The Fitbit Sense delivers on the basics, but it's clear some features need more work....

High-end; premium design Improved quick-release straps (Mostly) accurate GPS and heart rate sensors Skin temp sensor provides useful data Detailed sleep tracking ~6-day battery life

Google Assistant; Bluetooth calling unavailable at launch Bad inductive button SpO2 tracking requires dedicated watch face EDA and ECG sensors needs refining Fitbit OS still needs work

The Fitbit Sense is a big leap forward as a health watch, one that produces a lot of data but perhaps fewer insights. It’s the right device for these strange times. If you’re comfortable with that approach, then there’s a lot to like here.

Health data galore; Stress and mindfulness; We love temperature tracking

The early Fitbits were remarkable for how little you needed to interact with them, but the Sense flips that script. By piling on sensors and features to seemingly compete with Apple, the Sense has added as much complexity as capability.

Nice design and band swapping mechanism; Loaded with next-gen sensors and tracking capabilities; Very good battery life

EDA quick scan takes too long; Fitbit OS is less intuitive and more frustrating than ever; Heavy reliance on Premium makes the price higher than it is

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

The Versa helped Fitbit reverse its fortunes after a long, gradual slide. The company was slow to embrace the smartwatch, and stumbled somewhat out of the gate with the Ionic. But the Versa found a perfect sweet spot that build atop generations of wearable health knowhow, key acquisitions like...

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.
