An innovative health smartwatch with ECG app, SpO2 & stress management.

Lessen your stress

The on-wrist EDA Scan app detects electrodermal activity, which may indicate your body’s response to stress. You can use the Fitbit app to track trends over time, reflect on your mood and try new mindfulness tools. Understanding stress is clearer with your daily Stress Management Score, which comes with a helpful breakdown for Premium members.

For the muscle that moves you

Use the on-wrist ECG app to assess your heart for atrial fibrillation (AFib), a common heart rhythm irregularity. Plus, stay informed with heart rate notifications when Sense detects that your heart rate is above or below your threshold

Take health to the next degree

Skin temperature tells a story about your body. Sense has an on-wrist skin temperature sensor to track your variation each night and show if it varies from your usual range, so you can identify changes in your trends over time.

A new way to see wellness

Track your average nightly blood oxygen saturation level, or SpO2, on your wrist with an SpO2 clock face, then view trends over the past week in the Fitbit app.

6 months of health insights

Sense unlocks a free 6-month trial for new Premium users so you can optimize your well-being: see your SpO2, breathing rate and heart rate variability trends over the past month in the Health Metrics dashboard, plus advanced mindfulness & stress management tools, deeper sleep analysis, personalized insights and more.

Boost your energy with better rest

Track your time in light, deep and REM sleep, then get a Sleep Score to better understand your ZZZs. And use the Smart Wake alarm to wake up during the optimal stage of sleep and be ready to take on your day.
