set. There are separate running, cycling, swimming, heart rate and HRV modes, along with duathlon and triathlon modes. It also has up to 13 hours of onboard memory, so you can train without carrying a phone or watch and upload the workout afterwards.

Battery life is rated at up to 24 hours and connectivity covers both Bluetooth LE and ANT+. IP68 water resistance also means it can be used for swimming, although heart rate is recorded to the device rather than transmitted live through the water. The hardware remains capable, but the software side has never been its strongest point. In our testing, the Rhythm Sync app felt much more basic than the hardware deserved.

Pros

+ Very good optical heart rate accuracy

+ Comfortable upper or lower arm fit

+ Up to 13 hours of onboard workout storage

+ Bluetooth and ANT+ support

+ Multiple sport modes including swimming and triathlon

Cons

− Rhythm Sync app is fairly basic

− Swim heart rate is recorded rather than transmitted live

− Older design than the Polar Verity Sense

Heart rate technology:

Optical PPG sensor

GPS:

Connectivity:

Bluetooth and ANT+

Water resistance:

IPX7

Wahoo TICKR FIT keeps things much simpler than the other two armbands in this guide. There is no onboard memory, swimming mode or long list of extra metrics. You put it on your arm, pair it with your watch, bike computer or phone and use it as an external heart rate sensor.

It uses an optical sensor and can be worn on the forearm or upper arm, with small and large straps supplied in the box. The whole setup weighs just under 20 grams, so it is easy to forget about during a workout. Wahoo also includes LED indicators that confirm when the sensor is switched on and connected.

Connectivity covers both Bluetooth and ANT+, although Bluetooth is limited to a single connection. Battery life is a strong point at up to 30 hours per charge, which actually puts it slightly ahead of both the Polar Verity Sense and Scosche RHYTHM24 on paper.

We have also compared TICKR FIT with competing optical armbands in our Polar OH1+ review. The appeal remains much the same today. It is comfortable, straightforward and widely compatible, but it lacks the onboard recording and swimming features you get from Polar and Scosche. If all you want is an optical heart rate sensor that sends your numbers to another device, that simplicity can work in its favour.

Pros

+ Comfortable and lightweight

+ Strong 30-hour battery life

+ Bluetooth and ANT+ support

+ Simple physical on/off button

+ Works with a wide range of watches, apps and bike computers

Cons

− No onboard workout memory

− Only one Bluetooth connection

− No dedicated swim tracking

The post Best heart rate monitor 2026: chest straps & arm bands for exercise appeared first on Gadgets & Wearables.

I have now spent serious court time with the Slinger Bag, Pongbot Pace S Pro, Acemate tennis robot S10 and Lumistar Tero, and choosing between them is not really about finding the one with the longest specification sheet. Each takes a different approach to solo tennis, from cheap and simple repetition to structured drills and a robot that actually reacts to the ball coming back.

That is what makes this comparison more interesting than simply ranking them from best to worst. Depending on how you practise, the least sophisticated machine here could easily be the right choice, while spending twice as much could get you technology you barely use.

Tech specs compared

Specifications only tell part of the story here. Pongbot, Acemate and Tero all quote strong spin figures, for example, but they feel quite different on court because of how they deliver the ball, how drills work and whether the machine reacts to the player or the returned shot.

The biggest spec surprise is probably Tero. It is comfortably the lightest machine I have used here while still quoting the highest maximum ball speed, although its spin feels less aggressive in practice than the number suggests. Pongbot is the better choice if you specifically want heavier, faster and more demanding feeds, while Acemate’s selling point has little to do with winning the raw-spec contest.

Lumistar Tero

Tero is the machine I would probably point most recreational and intermediate players towards. It is exceptionally portable, takes about a minute to get running, and in my testing the feed has been consistent with no jams.

The wristband is a bigger deal than it sounds. Instead of walking back to the machine or constantly reaching for your phone, you can start and stop feeds or switch what you are working on with voice commands, and that keeps the session moving. There are 34 preset drills, custom sequences and 35 shot positions, so there is plenty to play with without the learning curve becoming excessive.

Tero does not watch the ball coming back at it. The wristband can provide position information, but there are no built-in cameras (unless you opt for the Pro version), so its training analysis is much less meaningful than what Acemate can produce. Spin is also the weakest part of its on-court performance, although pace is more than enough for the recreational and intermediate players I think this machine suits best.

Read my full Lumistar Tero review.

Acemate tennis robot S10

Acemate is best characterised as a tennis robot, and that is exactly why I like it. Rather than staying behind the baseline and waiting to fire the next programmed ball, the S10 uses two 4K cameras to follow your return, predicts where it is going and moves around the court on four omnidirectional wheels.

The timing is what makes the difference in practice. A slow return gives the machine more time before it sends the next ball, while a harder return brings the response sooner, so I found myself recovering and split-stepping much more naturally than I do against a fixed-interval machine. It still does not play exactly like another person, but of these four it comes comfortably closest.

There are compromises. The 60 mph top speed is below Pongbot and Tero, the rated battery life is shorter, and the S10 is more awkward to pull any real distance than either Slinger or Tero. Strong tournament players looking mainly for brutal pace and spin may therefore prefer Pongbot, but recreational and intermediate players who get bored hitting predictable feeds may find Acemate much more engaging.

The optional catching net is clever as well. It catches a good number of balls coming its way and cuts down on how much time you spend collecting them. Plus you get useful analysis of your shots with detailed statistics, along with AI suggestions on how to improve your game.

One thing stands out here. Of these four machines, I found Acemate to be the most fun to use. The cameras, court movement and reactive timing make sessions feel less repetitive and much closer to actually rallying with someone.

Read my full Acemate tennis root S10 review.

Pongbot Pace S Pro

Pongbot has its own advantages. It can fire balls at up to around 80 mph, generate strong topspin or backspin and hold more than 150 balls, while the battery is good for several long sessions rather than one afternoon on court.

What separates it from an ordinary high-powered launcher is the movement tracking. Sensors monitor your position at 100 Hz, allowing modes such as Recovery Trigger and Adaptive Rally to change the timing and pattern of feeds according to where you are and whether you have recovered into position. It is not watching the trajectory of your return in the same way Acemate does, but it is watching you, and that can make drills considerably more demanding.

The drill system is another strength. There are more than 500 presets, and custom drills let you change speed, spin, depth and placement ball by ball, so this is the machine I would take if my priority was structured repetition at a higher intensity. It is also the one of these four that gives stronger players the most room to turn the pace and spin up.

Read my full hands-on review of Pongbot Pace S Pro.

Slinger Bag

Slinger remains the easiest machine here to understand. You roll what looks like an oversized tennis bag onto court, set the speed and feed rate, adjust the elevation and start hitting. Add the oscillator and it can move the feed from side to side, which makes a major difference if you want to work on movement rather than stand in one spot.

Its biggest advantage is that it does two jobs at once. There is room for racquets, balls, drinks and other gear, so you do not necessarily need to bring a separate tennis bag, and the wheels make it easy enough to pull around despite the 15 kg weight. It is also the least intimidating option here if you just want hundreds of repeatable forehands and backhands without configuring an app first.

The limitations are equally obvious. Ball speed tops out at 45 mph, spin is not independently adjustable and drills depend heavily on where you position the machine and how you set the oscillator. After using the other three, Slinger feels basic, but basic is not automatically bad if that is all you actually need.

Our pick of the top connected rings

RingConn Gen 3 – the best value for money smart ring

Tech specs: 

• Infrared, Red and Green, temperature sensors
• Vibration alerts
• Vascular trend
• Up to 14 days battery life

RingConn has become one of the stronger options in the smart ring market, especially for those interested in sleep, recovery and long-term health trends. Its unobtrusive design still works well for 24/7 wear, while the updated app gives users plenty of data without pushing them into a subscription.

The third generation device is slightly thicker than before. But the trade-off is a larger battery, a new vibration motor, upgraded heart rate sensors, an improved temperature sensor and a newer 3-axis accelerometer. Battery life now stretches up to 14 days, while the universal wireless charging case is easier to live with than the older size-specific setup.

As noted in our hands-on review, Gen 3 stands out for strong sleep tracking, useful recovery-style insights and reliable daily activity monitoring. The new Vascular Trend feature gives it a more distinctive health angle, although it works best as a long-term trend tool rather than a replacement for a blood pressure cuff. Vibration alerts are another useful addition, even if the feature still needs more polish before it reaches its full potential.

