I suffer from chronic insomnia & have tried several apps to help me get to sleep. This one is easy to use & offers a variety of sound options. If I had to point out one flaw, it would be that there is no quick play option. You must set an alarm for the sleep features. Once it is set up, you can just play, so not a big issue. I set up several choices to solve that problem. Definitely worth the money spent.
