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.

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).

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.

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.

Amazon*

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.

Amazon (links: Forerunner 255, Forerunner 955), Garmin*

Apple Watch

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.

Amazon | Withings*

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.

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).

Why wear a heart rate monitor?

Most people who exercise will tell you they want to lose weight or simply get fitter. Not many people, however, know what their heart rate is, or where it really should be.

This means that often, they are not training in the most efficient way to achieve their goals. The only way to actually know how many calories you’re burning while you’re exercising is to have a heart rate monitor that is consistently hooked up. All top athlete’s heart rate train, as they know this will help them to reach their top potential in the shortest amount of time possible.

Your body has five heart rate zones. Which zone you spend most of the workout in depends on your goal. For fat burn you want to go for zone 2, to build-up endurance zone 3, while zones 4 and 5 are for hard-core training. Typically you can spend very little time in the high zones.

Essential reading: Heart rate zone training with wearables

In simple English, this means that if you want to burn calories and burn fat drop your pace a bit. If you want to build up speed go for a quicker pace. You can read in detail about heart rate zone training on this link.

Types of heart rate monitors: watch, chest strap, armband

A heart rate chest strap detects your pulse electronically and sends that data to a receiver, such as a smartphone or a wrist-worn tracker. This is similar to what you can see in hospitals with patients who have sensors strapped to their chest. These type of monitors tend to be highly accurate.

The same is the case for heart rate rate trackers that you slip on to your upper or lower arm. This have only started to become available of late. But they have the advantage over chest straps in that they are more comfortable and much more easier to put on.

Fitness trackers, such as those made by Fitbit, Apple or Garmin, monitor your heart rate from the wrist. They operate by shining a light, which is then reflected by blood vessels passing through your veins. When your heart pumps, the blood moves through your veins at a quicker rate, causing less light to be reflected back. The wrist worn device then calculates your heart rate using an algorithm.

While this is a more convenient way of tracking your ticker, the accuracy can never compare with chest or arm band style monitor. If you are very serious about heart rate training, a chest or armband monitor is the way to go.

Heart rate chest strap vs wrist: the difference in accuracy quantified

A recent study has quantified the difference in accuracy between heart rate chest straps and wrist based heart rate monitors. It was published by the Cleveland Clinic in Cardiovascular Diagnosis & Therapy.

The study recruited 50 healthy, athletic adults (34 men, 16 women) with a mean age of 29. They all ran on a treadmill for 12 minutes with a three lead ECG and Polar H7 chest strap monitor and two randomly assigned, commercially available, wrist-based heart rate monitors. One was warn on each wrist. These included the Apple Watch Series 3, Fitbit Ionic, Tom Tom Spark 3 and Garmin Vivosmart HR. The speed of the treadmill was increased gradually, starting from 4 miles per hour to a final 2-minute stretch at 9 miles per hour (at zero incline).

The researchers then pitted the results from different heart rate monitors against the ECG. Unsurprisingly, the Polar H7 chest strap had the greatest correlation coefficient with the ECG (r_c=98). This was the case at all paces. The Apple Watch was next (r_c=96), followed by the other three wrist-based heart rate monitors which all had a similar level of agreement (r_c=89). Each of the four watches was assessed a total of 25 times.

Whats more the study found that as runners went faster, accuracy of wrist monitors tended to suffer. The Apple Watch Series 3 fared best, once again. At 9 mph it was only off by 1.5 bpm, as compared to nearly 3 bpm for the Garmin.

However, at rest the difference was negligible. This would suggest that it’s perfectly okay to use such devices to monitor heart rate at low intensity activity and to keep tabs on resting heart rate which is perhaps one of the most important indicators of health and fitness of an individual.

This was not the first such research by Cleveland Clinic. An earlier study looked at accuracy of wrist-based wearables while participants were using a treadmill at moderate speed (up to 6 mph). The agreement with ECG was as follows: Polar H7 chest strap (0.99), Apple Watch (0.93), Garmin Forerunner 235 (0.92), Tom Tom Spark Cardio (0.88) and Fitbit Blaze (0.76).

It’s worth noting, these conditions do not exactly replicate running outdoors or on a different terrain. Furthermore, because they are running on a treadmill participants were in some instances recorded when gripping the treadmill handrail.

So what can we take from all of this?

While fitness trackers and smartwatches provide a more convenient way of tracking your ticker, the accuracy can never compare with chest or arm band style monitor. Particularly for high intensity workouts. 

This may change in the future as accuracy of smartwatch and fitness band heart rate monitors improves. But for now we are still not there.

The best heart rate monitor chest straps

To come up with our selection of best heart rate monitors we’ve examined functions and features of each device carefully and thoroughly.