RingConn Gen 2 Air remains the cheaper option. That model uses stainless steel rather than titanium, offers up to 10 days of battery life instead of up to 14 days, skips vibration alerts, does not include Vascular Trend and lacks sleep apnea pattern monitoring. It also comes with a wired charging dock rather than the Gen 3 universal wireless charging case.

Bottom line: RingConn Gen 3’s features, hardware and performance make it one of the most compelling alternatives to Oura Ring. It is comfortable, long-lasting and health-focused, with no monthly subscription fees. The exercise heart rate tracking still has limits at higher intensities, but for passive health tracking it is one of the best smart rings around.

Ultrahuman Ring Air – a great lifestyle improvement device

Tech specs: 

• Fighter jet grade Titanium reinforced with Tungsten Carbide Carbon coating outer shell.
• Infrared, Red and Green, temperature sensors.
• Around 6 days battery life
• 5 ATM water resistance

The Ultrahuman Ring Air distinguishes itself in the crowded smart ring arena with an insightful app that does more than just display metrics; it educates users about their health. Notable for its decently accurate heart rate variability, resting heart rate, and sleep tracking, the device also incorporates unique features like a circadian clock and stimulant restriction window.

As noted in our hands-on review, its comfortable, lightweight design and long-lasting battery make it easy to wear continuously. Frequent updates continue to add value. 

That said, the device isn’t without its imperfections. Both the step count and some Beta features could benefit from fine-tuning to achieve better accuracy. Additionally, the app’s interface could be simplified for an improved user experience. Nonetheless, the Ultrahuman Ring Air presents a compelling package, especially given its lack of subscription fees and a $350 retail price, making it a viable, cost-effective option for those looking to delve deeper into their health and wellness.

Worth noting, Ultrahuman Ring Air is currently unavailable in the US. Ring Pro should eventually replace it, but shipments have been delayed and we have not tested it yet.

Bottom line: The Ultrahuman Ring Air offers valuable health insights in a comfortable design. Despite minor flaws, its unique features and competitive pricing make it a solid choice for health tracking.

Ōura Ring 5: The best smart ring, but expensive

Tech specs: 

• PPG, negative temperature coefficient sensor, 3D accelerometer for movement
• Lightweight titanium with non-allergenic, non-metallic inner molding build 
• Free sizing kit
• Up to 9 days battery life
• 40% smaller in volume than before

The Oura smart ring puts lots of emphasis on sleep. With no buttons to push, it automatically detects and analyses your nightly rest and recovery by measuring heart rate, respiration rate, body temperature, movement, blood oxygen and other signals.

The 5th generation device brings a smaller and lighter design, with Oura claiming a 40 percent reduction in volume compared with Oura Ring 4. It measures 6.09mm wide and 2.28mm thick, with weight starting from 2 grams depending on size. The ring keeps the titanium build, 100-meter water resistance and IP68 rating, but the sensing system has been rebuilt with a new internal layout.

Battery life is now up to 6 to 9 days, depending on ring size and usage. Oura is also introducing an optional portable charging case, sold separately, which can provide up to a month of extra battery life. That makes Ring 5 a little easier to live with when travelling.

The software side is expanding too. Oura is adding features such as Health Radar, live activity tracking, GLP-1 medication tracking, clinical data uploads and improved Locate tools, with several additions also coming to older Oura rings. The subscription model remains, with the first month free for new members, then $5.99 per month or $69.99 per year in the US.

Bottom line: Oura Ring 5 is a thinner, lighter and more comfortable version of one of the best-known smart rings. The rebuilt sensors and smaller design make it a stronger option for sleep, recovery and long-term health tracking. But it remains pricier than much of the competition, especially once the subscription is factored in.

Luna Ring 2 – best simple subscription-free alternative

Tech specs:

• Titanium construction
• Optical heart-rate sensor, blood oxygen, skin temperature and accelerometer
• Around five to six days of battery life
• Portable charging case
• No monthly subscription

Luna Ring 2 is a straightforward smart ring that covers the main health and recovery features without overwhelming you with data. It tracks heart rate, heart rate variability, blood oxygen, skin temperature, stress and daily activity. The app turns these readings into sleep, readiness and activity scores.

In our hands-on review, sleep tracking proved to be one of its stronger areas. The ring reliably detected nights and shorter naps, while the app provided useful detail on sleep stages, consistency and breathing patterns. Its AI assistant also offers daily suggestions and lets you ask questions about your health data.

The ring feels light and comfortable enough for continuous wear, although it is slightly thicker than some alternatives. Battery life reached around five days in testing and could stretch closer to six with lighter use. The compact charging case makes regular top-ups easy and adds some flexibility when travelling.

Most daily health readings compared reasonably well with a Garmin watch and other smart rings. Exercise heart rate was the clear weakness, particularly as intensity increased. Overnight blood oxygen also produced a few questionable readings. Third-party integration remains limited and the app does not provide quite as much depth as RingConn, but its clean layout makes the information easy to understand.

Bottom line: Luna Ring 2 gets the fundamentals right. It offers good sleep tracking, dependable battery life and a refreshingly uncluttered app without requiring a subscription. It is a strong option for anyone who wants a capable health-tracking ring without Oura’s ongoing membership cost.

Wellue O2Ring: keep an eye on your SpO2

Tech specs: 

• Measure oxygen level (SpO2), pulse rate, movement
• Measurement interval – 1 second 
• Warning vibration for low oxygen, high/low pulse rate
• 15 grams weight
• 12-16 hours of continuous use on a single charge

This one is slightly different from other options on this list. The Wellue O2Ring predominantly does one main thing and it does it with medical grade accuracy – it tracks your blood oxygen. The company categories it as a general-wellness product. Other stats that you’ll get are heart rate and body movement.

The device has a built-in vibration motor that kicks into gear when it sees something out of whack. You’ll get an alert if your blood oxygen level or heart rate are outside of threshold you preset on the smartphone app.

There’s also the option of installing PC software in addition to the smartphone app. The software allows you to view and print a very detailed sleep report, which can also be exported as PDF or CSV files.

In our review, we found the device works really well. The ring is quite big in size so it is not something you would want to wear around the clock. But for measurements at home, in the office, or overnight it is quite useful.

It is worth noting the WellueO2 Ring is slightly more expensive than a typical fingertip pulse oximeter. But if you need overnight monitoring with alarms and long term tracking then it is probably the best option out there. For some, it might become their most important piece of jewelry.

Bottom line: The WellueO2 Ring is not your typical smart ring. Its main trick is that it monitors blood oxygen while you sleep. It will also alert you if it spots abnormalities.

Why get a smart ring?

Research suggests that we check our phone every six and a half minutes and much of this results from notifications that do not really interest us or can wait for us to attend to them later. With your cellular device tucked away in your pocket or bag, you can use a piece of jewelry to attend to only those notifications that deserve your attention. The rest can wait.

But potential use of smart rings goes further. Because your fingers have easy-to-sense arteries, some of these devices are also able to gather precise data on your body’s vital signals. They do this with sensors such as a 3d accelerometer, gyroscope, heart rate blood oxygen sensor and more. Much like fitness trackers.

Then there are smart rings that can be used to open a door lock or a smartphone or even send SOS messages. Such an accessory can be an easier option to use for some than a smartwatch. It is all a matter of preference. Some people are a fan of the concept, others are very much against it and prefer something sitting on their wrist.

How to choose the right smart ring

The right smart ring for you can be determined by a number of factors, including your specific needs, lifestyle, and personal style. Before making a decision, it is worthwhile to conduct some research and carefully consider your options. Here’s are some things to keep in mind:

• Determine your needs: The first step in selecting a smart ring is determining what you require it for. Do you want it to track your health and fitness, make contactless payments, control smart home devices, or provide security? The features you require will have a significant impact on your smart ring selection.
• Check compatibility: Make sure the smart ring you’re thinking about buying is compatible with your smartphone or other devices. Some smart rings are only compatible with certain operating systems or versions.
• Consider the design: A smart ring is a piece of jewellery as well as a functional device. When selecting a smart ring, keep your personal style and comfort in mind. Examine the available designs, materials, and colour schemes. Some brands also provide custom designs.
• Examine the battery life: The battery life of smart rings varies greatly. Determine how frequently you will need to charge the ring. Some rings can last for several days on a single charge, while others must be charged on a daily basis.
• Examine health and wellness features: If you want to track your health and wellness, see what sensors and features the smart ring has. Sleep tracking, heart rate monitoring, activity tracking, temperature monitoring, and so on.
• Examine security features: If you intend to use your smart ring to make payments or unlock devices, look into its security features. Biometric authentication, encryption, or a secure app could all be used.
• Consider the price: Smart rings range in price depending on their features and brand. Determine your budget and compare the features and quality of various rings within it. Also, keep in mind that some options come with an on-going monthly subscription fee.
• Examine the reviews and ratings: Examine user reviews and ratings to get a sense of the smart ring’s performance and dependability. Take note of comments about comfort, durability, tracking accuracy, and customer service.

