See your health metrics all in one place

Get a closer look at your oxygen saturation (SpO2), skin temperature variations and more, all on your Health Metrics dashboard.

Learn about your skin temperature variations

Tracking skin temperature variation can be a helpful way to identify potential changes in your body—like fever or ovulation. Automatically measure your skin temperature variation and see trends in the app. Plus, Sense 2 and Sense users can even see minute-by-minute variation.**

Know your heart on another level

The heart rate tracking feature on your Fitbit watch or tracker automatically measures the variation of time between each heartbeat—known as heart rate variability (HRV)—along with your resting heart rate and sends your stats to the Fitbit app. Then, you can use the Health Metrics dashboard to view any significant changes that can help you understand if your body is showing potential signs of stress, illness or fatigue.