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

Essential reading: Best fitness trackers and health gadgets

Several devices have been released in the last couple of years. We anticipate that in the future, there will be a greater emphasis on better data interpretation, the integration of new sensors. There will also be a gradual shift away from the wrist (think smart shoes, clothes, etc.).

Until we come to a time when these wearables reside inside our body! But that’s another story.

The truth is, not every tracker is for everybody. You’ll find wearables aimed at workout newbies, gym junkies, runners and swimmers. So, how do you find the perfect tracker for your life? Here are some things to consider.

(1) What is your budget? How much money do you want to spend?

Wearables vary greatly in price. But you can now buy devices with a wide range of different features at a very reasonable price. Also, with each subsequent generation of a wearable, the earlier versions are coming down in price. While these devices may not track everything, with some research, you may be able to find one that meets your requirements.

On the low end, you’ll find models such as the Xiaomi Mi Band 7, Fitbit Inspire 3 and more. These wearables offer quite a bit for the money. You could always go for unknown brands. But it is best to go for tried and tested brands as they combine quality hardware with quality software.

If, however, you are interested in fully featured fitness device, you will need to spend a bit more to purchase for example a Fitbit Charge 5 or Luxe, or go for a Garmin activity band. They are a bit more pricey, but you get a more complete fitness and health tracking experience.

At the more expensive end, you’ll find devices that come in the form of a smartwatch. Good examples are the Garmin Vivoactive 4, Fitbit Versa and Sense, the Apple Watch, Samsung Galaxy Watch 5 and plethora of other smartwatches and sports watches that are out there. To help you choose, we’ve put together a handy tech specs comparison tool – choose a few devices and see how they stack up.

(2) What do you want to track? Standard metrics or are you after something more specific?

Most fitness trackers keep tabs on steps, distance, calories and activity. They will also give you a little buzz if you’ve been sedentary for a specific period of time, which is helpful to keep you moving throughout the day. An increasing amount of research points to the dangers of leading a sedentary lifestyle.

The more advanced wearables also include built-in GPS for more precise distance measurement. If your primary activity is walking, hiking, or running, almost any brand will suffice. Not if you spend the majority of your time cycling, using an elliptical, walking on a treadmill, swimming, or mountain climbing. Choose a tracker that can record data for the specific activity or sport that you enjoy the most.

Sleep tracking is another popular feature. Overnight sleep is essential for good health and well-being throughout your life. Wearables provide a wide range of information, from simply monitoring total time to providing details on various stages of sleep such as light, deep, and REM sleep. Furthermore, not all will keep track of your daily naps. Fitbit, for example, will, but Garmin will not. Many devices also have silent alarms that vibrate to wake you up without waking up your partner.

Essential reading: Best devices for advanced sleep monitoring

Aside from these fairly standard metrics, some fitness trackers can monitor a variety of other things. Your heart rate, body temperature, galvanic skin response, and blood oxygen levels are all included. In general, the more tracking features you want, the more you will pay for your device. The future is meaningful analysis of our vitals data.

(3) Does the design appeal to you? This is a matter of personal taste.

Trackers come in a variety of shapes, styles, and sizes. Design is a highly subjective, but crucial, topic. Activity trackers began as bulky and unappealing devices aimed at fitness enthusiasts and technology enthusiasts. The tech community has recognized the significance of creating wearables that are both functional and appealing.

Most fitness trackers are designed to be worn constantly, so you must enjoy having something strapped to your wrist. It is a good idea to try one on before purchasing if you have the opportunity.

In terms of design, we can divide activity trackers into three categories.

The first type of band is a sporty band. These are usually rubberized and have a simple appearance. Fitbits and Garmin activity bands are two excellent examples. The ones that come in the form of a smartwatch are the next category. This includes hybrids that combine the classic looks of analogue watches with cutting-edge technology. The final type of tracker is one that resembles a high-quality analog watch or a piece of jewelry. There aren’t many of those.

At the moment, men are clearly more interested in wearable technology than women. They buy roughly 70% of Fitbit devices, according to the company. This is gradually changing, and an increasing number of trackers are being designed with female fitness enthusiasts in mind.

Whatever wearable device you select, make sure you are completely comfortable with it.

(4) Color display, black and white or no display?

This is again, a subjective topic.

The first point of view is that you want a display to track your progress throughout the day. There are numerous options available, such as a fully featured AMOLED display, a black and white screen, or simply a set of LED lights. Another factor to consider is that larger screen real-estate will typically drain the battery faster. And your purse…

The second point of view is that you’re better off without a display so you don’t become addicted to checking the numbers on your wrist — the device becomes less of a distraction in that case. However, you will be entirely reliant on your smartphone or web interface to track your progress.

We definitely belong to the first camp.

(5) User experience

When it comes to your tracker, you’ll want a unified user experience. There are technical issues to consider, such as setup, charging the device, and storing your data. Does it sync automatically? Is it resistant to water? These are just a few of the questions you should be asking yourself.