Drawbacks or limitations of smart rings

Smart rings, though innovative and compact, come with their own specific set of limitations. The most obvious is that, because of their small size, they house limited battery capacity. Having said that, this has become less of a limitation with the latest generation devices which typically run for at least a week between charges. Battery deterioration is, however, a real thing and smart rings may lose some of their charging capacity after a year or two.

Another disadvantage is that, being worn on the finger, they’re more exposed to wear and tear from everyday activities. Rings from certain manufacturers are prone to scratching. So that’s something to be aware of.

If you are thinking about buying a smart scale, it doesn’t get any better than Withings scales. The company has made a name for itself in this product category, and other brands have some catching up to do. This site has published a number of reviews of its products, most recently the Body Scan. So make sure to check these out.

The range now has five clear steps

The range now spans a number of different scales, at different price points.

Body Smart remains the entry point. It covers more than 20 biomarkers, uses two bioimpedance frequencies up to 100 kHz and sticks to single-zone body composition. That means fat and muscle mass, hydration level, visceral fat, BMI, basal metabolic rate and standing heart rate. For most people who want a smarter version of a normal scale, this is the basic Withings pitch.

Body Comp moves things along without adding a handle. It raises the count to more than 30 biomarkers and adds vascular age plus a Nerve Health Score. Withings describes this as detecting early signs of diabetes-related complications, so this model sits closer to a health check-up than a fitness scale. It still uses two frequencies up to 100 kHz and single-zone body composition, so the upgrade is more about health signals than body mapping.

BodyFit is the interesting middle option

BodyFit is the new model that could cause the most confusion. It costs $279.95 in the US and jumps to more than 40 biomarkers, but the real shift is the retractable handle. That enables 6-zone analysis across the body rather than one averaged reading from the feet.

It also uses 13 bioimpedance frequencies up to 800 kHz, which puts it ahead of the original Body Scan on that specific line in the table. But BodyFit does not have ECG, atrial fibrillation detection or Nerve Response Score, so it is not a full health station. It might fit in the sweet spot for someone mainly interested in body composition, fat and muscle distribution, visceral fat and vascular age.

Body Scan still has a role

The original Body Scan remains the first proper health station in the lineup. It includes more than 40 biomarkers, 6-zone body composition, a retractable handle, standing heart rate, vascular age, 6-lead ECG and atrial fibrillation detection. It also adds Nerve Response Score, with stress response and recovery insights.

That makes Body Scan a different product from BodyFit, even though BodyFit looks strong on body composition. Body Scan leans harder into cardiovascular and nerve health. The comparison sheet also shows Glucose Resilience as a new metabolic feature for Body Scan, though this is one of those areas where buyers should watch the app rollout and Withings+ requirements closely.

BodyScan 2 is the top model, but not a simple upgrade for everyone

BodyScan 2 pushes the range to more than 60 biomarkers. It uses 13 bioimpedance frequencies up to 800 kHz, keeps 6-zone analysis and adds improved segmental measurements. The handle also gets touch-sensor electrodes, a built-in display and improved readability, which should make daily use less awkward than reading everything from the scale platform.

The extra health features are the bigger story. BodyScan 2 adds blood pressure insights, Heart Age and blood oxygen levels. It also keeps vascular age, 6-lead ECG, atrial fibrillation detection and Nerve Response Score. On paper, all of this sounds great – if you’re into that level of detail.

The subscription piece needs watching

What needs watching is the Withings+ subscription. It now sits across the range, but not every model gets the same experience. The comparison sheet shows Body Smart, Body Comp and BodyFit with Personalized Health Priorities, Weekly Plan and BodyPath. Body Scan and BodyScan 2 go further with cardiologist review included and Longevity Intelligence.

This is where the buying decision becomes less clean. Heart Age and Glucose Resilience sound like headline features for BodyScan 2, but Withings says those sit behind Withings+. So the question is not only which scale has the sensor hardware. It is also which insights remain useful without paying for the extra software layer.

Which one makes the most sense

Body Smart remains the sensible entry model if weight, body composition and basic health trends are enough. Body Comp adds useful health markers without the larger handle-based design, so it fits buyers who want vascular age and nerve health but do not care about segmental body mapping.

BodyFit looks like the best fit for people who mainly want better body composition data. It brings the handle, 6-zone analysis and 13-frequency bioimpedance at a much lower price than BodyScan 2. Body Scan remains the better choice if ECG and nerve response are important, especially if it gets discounted now that BodyScan 2 has arrived.

BodyScan 2 is the one for buyers who want the newest Withings health platform and are comfortable with the subscription angle. It has the broadest mix of body composition, cardiovascular, metabolic and longevity-style metrics. But the arrival of the new model also makes the cheaper options look more interesting, because the range now has clearer tiers than the product names suggest.

Garmin has announced today the high-end HRM 600. The company’ ‘s current range now consists of several different heart rate monitors. In this article we explain the differences between them.

The company may be known for sports watches, but it also dishes out GPS technology across a diverse range of markets, including aviation, marine, tracking and mobile apps. If you own one of its sports watches, you are probably aware that Garmin also makes heart rate chest straps.

Still better than wrist heart rate monitors

The value of such devices are that they are much more precise than something attached to your wrist. Garmin has a decent smartwatch heart rate sensor, but this still trails heart rate chest straps when it comes to accuracy. This is particularly evident with high intensity exercise such as HIIT – your data will sometimes lag. That is why many cyclists and runners like to attach a heart rate strap before heading out to exercise.

Essential reading: Top fitness trackers and health gadgets

Interestingly, Garmin has not yet dished out anything that works from the mid or upper arm. We say interesting, because other companies have gone down this route. Polar is one such example with its OH1+ strap, but there are other examples. In our mind, it is just a matter of time before Garmin gets into this space.

Technical specs compared

For now, you have a choice of five Garmin heart rate chest straps. This includes HRM-Swim, HRM-Dual, HRM-Pro, HRM-Pro Plus and HRM-Fit.

There is also Garmin HRM-Run which can be picked up on some retail sites, along with HRM-Tri and HRM Dual. The first has been around since 2013, the second since 2015. So it’s safe to say they are packing older heart rate tech smarts. It is not a surprise, therefore, that both of these have been officially discontinued as they have been superseded by newer heart rate monitors. This is also the case with the last on this list, which saw the light of day in 2019.

You might be able to pick up some great discounts on these devices but know that you are running a risk as the product as not sold in Garmin’s store any more. Always best to buy the latest technology.

So it comes down to the other heart rate monitors. Here’s a table showing how their technical specs stack up.

HRM Dual vs Swim vs Pro vs Pro Plus: functionality compared

The HRM-Dual has been replaced by the HRM-200 as of the start of 2025. This updated model offers better accuracy, improved usability, and enhanced data security, making it a great budget-friendly option for reliable heart rate tracking. It supports encrypted data transmission for privacy and allows multiple device connections at once—up to three Bluetooth and unlimited ANT+—but doesn’t include advanced features like running dynamics or built-in storage.

The HRM-Pro and Pro-Plus are basically the same, with the only difference being how the battery is accessed. The Pro-Plus lets you twist the module to change the battery without needing any tools, which is a pretty nice touch. These models have extra features like Running Dynamics, run power support on compatible Garmin watches, and the ability to store data offline. They’re better suited for athletes who need more in-depth tracking and want to get into the nitty-gritty of their performance.

Then there’s the HRM-Swim, which is perfect for anyone who spends a lot of time in the water. The strap is designed to stay put while you swim, and it can store and forward your heart rate data to compatible devices. If you’re a swimmer, this one’s definitely a step up compared to the others.

What about the HRM-600?

So how does the newest addition compare? Well, it is the highest spec of the bunch.

As some of the others, it features a detachable sensor for easy cleaning and comes in two strap sizes: XS-S and M-XL. The 5 ATM water resistance means it’s swim-ready.

But a rechargeable battery replaces the usual coin-cell. Charging is done via Garmin’s familiar 4-pin connector, and with moderate use, it can last up to two months on a single charge.

The HRM 600 can also operate independently. It can log heart rate, steps, speed, and distance even without a connected watch, turning it into a versatile training companion. ANT+ and Bluetooth support is there, of course.

