How does it work?

  • It typically takes the average person around 15 minutes to fall asleep.
  • A good night's sleep involves 5 to 6 full sleep cycles, each lasting about 90 minutes.
  • Waking up in the middle of a cycle can leave you feeling tired and groggy. But waking up between cycles can help you feel refreshed and alert!
  • Sleepytime analyzes your sleep cycles and suggests times to wake up or go to bed so you can wake up feeling refreshed and alert!