You should also consider how simple it is to interact with the tracker you are considering. Some have fully functional touch screens, whereas others are more minimalistic and are activated by tapping the device.

However, wearing a fitness tracker is only half the story. Understanding and utilizing your data to live a healthy life is also critical. Different activity trackers display data in different ways. As a result, it is critical that the smartphone app and any website interface are appealing and simple to use, and that they provide you with the information that you are most interested in.

(6) Keeping it juiced

Regardless of which fitness tracker you choose, eventually you are going to have to take it off to recharge or change the battery. When this is occuring, the device will obviously stop tracking your activity, so you’ll get gaps in data.

Battery life can vary quite a bit. Depending on the tracker you buy, you’ll get anywhere from up to a day or two out of your device (Apple Watch and most WearOS devices) to an average of about a week (most Fitbit and Garmin fitness bands). Some can go longer and a few even have advertised battery life of a month – but that’s with reduced functionality.

Trackers using disposable watch batteries last longer, but they require a replacement every few months to up to a year. They are also slimmer on features. Rechargeable batteries, on the other hand, are built to spec for each device.

As for charging up the batteries, most require nothing more than a standard USB port. Some will charge faster than others, but factor in on at least a few hours for a full refuel.

(7) Built-in GPS or no built-in GPS?

Fitness trackers with built in GPS are a bit more expensive than the more run of the mill variety. If you are a runner, for example, you will want to know every detail about your training sessions. You’ll want to know when you moved the fastest, when you struggled, and what kind of terrain you encountered difficulties with. When you combine built-in GPS with a fitness tracker, you have access to all of this data. A GPS may also be useful if you are concerned about becoming lost.

GPS is useful, but only if you really need it. Some fitness trackers can connect to your smartphone and extract GPS data. This, however, means you’ll need to carry your smartphone with you on those early morning runs. If you walk the same trail every day, then a GPS monitor isn’t going to do all that much for you. If you hit the gym primarily, the results will be entirely uninteresting!

(8) Is it water-resistant? Or swim friendly?

When it comes to buying the right fitness tracker, the characteristic of water-resistance should always be considered.

Essential reading: Explaining water resistance ratings

There are no waterproof wearables available. Waterproof markings on watches and fitness wearables are prohibited by law. This is because a wearable will always begin to leak at a certain level of water pressure. As a result, wearables can only be labeled as water-resistant.

Before entering a shower or swimming pool, always check the markings on your device or the manufacturer’s website. The good news is that good water resistance is gradually becoming an industry standard.

(9) Is there a heart rate monitor? Heart-rate monitors vary greatly too.

A recent study suggests that resting heart rate can be used to predict your longevity. Researchers found that the risk of dying from any illness or health condition raises by around 9% for every 10 bpm. The chance of suffering a fatal heart attack or stroke rises 8%.

Resting heart rate can also be used to assess fatigue levels. If you find that your readings are elevated from their normal average (more than 7 bpm), that could be a sign that you’re not fully recovered from a hard workout. You should then consider taking a few days or a week to allow your body time to recover. Or perhaps you are coming down with an illness.

Most activity trackers these days automatically track your resting heart-rate. They also provide you with a historical record which you can tap into to see how your readings are changing over time.

This type of information is particularly important when it comes to running or cycling. Your body has 5 heart rate zones. Not many people however know what their heart rate is, or where it should really be. This means that often, they are not training in the most efficient way to achieve their goals. All top athlete’s heart rate train, as they know this will help them to reach their top potential in the shortest amount of time possible.

Heart rate sensors are a standard offering for new fitness devices. These work around the clock so there’s nothing for you to do apart from wear the fitness tracker or smartwatch.

Don’t expect perfect heart rate readings, though, from a wrist-based heart rate monitor. Particularly when you engage in high intensity activity. If you are really serious about heart-rate zone training, you will be better off with a chest strap.

(10) Do you want extras such as smart notifications, NFC payments, LTE connectivity, etc…?

The majority of fitness trackers do more than just monitor activity. Some, for example, connect to your smartphone to send you email, text message, or social media notifications. They can also serve as a reminder of important events or calendar appointments. Others facilitate contactless payments.

Then there are smartwatches, which are even better. They provide a more robust experience. The Apple Watch is essentially a miniature computer. Wear OS devices also come with a plethora of apps that can be installed. These are significantly more expensive, so it will come down to what is most important to you.

Do you simply want something that tracks your health and fitness? If you do then go for a fitness band, a hybrid or simple smartwatch. Do you want something that offers lots of smart functionality? Then go for a fully fledged smartwatch – you’ll get the best of both worlds in that case. Finally, there’s a category of watches that can work without your smartphone. These come with built-in cellular ability which typically entails a monthly service charge.
