This tracker measures stress. Sort of.

Very good battery life (up to a week). Beautiful screen. Easy-to-navigate app and easily customizable. Works with Google Assistant as well as Alexa. Fitbit Premium still rules. It can measure blood oxygen (SpO2) levels and electrodermal activity for stress. Sensors are accurate.

New SpO2 and stress-management tools are less helpful than they sound. Optical O2 sensors bug out occasionally. Too many weird operational hiccups for a premium-priced tracker.

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

When Fitbit announced the $329.95 Sense last month, it was being hyped as the company’s most-thorough health tracking device yet. With new features in the form of stress management (with electrodermal activity monitoring), skin temperature, oxygen saturation while you sleep, and an upcoming Food and...

Sleek design; Bright; colorful screen; Intuitive interface; A ton of granular metrics; including SpO2; heart rate variability; breath rate; skin temp; and EDA; Nice integration with mindfulness training

Lots of bugs and performance hiccups; Solid-state button is fiddly; Some things just don’t feel as fully integrated as they could be; Battery life is cut in half if you turn the display to always-on mode

It's been three years since I first tested the Fibit Ionic and while it was a solid fitness watch, it didn't do well with consistently functioning as a GPS sports watch. For the past couple of weeks I've been testing Fitbit's latest watch with GPS, the Fitbit Sense .

Superb fit; finish; and design; Bright and clear AMOLED display; Lightweight and comfortable for 24/7 wear; Extensive health tracking capability; Smart alarm; Various health scores for understanding progress

No support for offline Spotify music; Basic data for exercise tracking; Swipes on the display don't always register; Solid state button is not as reliable as a physical button

The Fitbit Sense is a comprehensive health-tracking machine with basic smartwatch features and a new navigation system that can be difficult to master. It offers more wellness tools than Apple and Samsung at a cheaper price, and it’s especially great for people who don’t mind wearing a watch to bed...

Comprehensive health tracking tools; Bright and sharp display

Buttonless design requires learning; Somewhat sluggish performance

There’s no question Fitbit has packed in ‘all the sensors’ to the Fitbit Sense. The challenge is whether or not all that data is usable and actionable. And at this point I’m just not seeing that occurring yet.

Software kinks aside, the Fitbit Sense is a great smartwatch at a solid price.

Great design; Excellent health tracking features; Solid display

Sometimes frustrating app; Battery life could be better; Charging cable is too short

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

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...

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...

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

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