The big winner in the second Android Developers Challenge (ADC2), SweetDreams, is now available for download.  Designed to allow its users to go to bed without worrying about getting calls in the middle of the night, SweetDreams, packs a ton of options into a relatively small (2MB) app.

Tell SweetDreams what time you go to bed and when you typically wake up and the rest is downhill. Customization features include toggling WiFi, Bluetooth, turning off the screen, notifications, and more. Not only does this work based on your preset time, but location also plays into SweetDreams. Users can also set specific spots on the map for when they want the app to be activated. Another cool feature is the ability to adjust motion and sound settings. Want your phone to wake up as soon as you grab it off the night stand? Presto! Likewise, you can also have your phone woken up by the alarm clock or rooster outside.

There are plenty of options available to customize SweetDreams around your preferences. It’s pretty easy to see why this app was a winner in the Android Developers Challenge.
