Advanced Sleep Tracking
Automatically tracks time spent in light, deep, and REM sleep stages each night. The Fitbit app provides a Sleep Score each morning summarizing your sleep quality, along with personalized insights to help you improve your rest over time.

Stress Management Score
Using heart rate variability and activity data, the Inspire 3 calculates a daily Stress Management Score that helps you understand how your body is responding to physical and emotional stressors – directly relevant to sleep quality.