For runners, this strap goes beyond basic heart rate. It captures cadence, stride length, and vertical oscillation, offering a deeper view into running mechanics. Garmin has also added a new metric called step speed loss, which measures how much a runner slows down on foot strike. It’s a useful indicator of running efficiency that could help spot form issues or fatigue early.

A heart rate monitor for women

There is also something specifically designed for women. The HRM-Fit, priced at $150, is uniquely designed to attach securely to medium to high support sports bras using three anchor points, accommodating various body types. This design ensures stability and comfort during intense workouts.

Functionally, the HRM-Fit is at the high-end. It supports advanced workout tracking, including metrics like vertical oscillations, ground contact time, and stride length, offering in-depth analysis of running form. The device is built for durability, with a battery life of up to one year based on daily one-hour usage, and features a tool-free door for easy battery replacement.

In comparison to other Garmin heart rate monitors, the HRM-Fit introduces a specialized approach. While models like the HRM-Tri and HRM-Run are tailored for triathletes and runners with specific metrics, the HRM-Fit is designed for women seeking a comfortable, reliable heart rate monitor that integrates effortlessly into their fitness routine.

The bottom line

Garmin has a nice selection of Garmin heart rate chest straps. Nothing that works from the upper or mid-arm just yet, but if you are serious about your running or cycling pursuits you will want one of these.

Top of the range is now the HRM-600. It is closely followed by Pro-Plus and HRM-Fit for women. So you are going to want one of these.

If, however, you want to save some cash, then HRM-200 and HRM-Swim are your options. There really isn’t any other reason to choose one of these two. The second costs a bit more than the first but has better water-proofing, onboard storage and swim tracking ability.

Whichever device you choose, take comfort in knowing it will spit out accurate heart rate stats and work seamlessly with your Garmin watch. The other option is to go for another manufacturer’s strap. These will also play nice with your Garmin timepiece. Our device of choice is the Polar OH1+ but there are other good ones.

Check out the Garmin range of chest straps on the company’s website. Some of them can also be picked up on Amazon HRM-Swim, HRM-Pro range).

Garmin has plenty of options of its own, but you can see how they stack up against Polar, Wahoo and others in my guide to the best heart rate monitors.

Which Garmin Watches support the ECG app?

Best answer: The first Garmin watch with support for the ECG app was the Venu 2 Plus. It received approval for the feature back in January 2023. That is when the Food & Drug Administration (FDA) gave it the go-ahead. This opened the door for the company to sell devices with this feature in the United States. Since then a number of other Garmin watches have received this ability.

Here is the full list as it stands at the moment – along with the minimum software version you need to be running on your watch.

• D2 Mach 1 Pro (software version 14.68 or newer)
• еріх Pro (Gen 2) – Standard Edition | epix Pro (Gen 2) – Sapphire
• Edition (software version 14.68 or newer)
• Fenix 7 Pro – Solar Edition | fenix® 7 Pro – Sapphire Solar Edition (software version 14.68 or newer)
• fenix 7S Pro – Solar Edition | fenix® 7S Pro – Sapphire Solar Edition (software version 14.68 or newer)
• fenix 7X Pro – Solar Edition | fenix® 7X Pro – Sapphire Solar Edition (software version 14.68 or newer)
• quatix 7 Pro (software version 14.68 or newer)
• tactix 7 – AMOLED Edition (software version 14.68 or newer)
• Venu 2 Plus (software version 11.21 or newer)
• Venu 3 | Venu® 3S (software version 7.07 or newer)

The feature is country dependent

Having one of these watches doesn’t guarantee access to the ECG app, as its availability is contingent on the country you’re in. The ECG feature requires Garmin to obtain clearance from each country or region’s regulatory authority before it can be offered. For example, European users currently face limitations in accessing this feature. As it stands, only users in the United States, Taiwan, Hong Kong, and Vietnam can utilize ECG on their Garmin watches.

Essential reading: Top fitness trackers and health gadgets

As can be seen, this is a short list of countries. That’s the bad news. The good news is that there is a way around this. But it is not recommended by the manufacturer and doing so requires several steps that could be risky. Additionally, there is always a risk that using unauthorized methods to enable features on your device could damage it or void your warranty.

The steps involve changing your account location to the US, using a VPN and GPS location spoofer app, and turning off WiFi. Some users report needing to restart the watch after this process. You can read our full article on how to activate the ECG app in currently un-supported countries.

How to take an ECG on a Garmin watch – a quick recap

Garmin’s ECG app isn’t a medical replacement but offers insights into your heart rhythm. It takes a 30-second pulse scan to look for signs of atrial fibrillation. There are limitations: you must be over 22, still (no exercise or water), and away from strong electromagnetic fields.

Using the app is simple. Ensure your watch fits comfortably, open the app, and follow the instructions. Rest your arm on a table and touch the bezel with your thumb and forefinger. After 30 seconds, you’ll see your results. The app displays your heart rhythm status, including normal sinus rhythm, inconclusive results, high/low heart rate, or potential atrial fibrillation (which warrants a doctor’s visit). That’s all there is to it – check out our full guide.

What is HRV?

Recovery is done by a combination of sleep and time not spent training. It is at this time that heart rate and blood pressure are normalized, your body’s energy is restored and your muscles strengthen and grow. Sleep is a particularly important part of the equation, as it serves to maintain your physical health and support healthy brain function.

One of the best ways to track recovery is by monitoring your heart rate variability (HRV). Not many people know that a heart does not beat with a steady rhythm. The intervals vary from one heartbeat to the next. HRV measures this variation in the time interval between heartbeats.

It’s a bit counter-intuitive, but unlike your resting heart rate, you should be aiming for a high HRV. This is because a healthy HRV should not beat at a perfect tempo. A low HRV indicates less resilience. This happens when you are training hard, under stress, not sleeping enough or are ill. The trick is knowing your baseline HRV and then following how these values change from day to day.

Essential reading: Top fitness trackers and health gadgets

Better recovery starts by knowing what’s happening inside your body. While this industry is still in its infancy, there are already a few wearables that offer advanced recovery metrics. In this article, we provide our pick of such devices.

Devices that track your HRV

Whoop 4.0

As. noted in our hands-on review, Whoop is not just a fitness tracker; it’s a tool that emphasizes the importance of self-care, highlighting the need for adequate sleep and recovery. Core to the system is a wristband that measures your vitals stats non-stop more than 100 times per second. The physiological markers are used to asses an athletes readiness to perform each day. The thing also offers detailed guidance on how much sleep and rest is needed to recover, heart rate variability, respiratory rate and more.

In addition to a daily recovery score, there’s also something called a Strain Coach. This is a real-time measure of cardiovascular exertion that is tracked on a 0-21 scale. It works both for individual workouts and your entire day. You’ll also get a daily goal based on your recovery metrics.

Whoop is a a holistic platform that encourages you to experiment with lifestyle changes. By using its journal feature, you can explore the effects of various factors like diet (vegetarian or otherwise), alcohol, caffeine, and supplements on your well-being. These small but significant adjustments can dramatically improve your quality of life.

It’s a misconception to view WHOOP as a device solely for elite athletes. While it might not cater to the occasional exerciser, it’s incredibly beneficial for those who are serious about their training regimen. If you’re someone who consistently pushes their limits, WHOOP offers a new perspective. It doesn’t hold you back from challenging yourself; instead, it equips you to do so more effectively.

WHOOP operates on a subscription model where the hardware is provided at no cost, but users choose from various subscription plans. The monthly cost varies, typically falling around $20, $25, or $30, depending on the membership tier you select.

RingConn

RingConn is emerging as a strong contender in the smart ring segment. Its sleek design ensures it blends seamlessly into everyday life, while its straightforward setup appeals to a broad user base.

The RingConn app is rich in data, which may initially seem daunting to some users. However, its depth of insights is impressive, enhanced by compatibility with platforms like Apple Health and Google Fit.

As noted in our hands-on review, for those interested in recovery data, RingConn excels. Its accuracy in tracking resting heart rate, heart rate variability, and sleep patterns is commendable, showing strong parallels with established names like Whoop. Although there’s room for improvement in exercise heart rate tracking, the company’s commitment to continuous updates and community engagement is promising for future enhancements.

In comparison to its main rival, the Oura Ring, RingConn stands out. It offers a compelling mix of features and performance at a more accessible price point, without the burden of a monthly subscription.

As RingConn evolves with ongoing updates, it’s exciting to think about its future potential. For those seeking a discreet wearable alternative that focuses on recovery metrics, RingConn is a noteworthy option.

