About the Fitbit Sense 2 Smartwatch
Fitbit Sense 2 is a health-focused smartwatch for people who want a clearer picture of their stress, sleep and overall wellness. It tracks your heart rate around the clock along with steps, calories and activity, and it works with both Android phones and iPhones.
Stress management is a big part of its appeal. A continuous EDA sensor watches for physical signs of stress and reminds you to check in, so you can respond with a breathing session or some exercise. Sleep tools look at the quality of your rest and point to areas to improve, while blood oxygen (SpO2), heart rate variability and skin temperature readings help you notice changes over time. The ECG app and irregular heart rhythm notifications can also check for signs of atrial fibrillation.
The 1.58-inch AMOLED screen offers an always-on mode and sits under Gorilla Glass 3. Built-in GPS maps outdoor routes, Google Wallet and Google Maps help when you're out, and the battery is rated for up to 6 days. A 6-month Fitbit Premium membership is included for deeper insights.
What reviewers say
Reviewers see the Sense 2 as a comfortable, easy-to-use health tracker with long battery life and a broad set of wellness sensors, including ECG, stress and skin temperature tracking. The common criticisms are that it's limited as a smartwatch, with no third-party apps or music controls, that workout heart-rate readings can be inconsistent, and that the deepest insights sit behind a Fitbit Premium subscription.
