Features

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

EDA Scan App
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.

Reflection
Easily log your mood, from very stressed to very calm, on Sense after an EDA Scan session or in the Fitbit app to help you reflect on what makes you feel your best.

Fitbit ECG App
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. FDA review of ECG app pending; only available in U.S. upon clearance. Availability outside the U.S. pending applicable regulatory clearances. Not intended for use by people under 22 years old. See here for additional details.

On-Wrist Skin Temperature Sensor
Sense tracks your skin temperature each night to show how it varies from your personal baseline, so you can be aware of your trends over time.***

Oxygen Saturation (SpO2) Monitoring
Sense tracks SpO2—the level of oxygen in your blood—to help you learn when there may be an indication of important changes in your fitness and wellness. Use the free SpO2 clock face to track your average nightly SpO2 level, then activate Premium to view trends over time.***
