All-day Stress Detection

Recognize stressful events, manage them and move on with our new continuous EDA sensor on Sense 2. It helps detect stress events so you can start to see how and when your stress is triggered. Use of the cEDA sensor may affect battery life.

Stress Management Score

Get a handle on your stress. Higher score? You're showing fewer signs of stress. Lower score? Time to find better balance--try a meditation or go for a walk.

Sleep Profile

It's easier to get better sleep when you know what kind of sleeper you are. Find out whether your sleep mirrors a deep-sleep bear, a slow-to-sleep tortoise or one of our other Sleep Animals, then learn what habits best to support your profile.

Sleep Stages & Sleep Score

Learn about the quality of your previous night's sleep with a personalized Sleep Score. With Premium, see a breakdown of time in light, deep & REM sleep to see what's impacting your rest.

Fitbit ECG App & Irregular Heart Rhythm Notifications

There are two ways to uncover Afib, right at your fingertips. With the ECG app, you can take an assessment on demand. Plus, use irregular heart rhythm notifications to look for signs of Afib while you're still or sleeping.

High & Low Heart Rate Notifications

Your heart rate is a key indicator of health, so Sense 2 keeps you informed when it's above or below your set resting threshold.

Daily Readiness Score

Enhance your workout routine with a Daily Readiness score that reveals if you're ready to push or should focus on recovery.

Active Zone Minutes

Get the results you want from every workout. Active Zone Minutes uses your heart rate to guide you toward your desired intensity level--then helps you get there.

Built-in GPS

See your real-time pace & distance without your phone using built-in GPS during outdoor activity, then see a map of your workout route in the Fitbit app.

40+ Exercise Modes

Sense 2 tracks more exercises than ever--like skiing, golf, stand-up paddle boarding and more--and see all your stats in real time.
