[iOS] Free - Quiety: Sleep. Nature Sounds. (was $1.49) - Apple App Store

Another useful and pretty highly rated app (4.7 out of 5) that will help you sleep by providing various calming sounds. It does have a subscription model if you want ALL content but it is not necessary to use the app - you just do not have access to all content but it still works fine.
