Fitbit Sense Advanced Health Watch

Better understand how your body is handling stress with a daily score.

The on-wrist EDA Scan app detects electrodermal activity—which may indicate your body’s response to stress—and reveals a graph in the Fitbit app to illuminate it.

With a compatible ECG app right on your wrist, assess your heart for atrial fibrillation—a heart rhythm irregularity—and share the results with your doctor.The Fitbit ECG app is only available in select countries. Not intended for use by people under 22 years old.

With an all-new multipath sensor, Sense delivers PurePulse 2.0—Fitbit’s 24/7 continuous heart rate tracking for exercise, sleep tracking and everything in between.

Track heart rate variability (HRV)—the variation of time between each heartbeat— to see if your body is showing potential signs of stress, illness or fatigue. View your nightly average and trends over the past week in the Health Metrics dashboard.‡

See your time in light, deep and REM sleep and get a daily Sleep Score in the Fitbit app and on your wrist to better understand your sleep quality each night.

During outdoor runs, rides, hikes and more, use built-in GPS to see your pace and distance on Sense, then see a map of your workout in the Fitbit app.

During workouts, get real-time stats on screen to see whether you’re in fat burn, cardio or peak zone, so you can dial the effort up or down according to your goals.

Sense is water resistant to 50 meters, which means you’re free to track laps in the pool, wear it at the beach and beyond.

Track all-day activity like steps, distance, floors climbed, active minutes and calories burned to show how every part of your day gets you closer to your goals.
