sleep score
Rest quality rating
A sleep score is a numerical rating, typically out of 100, that quantifies sleep quality based on factors like duration, interruptions, and time spent in different sleep stages.
Fitness trackers and sleep apps generate these scores: My sleep score was only 65 last night—I kept waking up.
The metric gamifies rest, encouraging users to optimize their sleep habits.