Ōura Ring

The Ōura ring is wrought out of titanium and is water-resistant to 150 meters. The ring has a seamless, non-allergenic inner molding and comes in Silver, Black and Stealth options.

Although it does track physical activity during the day, most of the interesting stuff happens during sleep. The 3D accelerometer and optical heart rate sensor capture information on individual sleep stages (Deep, REM, Light), and periods of wakefulness.

For overnight recovery you’ll get info on heart rate, pulse amplitude, HRV and respiration rate. There’s also something called a ‘Readiness Score’. This is displayed as a percentage, and tells you whether you need to adjust the intensity and duration of your day’s activities.

Polar watches

Polar has recently introduced HRV readings in its Ignite, Vantage and Pacer series. These are GPS fitness watches that are marketed as versatile training toola for a variety of sports and activities. What’s most unique about them that they have advanced sleep analysis, overnight recovery insights and personalized and adaptive training guidance. These take sleep parameters, heart rate measurements and recovery into account to offer deep insights into the state of your body.

As part of this you get something Polar calls Nightly Recharge which fluctuates between -10 and +10. This quantifies how quickly your autonomic nervous system calmed down during the first four hours of your sleep. The info is tied in with your daily activity stats to let you know whether to take a days rest or train as usual. In our review of Ignite we found all of this works pretty well and adds a new dimension to your training and recovery.

VIITA Watch

There are several VIITA Watches in the collection, some of which offer a very premium design. The functionality, though, is where it gets more interesting. Apart from the basics which come on any half-decent sports watch including GPS, Race HRV has stress and regeneration monitoring 24/7 based on heart rate variability.

The latest iteration is called VIITA Race HRV. In addition to recovery metrics it automatically calculates water demand based on vital signs. This is done by combining data of the micro-movement sensor, pulse, heart rate variability, Regeneration status, Stress progression, movement patterns and sleep time and quality.

Amazon*

Fitbit devices

Yes, your Fitbit can track HRV, too. As long as you own a Charge 3 or above, Inspire 3 or one of its smartwatches. That’s the good news. The bad news is that you’ll need a Premium monthly subscription to access the readings. It’s all part of the health dashboard.

The subscription runs at $9.99 per month or $79.99 per year. You’ll get access to raw HRV data which is excellent. The info is coming from your wrist so it will not be chest band quality, but it should give a good overview of your stress. The Premium monthly subscription gives you access to some other data such as skin temperature variation.

Garmin watches

With the Forerunner 255 and 955, Garmin has introduced something called HRV Status. Previously, Garmin watches had the ability to take HRV measurements, but only on-demand. The difference now is that these types of measurements are taken while you sleep. In the morning you get your average value for the night, and this is compared to your seven day HRV average and your long-term average. The latter takes about three weeks to establish.

These watches also have something called the Training Readiness Score. This takes into account your HRV, training status and load, sleep, stress and more to spit out a value between zero and 100. It quantifies your level of preparedness to face a hard day of training.

The Forerunners are no longer the only Garmin watches with the ability to capture HRV. Any of the recent Fenix devices, Epix, Venu and other high-end devices also have this ability.

If you are after a sports watch, you won’t go wrong with a Garmin. Their have an excellent range of devices that spit out a wealth of health and fitness stats, as well as a boat-load of performance metrics.

Yes, the Apple Watch also has the ability to track HRV. This is done automatically, but you can also trigger a reading manually. The feature was introduced with watchOS 4.

A measurement is captured when you first wake up in the morning. Your Apple Watch will monitor your HRV for one minute and then work out an average. It uses its own proprietary algorithm for the calculations.

To view the results, head over to the Health app on your smartphone and the HRV page. You can find it in the Heart subsection. The analysis pretty much ends with charting your readings (by day, week, month or year) and Apple doesn’t currently offer more detailed insights into the results.

A manual HRV reading can also be forced at any time by starting a Breathe session on the device. Once you’ve completed the Breathe session you can view your HRV on your iPhone.

The post Best wearables to track recovery with heart rate variability appeared first on Gadgets & Wearables.

Smart scales connect wirelessly to your smartphone, tablet or computer to fitness apps. Step on one of these, and your weight data will magically find its way to a corresponding software on your mobile device or a Web dashboard. Using the app or dashboard, you can then track your progress over time which should help you make healthy choices as far as diet and exercise.

Scales that also measure body fat and other advanced metrics do this by sending a low electrical current through one foot and reading the current with a sensor under the other foot. The current passes through fat more slowly so the scale calculates the amount of resistance to come up with a body fat percentage. This is often referred to as bioelectrical impedance analysis (BIA).

Essential reading: Top fitness trackers and health gadgets

Consumer Reports tested six popular bathroom scales a while ago and came to the conclusion that while they were all excellent at measuring body weight, none were particularly accurate when it came to measuring body fat. But they were consistent which means the scales can be used to track relative gains and losses over time as they are comparing like with like.

This doesn’t really come as much of a surprise. The accuracy of body fat and other more exotic measurements such as visceral fat, body water, protein, lean body mass leaves a bit to be desired. These are estimates rather than something that is measured precisely. Hence, many of us have learned to ignore them. The readings are more a nice-to-have rather than something that should be religiously followed. At least until accuracy of such measurements on these types of devices improves. Which will come.

Generally, we can separate smart scales into two camps. The ones that come from well known brands such as Fitbit, Withings and Garmin, and the dozens and dozens of scales released by the lesser known companies. These are generally cheaper, but in many cases also less precise. This article focuses on the more established brands. In our mind, paying a bit more extra is worth it as you get a better quality product, advanced software and more accurate readings

The best smart scales of 2023 – here’s our pick

Withings Body Smart

Let’s cut to the chase right away. Scales produced by Withings are our pick of the bunch. They look great and do the job extremely well. There are several options you can choose from.

One of these is the Body Smart scale. As noted in our hands-on review, the gadget stands out for its cost-effectiveness, feature set, and reliability. Once set up, Body Smart requires minimal attention, save for routine weigh-ins. It offers an array of health-related metrics, impressing especially with its weight measurements, accurate to two decimal places.

The aesthetic of the scale is contemporary and clean, enhancing the user experience. Its interface is intuitive, and the multiple modes it offers are tailored to meet diverse requirements. The scale’s multi-user capability also makes it an excellent option for household use.

Though it may lack some of the advanced features found in pricier models, the Body Smart scale excels in essential areas. It serves as a dependable, precise, and user-friendly instrument for those keen on monitoring their health metrics.

If you love gadgets and find tracking your weight useful to help you diet or maintain a healthy weight, you won’t go wrong with the Body Smart. This is a quality product that comes at a reasonable price.

Withings Body Scan

Another smart scale that we reviewed recently, the Withings Body Scan scale transcends the role of a mere weighing apparatus. It positions itself as an all-encompassing health hub that delivers an extensive range of metrics for wellness monitoring. Priced at $399.95, this is not a casual purchase, but it offers value for those committed to in-depth health tracking.

Aesthetically, the scale marries form with function, boasting a robust tempered glass surface and a handlebar that elevates both its design and measurement capabilities. Seamless connectivity is ensured through Wi-Fi and Bluetooth, allowing for effortless data synchronization. Battery longevity is another strong point, with a single charge lasting up to a year and recharging facilitated through a standard USB-C cable.

When it comes to precision and dependability, the Withings Body Scan scale is designed to excel. It goes beyond mere weight measurement to provide a comprehensive set of metrics such as segmental body composition, metabolic evaluations, and cardiac health indicators. The built-in ECG monitor is especially significant, acting as a preliminary alert system for potential heart rhythm anomalies.

For those in search of a smart scale that offers more than basic weight metrics, the Withings Body Scan scale stands alone in its capabilities. Its broad range of features, reliable performance, and sophisticated design make it a worthy investment for individuals serious about health and well-being.

Fitbit Aria 2

Long overdue for an update, the original Aria scale was released back in April 2012. At the time, it was one of only a handful of connected scales on the market.

Aria 2 was introduced a couple of years ago. It has a fresh design and a few other updates, but its core features remain largely the same. This means the scale tracks weight, BMI, body fat percentage, with now the addition of lean mass. Just like its predecessor, it can recognise up to 8 users and you can set weight goals with a daily calorie plan, log food and other workouts.

Fitbit says its much easier than before to set up the new scale and you can do it over the smartphone using the app. It also offers more accurate readings.

If you’re looking to lose weight or just keep tabs on your current weight, this scale makes a good choice. Particularly if you own a Fitbit fitness tracker or smartwatch as it makes sense to buy from the same brand. It is simple to use. Your weight is transferred to your Fitbit dashboard so that it sits there along with all your other stats.

