Best implementation of stress-tracking so far; adds EDA sensor and has FDA-cleared ECG; low and high heart rate notifications; lengthy battery life plus fast charging; adds more advanced health metrics; improved strap design; accurate tracking

Real-time heart rate-tracking was laggy on-wrist; side button is easily triggered accidentally; always-on display zaps battery; screen not as responsive as I'd like

The Fitbit Sense is a fiercely ambitous smartwatch with mixed results. On the one wrist, you can’t help but admire its intention, and really investing your time in the vast amount of health data it stores for you will surely see you rewarded over time. We’re still getting to grips with the stress management stuff, which seems a bit opaque at first, but it’s a good addition to the Fitbit suite. As is a proper ECG. And that battery is excellent. On the other, however, you have a frustratingly temperamental smartwatch that, while nice to both wear and look at, is too slow and too buggy at the time of writing, and Fitbit’s app library is still a bit naff. If only it cared as much about performance as it does your health and wellbeing.

Comfortable to wear ; Nice OLED display; EDA, ECG, SpO2 and a skin temperature sensor make the Sense unrivalled for health features; Apple Watch-embarrassing battery life ;

Seriously buggy and slow; Data overload can be both vague and confusing; Forces you into selecting a certain watchface for SpO2 measurements ; You need Fitbit Premium to maximise it;

The Fitbit Sense is an ambitious smartwatch that seems like a perfect fit for these stressful times, with as much emphasis on mental wellbeing as tracking physical workouts. There's room for improvement on the software side, but if you're interested in practicing mindfulness and making small steps towards a healthier lifestyle, the Sense could be just the tool to help you along the way.

Detailed mood and stress logging; On-board GPS for workouts; Extremely comfortable to wear;

Many tools require Fitbit Premium; Step counts not 100% inaccurate

For all-round physical and mental health tracking, the Sense is the Fitbit with it all.

Stress tracking; Great design and display; Calls from wrist; Fitbit app;

Non-buckle wrist strap; Some metrics for paying Premium subscribers only;

Proactive. Thanks to ECG, heart rate, SpO2 and temperature sensors, Fitbit Sense currently is one of the most advanced wearables in terms of health monitoring. We have taken a close look at this smartwatch and its health functions in our review.

The Fitbit Sense is a solid smartwatch with a good screen, a relatively slim design, two day-plus battery life, solid Google Assistant or Alexa integration and simple smartphone alerts.

Pros: good screen; responsive; slim design; extensive health tracking; ECG; good basic workout tracking; GPS; good activity motivation; Google Assistant/Alexa; solid smartwatch battery life.

Cons: not sustainable; no OOW repair options; proprietary straps; issues with GPS accuracy; no advanced workout tracking; some health-tracking features require additional monthly subscription; short charging cable.

If you're specifically in the market for a watch to help monitor your health - and you're happy to pay the monthly subscription for the extra insights - then the Sense is a really great device with so much data. But if you're in the market for a smartwatch or fitness watch in general, however, the Fitbit Sense is currently outshone by its competitors.

Solid and premium design; Lovely vibrant display; Easy to use; Fitbit app is brilliant; Good accessory collection; Great sleep tracking; Spotify support; Great health features;

Heart-rate sensor slow to respond; Smartphone notifications pointless; No Google Assistant yet; Limited third-party app support; Fitbit Pay support from banks is minimal; Lots of features locked behind Fitbit Premium;

If you're like me, every headache or stuffy nose these days is accompanied by a strong case of COVID-19 paranoia. With its premium Sense smartwatch, Fitbit is giving you many of the features you want and need to monitor your health amid a global pandemic. At $329.95, it's the company's priciest wearable yet, but it packs sensors to measure the amount of oxygen in your blood, as well as changes in your skin temperature, stress level, and heart rhythm, in addition to the robust sleep and fitness tracking features Fitbit is known for. Its selection of downloadable apps pales in comparison with what's available on the Apple Watch, but it offers some welcome smartwatch features including Amazon Alexa support, Pandora and Spotify music controls, and Fitbit Pay mobile payments. If you're in the market for an attractive wearable with long battery life and a focus on health and wellness, the Sense is worth a look. Price, Design, and Specs At $329.95, the Sense is Fitbit's most expensive we...

Fitbit's premium, pricey Sense smartwatch puts a focus on your well-being with the ability to measure and monitor your stress, heart rhythm, skin temperature variation, and blood oxygen saturation.

Attractive design with large, always-on color display; Excellent battery life; Measures blood oxygen level; Features an ECG app; Robust stress management and sleep tracking features; Supports Amazon Alexa, Fitbit Pay, Spotify

Expensive; Touch screen responsiveness could be better; Band release latch can be accidentally triggered; Small third-party app selection

The features I like the most are the health apps and reminders. I am over 70 and need reminders for regular medications and wear sense to bed and check my overnight oxygen levels.
