Sleep Away is a sleep management application that provides two main functions:
Manage your sleep. By letting Sleep Away calculate your sleep cycles, you can either set your alarm to wake up feeling well rested if you go to sleep now, or set a reminder to go to bed at a calculated time, so you wake up when you need to. Sleep Away also lets you set an alarm for a quick power nap.
Listen to white noise. Sleep Away contains a few sounds that you can listen to while you fall asleep. Those currently are: Heater, Rain and Campfire. No need to worry about turning the sound off - the application contains a timer that will automatically shut off the sound after it counts down. You can let your phone sleep and just relax.
