How is my SleepScore calculated?
Your nightly SleepScore measures the quality of your sleep against the following criteria:

  • Total time asleep  
  • Time it takes to fall asleep 
  • Time spent in light sleep 
  • Time spent in deep sleep 
  • Time spent in REM sleep 
  • Number of times you woke up at night 

Our app’s algorithm compares your data to known averages for your gender and age, which have been developed based on in-depth research and more than 6 million nights of sleep studies. The average SleepScore is 78. However, within 14 nights of using our app, 60% of users fall asleep faster, 44% improve their deep sleep, and 21% sleep for longer — all factors that help boost your SleepScore over time.
