"Nature Sound" - Fall asleep faster and sleep better!
This application has 4 sounds, including:
- Beach
- Forest
- Water flow
- Rain

First you choose the sound, you then set the timer and put your app in background or turn off the screen. At the end of the time, the sound fades gently and the application closes by itself. So you do not have to worry about closing the app if you fall asleep.