Amazon*

Garmin Index S2

Garmin is also on the second generation of its scale. The Index S2 is the successor to Garmin’s original S1 scale. Overall, the S2 comes with some nice new upgrades.

The S2 has a sleeker design then its predecessor and bright LCD colour display whilst retaining the same 9 month battery life. You also get enhanced accuracy of sensors and some useful features which allow you to follow your trends without reaching for the smartphone app.

Both generations dish out info on weight (lbs, kg, st), body mass index (BMI), body fat, water percentage, bone mass and skeletal muscle mass. If you don’t want to be bothered with the other metrics, the S2 allows you to choose a weight only option. It also allows for customisation of widgets.

If you are the owner of other Garmin devices you might want to opt for this one due to easy integration with the Garmin Connect app. You can also check out our separate piece with a detailed comparison between the S2 and S1 scale.

It’s worth noting – these scales are the only body composition monitors that are integrated directly into the Garmin ecosystem of products. You can connect other products such as the Withings scale by using workarounds such as third party apps. One of the often used ones is Myfitnesspal.

Amazon | Garmin*

Xiaomi Smart Scale

Perhaps not as feature rich as some of the other connected scales, the Xiaomi scale sells at about half the price of the leading brands.

The device tracks weight and BMI, and connects via Bluetooth to Xiaomi’s Mi Fit iOS and Android apps, so you can track your weight over time. It is capable of managing the weight of up to 16 people with its app, so its suitable for the whole family.

There are 161 LEDs which light up to show your weight. The overall body of the scale has a smooth design and round edges, and is protected by tempered glass panels. The display itself is embedded into the body.

This is a great product, particularly when you factor in the low price. If you own other Xiaomi products such as a smartwatch or fitness band, it makes sense to purchase from the same brand.

Amazon*

Polar Balance Smart Connected Scale

The Polar Balance scale features a large display, to ensure that the digits are easily readable, and a splash-proof glass design. The scale provides you with your weight and BMI, and can be used by up to 10 different people. The biggest selling point of this device though, is the software.

Once you have customised the settings in your profile, the app and web service will provide you with motivational guidance on how to reach your daily activity goal. The app works on the basis that 60% of the excess calories should be cut from your diet and 40% should be burned with activity.

Daily activities such as steps, distance and calories are recorded from one of Polar’s fitness trackers (if you own one), and the food intake you will need to record manually. A interesting aspect is the beautifully designed Weight Loss Speedometer. It comes in the form of an infographic that visually shows how close you are to reaching your weight goals.

Amazon*

Yunmai Wireless Bluetooth Scale

This popular budget option comes from a Chinese manufacturer. Rather impressively, Yunmai measures 10 different body composition stats, including weight, BMI, BMR, hydration, bone mass, body age and more.

It also comes with a well designed app that offers you guidance to help you reach your goals. You can chart your weight fluctuations on a daily, weekly, monthly and yearly basis. You also get a composite ‘Health score’ each time you weigh yourself, along with a ‘Fitness Age’ score.

We have to commend Yunmai. Rather than just providing you with raw data and letting you make sense of it, the company tries to show you what exactly you need to do to improve your health. After all, a thin person is not in every case healthier than an overweight person.

All in all, in terms of value for money, this is a great choice.

Amazon*

QardioBase 2

The second generation QardioBase retains the signature circular “floating” look of its predecessor but enhances it with a wider base for added stability. This was one of the main gripes with the previous generation. A new rechargeable battery has also been added that runs for up to a year between charges. The screen is brighter and crisper and there is a better haptic engine installed.

Qardio says it has enhanced the sensor system and introduced new and improved algorithms. This means your weight, body mass index and body composition (% muscle, fat, water, bone) measurements will be more accurate than before. There is also a unique Pregnancy Mode which helps expecting moms safely track their progress during this happy time and beyond.

All measurements are automatically be saved in Qardio’s secure cloud. And you can optionally sync with Apple Health too.

Amazon | Qardio*

Fitbit Aria Air

Fitbit’s most recent scale is designed to be light on your wallet. It only retails for $49.95 on the company’s website. That is less than half of what you’d pay for its more expensive siblings!

You sacrifice some of the functionality, for the lower price. There’s only Bluetooth sync (so no wi-fi connectivity) and the scale only captures info on weight and body mass index (BMI). And that’s pretty much where it ends. It’s a no-nonsense device which spits out the essentials. The more expensive Aria scales also track body fat percentage and lean mass, hence the higher price.

Design-wise, the scale does not stray too much from other offerings in the Aria range. It features a simple square-ish design that comes in a choice between White or Black. The LCD display is still there although it now lacks the metal ring around it.

Aira Air is great if you are looking for a budget smart scale that is user friendly and that integrates into the Fitbit app and platform of products. You step on it, step off – done. The scale plays nice with Fitbit’s Premium Subscription service, you can set goals, follow weight trends, connect to third party apps and access the Community section for support from other Fitbit users and bragging rights.

Amazon*

Withings Body Cardio

Body Cardio is another scale from French-based Withings. The device looks great, plus you get a host of data some of which is to do with your heart health. One of these metrics is called Pulse Wave Velocity (PWV).

This is info that cannot be found on any other smart scale. It measures arterial stiffness by calculating the time it takes for the pressure wave generated by the heart to travel along the arterial tree and reach your feet. The resulting value can be useful in assessing your risk of having or developing hypertension. Faster speeds indicate stiffer arteries.

The company has also introduced a new Vascular Age metric. It builds on PWV to provide users an even easier way of understanding their heart health. It does this by taking the readings and comparing them to people your age and physical characteristics.

Beyond that you get everything you can wish from a scale and more. What sets this scale apart from the competition is the variety of health data it records. As well as standard weight, BMI and fat percentage figures, every time you step on the scale you get a host of other data including a mini heart health assessment. This is plenty for most people.

In our testing we were very impressed with the Body Cardio. From setup that went without a hitch, to ease of use, to use of data – it simply does the job. An example of how all smart home health appliances should be.

What does an ECG sensor do?

With each beat your heart sends out an electrical impulse. Although this electricity amount is very small, it can be picked up with ECG (EKG) electrodes attached to the skin. You’ve probably seen ECG monitors in movies. It is the medical apparatus which generates squiggly lines which let you know whether your heart rhythm is showing signs of atrial fibrillation or is beating in a normal pattern.

Essential reading: Top fitness trackers and health gadgets

While there is no shortage of heart rate training chest straps, ECG monitors have not been available to amateur fitness enthusiasts until recently. Now there is a healthy range of devices which are capable of dishing up a pulse waveform similar to what you’d get from a professional electrocardiogram. They come both in the form of smartwatches and other types of devices.

It is worth noting, most of these wearables will not do a perfect job. But the hope is they may warn some people who do not know they are living with a heart condition.

Of course, self-diagnosis should always be avoided, and you should refer to your physician for a medical interpretation of your readings. With that in mind, here’s a selection of devices capable of taking ECG measurements.

Wearables that come with an ECG sensor

QardioCore

QardioCore is a smart, wearable ECG monitor. A number of years in the making, the device is designed to improve detection and management of cardiac conditions.

Six subsystem layers of QardioCore’s sensor system record and analyze over 20 million data points daily along with other important heart metrics. To use, simply wear it around your chest as you would a heart rate band.

According to Qardio’s website, the device has been clinically validated and approved by the FDA to accurately and continuously track your complete heart health. The gizmo records your electrocardiogram, heart rate, heart rate variability, body temperature, respiratory rate, activity and stress level. An impressive list, indeed.

QardioCore is portable, discreet and water resistant and works with the companion Qardio app where you can share your measurements with your doctor, trainer or family members. Alongside the ECG trace, the accompanying smartphone app offers friendly data visualization that is simple to understand.

QardioCore is a nice bit of kit but fairly expensive. It is particularly suited for people with increased health risk caused by family predisposition, history of heart attacks or strokes, high blood pressure, high cholesterol, diabetes and excess weight.

Amazon | Qardio*

AliveCor KardiaMobile 6L

Many expected AliveCor to be squashed by the launch of the first ECG enabled Apple Watch. However, the company is still going strong as it continues to sell its ECG accessories. 

Its most most recent product is the KardiaMobile 6L. Unlike its earlier product range which has a single lead ECG, this one comes with a 6-lead system. It can detect AFib, Bradycardia, Tachycardia and normal heart rhythm with more accuracy and detail than its competition. In a care clinic ECG readers have 12 leads which are placed across a patient’s chest to pick up heart data. More leads mean a better view of your heart.

