Sleep Cycle is an intelligent alarm clock that analyzes your sleep and wakes you in the lightest sleep phase – the natural way to wake up feeling rested and relaxed. Sleep Cycle monitors your movement during sleep using the extremely sensitive accelerometer in your phone. Then it finds the optimal time to wake you up during a 30 minute window that ends at your set alarm time.

Key features include:

  • Detailed sleep statistics and sleep graphs for every night
  • Choose from 15 carefully selected, high quality, alarm melodies or use your own music.
  • Customizable wake up window. From instant (regular alarm clock) up to 90 minutes
  • Sleep notes – see how events such as drinking coffee, eating too much or having a stressful day affect your sleep quality
