Sleep as Android is an alarm clock application that goes above and beyond regular mobile phone alarm clocks. To start with, it comes with a function for a gradual wake-up that increases the volume progressively to wake you up more gently; but it includes way more than just that.

Among its most interesting features you'll find a graph that shows you how much time you've slept in the last few days, including how much deep sleep and superficial sleep. Plus, it shows you if you’re sleeping more or less than what is recommended for you and how you should modify your habits.

Other options included in the app are: solving math problems as a way to stop the alarm so you prove you're really awake, or lullabies that help you fall asleep and which automatically turn off after a few minutes.

Sleep as Android is a sleep complement tool that includes features which are far superior to most traditional alarm clocks.