To take a measurement rest your thumbs against the two electrodes with KardiaMobile 6L facing you. Then, touch the bottom electrode to the bare skin of your left knee or left ankle. It takes about 30 seconds to complete a reading.

Amazon / Alivecor*

AliveCor KardiaMobile Card

KardiaMobile Card is another recent addition to AliveCor’s product range. Looking exactly like a credit card, this is the slimmest electrocardiogram (ECG or EKG) device in existence. The single-lead ECG gizmo is built to resist weather, water, and wear and tear. There’s no charging and the card should work for a couple of years with the internal battery intact.

It takes just 30 seconds to complete a reading at which point the data will be synced via Bluetooth to the smartphone app. KardiaMobile Card has the ability to detect six of the most common heart arrhythmias. This is something no other personal ECG on the market can beat.

We tested out the card a few months ago and enjoyed the ease of taking readings and the simple to use smartphone app. With the ability to share your results and even send them to professional clinicians for review – the device presents itself as a complete ECG monitoring solution.

Alivecor*

Apple Watch Series 4 & above

Much has already been said about the Apple Watch. With each passing year, the device is edging closer to becoming your must-have health guardian. In addition to other hardware and design improvements, Series 4 and above come with fall detection, irregular heart rate alerts, low/high heart rate alerts and more. Then there is, of course, the FDA-approved single-lead ECG sensor.

Readings are on-demand. To take a measurement simply rest your finger against the digital crown while wearing the watch. This creates a closed circuit between the digital crown and the sensor on the back. Built in electrodes will then work to detect electrical impulses from the heart.

It takes just 30 seconds for a pulse waveform to be generated. You’ll get a full report and the app will let you know if your heart rhythm is normal or there are issues. There is also a PDF with all the info so you can forward the info on to your doctor.

The Cupertino outfit states that the ECG monitor will not do a perfect job. But that it is perfectly adequate for most people as it can flag up certain heart conditions.

Initially, the fear was that the system would throw up many false positives and overwhelm doctors with worried Apple Watch owners. Thankfully, this did not happen. 

“The ECG app is intended for over-the-counter (OTC) use. The ECG data displayed by the ECG app is intended for informational use only.” Apple writes.

“The user is not intended to interpret or take clinical action based on the device output without consultation of a qualified healthcare professional. The ECG waveform is meant to supplement rhythm classification for the purposes of discriminating AFib from normal sinus rhythm and not intended to replace traditional methods of diagnosis or treatment.”

Amazon*

WIWE

WIWE is a clinical-grade ECG monitor. The size of a business card but slightly thicker, it can fit easily into your pocket or bag. You might even manage to slip it into your wallet!

The gizmo goes further than most other such devices on the market in that it offers more detailed analysis of your readings including irregularities in the ventricular department. And it has been proven to do this with 98.7% accuracy. Plus there are also some extras such as SpO2 measurements and the ability to count steps.

But the main benefit of using the device is its accuracy. While smartwatches may offer more convenience, the ergonomic configuration of WIWE is more conducive to obtaining precise ECG readings. Keeping your thumbs or index fingers on electrodes of a device that can be placed on a flat surface or held in both your hands will dish out more reliable results than resting your finger against something sitting on your wrist.

In our review we found WIWE worked exactly as advertised. If you have reason to be concerned about your heart health or already have a diagnosed condition, this little device may end up being a life-saving investment.

You can read our detailed review on this link.

Withings BPM Core

Honored with a CES Innovation Award, Withings Core functions as a BPM, ECG and digital stethoscope. The device is simple to use, convenient and provides a wealth of useful information. But the main novelty is that this is a 3 in 1 product.

Withings Core allows for medically accurate monitoring of hypertension, atrial fibrillation and better management of valvular heart disease. The latter is a condition is characterized by damage to one of the four heart valves and may require surgical intervention.

Readings are presented instantly on the built-in LCD matrix screen and in much more detail in the accompanying smartphone app. The Wi-Fi sync means you don’t need your phone in close vicinity.

Monitoring high blood pressure, atrial fibrillation and valvular heart disease with one product is a game changer. You essentially get a complete heart health checkup in 90 seconds.

A pioneer in this area, the French outfit has taken heart health tracking up a notch once again and given the competition something to aim for. For now BPM Core is only available for purchase in Europe. US availability is expected soon.

You can check out our full hands-on review on this link.

Withings*

Withings Scanwatch & Scanwatch 2

Another Withings product that is on this list is Scanwatch. This is the best and more feature-packed health tracking hybrid that you can buy.

The device has a few unique abilities that make it stand out from the crowd. One of these is that it can detect heart health conditions, courtesy of a medical-grade ECG sensor. Press on the crown to commence the reading while resting your hand over one side of the watch. Half a minute later you’ll get your results on watch itself, i.e. whether any irregularities were spotted.

Plus there are the usual fitness tracking sensors along with the ability to take SpO2 measurements. And all of this is coupled with exceptional battery life of up to a month.

ScanWatch is for those looking for something that doesn’t look like a fitness tracker yet performs the functionalities of one. We walked away impressed when we did our hands-on review.

Just recently out is ScanWatch 2 – the same great device, but with some new functionality added in. The most notable addition is 24/7 body temperature monitoring.

Amazon | Withings*

Samsung Galaxy Watch 4 & above

Samsung has recently launched the next iteration in the Galaxy watch line. Both carry over tech available ever since generation 4 that allows users to take ECG measurements.

It took Samsung a while to get regulatory approval for its ECG function. It was not a problem obtaining it from South Korean regulatory authorities. But the going got tougher with the US, Europe and other regions’ regulators. The good news is that the company has now secured the necessary regulatory approvals in most countries.

These are fully fledged devices with a plethora of fitness tracking and smart functions. Probably too many to list in this article.

To take an ECG reading you’ll need to place your forearm on a flat surface and rest a fingertip of the other hand on the top button for 30 seconds. The app will then measure both your heart rate and ECG.

In addition to this, the watch is able to measure blood pressure. You do, however, need to calibrate it once in a while with a traditional blood pressure monitor.

Amazon*

Fitbit Sense range & Charge 6

Fitbit is one of the most recognized names in the fitness tracker and smartwatch game. The company has been taken over by Google and this transaction went through last year. But at least for now, its business as usual and we are getting new devices on a regular basis.

A relatively recent addition to Fitbit’s stable of wearables is Charge 6. This is an updated version of its most popular fitness band range. 

Charge 6 packs a lot of great tech. There’s ECG functionality, a 24/7EDA sensor for more detailed stress measurements and a Daily Readiness Score. The last is a single metric that lets you know each morning how prepared you are for the day, i.e. whether you should exercise in the hours ahead or take it easy.

All of these upgrades make Charge 6 a serious health and fitness tracker. In fact it is now right on par with Fitbit Sense 2 as far as these types of features. 

So something for everyone there. If you want a fitness band that measures ECG, go for Charge 6. Sense offers this in a smartwatch package. Which has other benefits that come in the form of a larger display and more smart functionality. Plus there the second generation of Sense which comes with a few incremental upgrades.

Amazon (Charge 6) | Amazon (Sense)*

Frontier X2

Frontier X2 is a bit different from other devices on this list. It comes in the form of a heart rate chest strap.

Its physiological metrics go way beyond your run-of-the-mill heart rate chest strap. The includes things such as Breathing Rate, Step Cadence, Training Load, Body Shock and Heart Rate Variability (HRV). All of this info will allow you to train smarter.

But what really distinguishes Frontier X from the pack is the advanced heart info – namely ECG, cardiac rhythm and cardiac strain. You’ll get real-time vibration alerts if you cross pre-defined thresholds.

As we note in our hands-on review, the ECG functionality can be useful if you are recovering from a heart issue or simply want to check on the health of your ticker. It means Frontier X sits somewhere between a health and sports wearable.

Fourth Frontier (Use code FFGNW25 for 25% discount)*

Wellue Heart Health Monitor

Up next on our list is the innovative Wellue Heart Health Monitor. You can check out our detailed hands-on review.

Comparable to a traditional Holter Monitor, this device offers extra advantages, including enhanced user-friendliness and affordability. It enables you to perform tests at your leisure without having to book doctor appointments, facilitating an initial assessment of arrhythmia and other heart irregularities from the comfort of your home.

A standout feature of this product is its AI ECG analysis, which supplies extensive information about your heart health, such as heart rate, rhythm disturbances, HRV parameters, and specifics of all individual irregularities. The accompanying PC and Mac software offers a comprehensive understanding of these metrics.

