Relax and Sleep
Name: Relax and Sleep
Developer: Mizu Software Solutions
Compatibility: Android 1.5 and up
Relax and Sleep is another application -- suitable for older versions of Android -- which offers ambient sounds for users to listen to. I like this app because of a single setting -- you are able to change separate track volumes with different effects to create a unique melody. For example, if you like lightning, rain and the sea, you can mix it so the lightning is loudest, and waves are in the background.
