As long as you’re willing to bring your phone into bed, Sleep as Android can help you catch more Zs. The app measures your muscle movements through the phone’s accelerometer, figuring out when you’re asleep or awake. This allows it to play a lullaby until you’ve fallen asleep, and to wake you up at an optimal time during your sleep cycle. Once the night is over, Sleep as Android provides detailed statistics on how long you’ve slept, and can even record your snores and sleep talk. The app is free to try for two weeks.
