Natural Ambience Sounds

This app works just fine. The interface may be slightly archaic, but the sounds are good with seamless loops. The ads are a bit ridiculous, but there is a paid version with no ads and more sounds.

No timer and it stops if the iOS device sleeps or in the case of an iPad is shut 99% of the reason for this sort of app is to help those with tinnitus get to sleep. This needs a major overhaul to be useful

I purchased the add free version of this app, but would not have done so if I knew it didn't have a timer.
