This is a great app. Honestly I use it all the time. When I was in college I used it as a study aid (white noise is helpful for focusing) as well as when I fall asleep. The variety of sounds and the ability to customize your sounds is really useful for me. I turn the "rain sounds" down and turn up the thunder when I study, but turn up the rain again when i sleep. So lovely.