While the Wellue Heart Health Monitor may not be necessary for those without known heart issues, it is recommended for individuals with pre-existing conditions or those who desire an extra method to monitor their family’s health. It provides a handy means of tracking your heart rhythm for extended periods, allowing you to detect potential issues whenever needed.

Wellue (use coupon GW10 for a 10% discount)*

Garmin Venu 2 Plus, Venu 3, Fenix 7 Pro and Epix 2 Pro

Garmin has introduced the functionality of capturing ECG readings for the first time on the Venu 2 Plus. More recently this was expanded to Venu 3, Fenix 7 Pro and Epix 2 Pro.

To perform a measurement, simply launch the ECG app and place the fingers of your hand on the bezel. After waiting for 30 seconds, the reading will be completed. The watch is capable of identifying and categorising atrial fibrillation and informing you if your heart is in a normal sinus rhythm.

Now, let’s be clear: your Garmin watch isn’t a certified medical device. It won’t diagnose or treat you, but it can certainly give you some food for thought when you next chat with your healthcare provider.

Why Fitbit matters in the wearable tech landscape

The rise of Fitbit in the field of wearable technology has been nothing short of amazing. The 2007-founded business is frequently recognised as a pioneer in the field of activity trackers.

The San Francisco-based outfit launched its first device, the Fitbit Classic, in 2009, which was a game-changer in the way it allowed users to monitor their physical activities. Unlike traditional pedometers, the Fitbit Classic offered a more comprehensive set of features, including tracking steps, distance, and calories burned, all while syncing data to a computer. This was a significant departure from the limited capabilities of existing health tracking devices at the time.

Fitbit has expanded its product lineup by innovating continuously over the years. Characterised by long battery life, they include smartwatches, sleep trackers, and even devices with heart rate monitoring capabilities. Its early entry and consistent innovation in the market have set industry standards and have made it a reference point in discussions about wearable health technology.

Within the market for wearable technology, Fitbit has successfully carved out a sizable niche. Whether you’re a beginner in fitness or an experienced athlete, its selection of devices has something for you.

Google acquisition – a significant milestone

Fitbit’s acquisition by Google in January 2021 represented a pivotal turning point in the history of the wearables company. In the health and fitness tracking market, where the tech giant had previously lagged behind rivals like Apple and Samsung, this move was seen as its strategic entry.

Essential reading: Top fitness trackers and health gadgets

The deal, which was worth about $2.1 billion, gave Google access to Fitbit’s extensive user database and cutting-edge health monitoring algorithms in addition to giving it a well-known brand in the health tracking industry. Although the agreement raised some privacy and antitrust concerns, it also created new opportunities for integrating Fitbit’s hardware with Google’s software, including its Google Assistant and Google Health services. The merger is expected to accelerate innovation and offer users more comprehensive health and wellness features in future Fitbit devices.

For now it seems business as usual. Fitbit is still churning out devices, the change being that the search giant has joined it with its Google Pixel Watch – which is now on its second generation. That timepiece aims to eat into the market share of well-known gadgets like the Apple Watch.

How Fitbit trackers work: Features and functionalities

If you’ve ever wondered how a small device strapped to your wrist can provide such a wealth of information about your health, you’re about to find out. Fitbit trackers are equipped with an array of sensors and algorithms designed to monitor various aspects of your physical well-being. 

It’s important to note, you can’t use a Fitbit device on its own. It needs to be used in conjunction with the Fitbit app. That software sits on your Android or iOS phone. The stats from the device on your wrist sync to the smartphone via Bluetooth or WiFi. As this information sits in the cloud, you can also access it from the company’s website dashboard.

Here’s a breakdown of some of the key features and functionalities that make Fitbit a comprehensive health tracking tool. The most complex devices go beyond these and measure advanced stats such as stress levels, blood oxygen, recovery status, skin temperature and even ECG. But in this article, we are talking about the basics.

Motion sensing

At the core of any Fitbit device is its ability to track motion. Utilizing a 3-axis accelerometer, Fitbit devices can measure your movements in every direction. This data is then processed to calculate the number of steps you’ve taken, along with the distance you’ve traveled. Some devices also have an altimeter which allows them to count the floors you’ve climbed.

Caloric expenditure

Fitbit goes beyond just tracking movement; it also estimates how many calories you’ve burned throughout the day. By combining motion data with personal information like age, weight, and height, Fitbit provides a picture of your caloric expenditure.

Heart rate monitoring

All of the recent crop of Fitbit models come with built-in optical heart rate monitors. These sensors use photoplethysmography to measure the volume of blood flowing through your wrist, thereby calculating your heart rate. This feature is invaluable for assessing your cardiovascular health and optimizing your workouts. Often, the sensor is also used to estimate your blood oxygen levels.

Sleep tracking

Understanding the quality of your sleep is another area where Fitbit excels. Using a combination of motion sensing and heart rate monitoring, Fitbit devices can analyze your sleep cycles, including the time spent in light, deep, and REM sleep. This data is crucial for identifying sleep patterns and potential issues. Fitbit devices will even track naps.

GPS functionality

Some Fitbit models come with built-in GPS or connected GPS features. This is particularly useful for outdoor activities like running or cycling, where you may want to track your route, distance, and pace in real-time.

Smartphone notifications

While Fitbit’s primary focus is on health and fitness, many models offer smart notifications as well. These include call, text, and calendar alerts, making it easier for you to stay connected without constantly checking your phone.

Contactless payments

NFC (Near Field Communication) technology in Fitbit devices serves as the backbone for Fitbit Pay, allowing users to make secure, contactless payments right from their wrist. This feature, on some devices, integrates with Google Wallet. Thus offering an added layer of convenience. By simply holding your Fitbit near a compatible payment terminal, you can complete transactions without reaching for your phone or wallet.

Water resistance

Most Fitbit devices are water-resistant to some extent, allowing you to track activities like swimming. Previously, such models were few and far between. But now it has become standard. However, it’s essential to check the specific water resistance rating of your model before taking the plunge.

How accurate is Fitbit?

When it comes to health and fitness tracking, accuracy is a critical factor. After all, the insights you gain from your device can directly influence your lifestyle choices and health goals. Fitbit, being a pioneer in the wearable tech industry, has invested heavily in ensuring its devices offer reliable data. However, it’s essential to understand the limitations and variables that can affect the accuracy of these metrics.

Step counting

Fitbit’s step-counting feature is generally reliable, thanks to its advanced 3-axis accelerometer. However, the device may sometimes misinterpret other hand movements as steps. It’s advisable to cross-reference your daily step count with another tracking method if extreme accuracy is required.

Caloric expenditure

Although Fitbit provides a reasonable estimate of calories burned, it’s not 100% accurate. As mentioned, the device uses an algorithm that combines your motion data with personal information like age, weight, and height. External factors like metabolism rate, which Fitbit doesn’t account for, can also influence caloric burn.

Heart rate monitoring

Fitbit’s optical heart rate monitors use photoplethysmography to measure blood flow. While generally accurate for steady-state activities like jogging, the readings may be less reliable during high-intensity interval training or activities that involve significant wrist movement.

Sleep tracking

The introduction of sleep tracking features began with the Fitbit Ultra in 2011. Initially providing basic insights into sleep duration and patterns, Fitbit’s technology has evolved to incorporate sleep stages, sleep score, and other advanced metrics. The company’s sleep tracking is among its more accurate features, as indicated by these studies. However, it’s worth noting that these types of readings are not medical-grade and should not replace professional medical advice.

GPS accuracy

For models with built-in or connected GPS, the location tracking is usually accurate within a small margin of error. However, the accuracy can be affected by environmental factors like tall buildings or dense foliage.

Fitbit free vs premium

Fitbit offers both free and Premium subscription options, each catering to different user needs and expectations. The free version provides a solid foundation for health and fitness tracking, offering features like step counting, sleep analysis, and basic heart rate monitoring. In fact, for most people the free version will suffice. You’ll also get access to exercise summaries and can participate in challenges with friends, making it a robust choice for those who want essential tracking capabilities without any financial commitment.

On the other hand, Fitbit Premium takes your health tracking to the next level. For a monthly or annual fee, you gain access to a host of advanced features, including personalised insights, guided programs, longer trend analytics, and even one-on-one consultations with health coaches. If you’re looking for a more comprehensive and personalized health tracking experience, the Premium subscription is worth considering. It currently runs at $9.99 each month (or $79.99 for an annual subscription).
