Good rest matters, and so will Fitbit's Sleep Score in a major Public Preview rework

Fitbit is redesigning Sleep Score in Public Preview to use a broader set of sleep metrics, including duration, Sound Sleep, restfulness, awakenings, and interruptions.

The app will add color-coded breakdowns, while Fitbit Premium users will get Personalized Insights and coach suggestions.

Fitbit says scores may temporarily fluctuate as the new model stabilizes.

If device and app scores don’t match, Fitbit says the app score should be used.
