BetterSleep: Sleep and Meditation 20.2.2

BetterSleep is an excellent Android application containing a huge variety of wildlife sounds and melodies. You can compose them at your discretion, setting your own volume level for each sound. For example, you can compose the sound of the surf, the cries of seagulls and a quiet piano melody. Or the noise of the forest, the singing of birds and a fine drizzling rain.

Composed mixes of melodies can be saved to play them quickly. The application allows you to set a timer to turn off the melody in order to turn on relaxing sounds and fall asleep to them, and the application will turn off playback on its own.
