Best fitness band for the average person


Fitbit Charge 4

Fitbit Charge 4 was launched earlier this year. The much anticipated upgrade to the company’s best selling activity band is here. It takes across everything from the previous generation, and slaps on some worthy upgrades.

The sleek looking fitness band has been our favourite for a couple of years now. So until something better comes along, the new version is our choice for the average person who does the occasional run here and there – particularly as the price has not changed.

The device has pretty much everything you need for 24/7 activity tracking. The main addition with the fourth generation is built-in GPS. Something runners and cyclists will appreciate, the functionality will come in handy with many of the 20 or so exercise modes.

The other change worth mentioning is that NFC comes as default now. Previously it was only available for the special edition of the device.

The remaining specs are largely identical as the predecessor version so you still get the grayscale OLED display and identical design, fitness and sleep tracking smarts and PulseOx. The 7 day battery is no different, as is the 5 ATM water-resistance. With GPS switched on, battery life falls to a respectable 5 hours.

Last but certainly not least are the smart features. These have progressed so much that they are starting to blend the line between fitness tracker and smartwatch. Charge 4 comes with call, calendar, text and smartphone app notifications. There is a host of Fitbit and third-party apps, too, as well as Spotify control.

Runner up # 1

Fitbit Luxe

A new addition to Fitbit’s range, this one comes in the form of a discreet band but it packs most of the health and fitness tracking functionality you can find in high-spec smartwatches.

In fact, the thing is pretty much on par with Charge 4 as far as health and fitness stats. The only thing that is missing is built-in GPS and an altimeter for counting floors. Also, the battery life is shorter.

luxe might be fitbit most elegant fitness tracker yet 5 - Best fitness trackers and health gadgets for 2021

But what works in its advantage is the small form-factor and beautiful AMOLED display. There is no price difference between the two so the decision comes down to your preferred design and whether you need built-in GPS or can do with Connected GPS.


Runner up # 2

Garmin Vivosmart 4

Vivosmart 4 is another great option if you don’t mind the small screen. In additional to all the usual fitness tracking smarts, the fourth generation device comes with a blood oxygen sensor and it keeps tabs on your body’s energy reserves.

The oxygen saturation feature measures your oxygen levels at night, allowing you to better understand your sleep quality. This can potentially be used to identify sleep conditions such as apnea, although Garmin will not diagnose these. You can also check your readings on demand during the day.

The other novel feature is what Garmin calls Body Battery energy monitoring. This uses a combination of stress, heart rate variability (HRV), sleep and activity data to let you know when to push hard, when to rest.

The other features are fairly standard include the usual step, distance, calories, floors, heart rate and advanced sleep tracking. Like many other Garmin wearables Vivosmart 4 will also keep tabs on your stress, VO2 Max, reps and sets in the gym. No built-in GPS, but there is Connected GPS thanks to a recent software update.

The Forerunner 935 (and 945) is a fully featured running and triathlon GPS sports watch. You will find the usual Elevate wrist-based heart rate for 24/7 heart rate monitoring, and GPS and GLONASS coverage. Additionally, the wearable sports a barometer, altimeter, and a compass.

Essential reading: Gone for a run – top GPS watches for running and training

Where the watch stands out most though, is in its detailed analysis of performance. According to Garmin, the Forerunner aggregates past training results and then uses that data to evaluate the amount of effort users exert during fitness sessions, i.e. if you are slacking off or overdoing it. It does this through two new additional metrics, training load and training status.

Training load looks at users’ exercise activity over the last seven days and compares it to the optimal range for your fitness and recent training history. Training status does the same thing with a more short-term view, and lets you know if you’re training productively, peaking or overreaching. Additionally, the training effect metric tracks and reviews the aerobic and anaerobic benefit of a training session. There are also other advanced dynamics for running, cycling and swimming, including FTP, VO2 max, cadence and others.

For those that want the very best, Garmin also sells the Forerunner 945. It has all the great features of its predecessor, plus on-board storage for music, Garmin Pay, a pulse oximeter and lots of new performance metrics.

Best smart blood pressure monitor

Withings BPM Core

Honored with a CES Innovation Award, Withings Core functions as a BPM, ECG and digital stethoscope. ECG is used to identify atrial fibrillation (AFib), a serious form of irregular heart rhythm that can lead to heart failure and is a major risk for stroke. The digital stethoscope can provide early detection of valvular heart disease. The condition is characterized by damage to one of the four heart valves and may require surgical intervention.

withings bpm core 300x272 - Best fitness trackers and health gadgets for 2021 The ability to monitor all three conditions (high blood pressure, atrial fibrillation and valvular heart disease), with one product definitely sounds like a game changer. You’ll essentially get a complete heart health checkup in 90 seconds.

For now BPM Core is only available for purchase in Europe. US availability is expected later this year. You can check out our full hands-on review on this link.



Omron is one of the most established brands on the home BPM market. Its EVOLV device is a sleek looking one-piece monitor which has no tabletop unit, no tubes and no wires. Because of this the product is highly portable and easy to operate.

Users wrap the entire unit around their upper arm and the blood pressure reading is displayed in bold numbers right on the face of the device. EVOLV provides you with a complete view of your blood pressure with systolic, diastolic and pulse readings. It also detects the appearance of irregular heartbeats during measurement and gives a warning signal with readings.

This is BPM that you can use it completely independently of your smartphone. All you are required to do to take a reading is press one button.

With this device Omron has married their accurate technology with connectivity. In our hands-on review, we found it to be accurate, and the operation to be very smooth, fast and noiseless.

Withings Sleep Analyzer

Withings Sleep Analyzer slips under the mattress from where it tracks all aspects of your nightly (and daily) rest. The company says after 3 days of use, more than a half of users increase their amount of sleep by an average of 48 minutes per night for the next 3 nights. Not bad, as most people are chronically sleep deprived.

The thing lies incognito under your mattress with no buttons to push or need to charge. Jump into bed, and go to sleep. This is exactly what you want – a no hassle tracker that you forget is even there.

The device captures a wealth of stats. Everything from sleep cycles, to interruptions, sleep heart rate, snoring, breathing disturbances and even sleep apnea – it’s all there. In our review we found that it does this accurately even though it lies under a thick mattress. The data it collects automatically makes its way to the app on your phone so is ready to be viewed in the morning.
