Great app for naps!
I typically sleep with an air purifier on, mainly for the noise it puts out. I use the iHome Zen app when I have a chance to take a mid-day nap when Im between clients.
I didnt give 5 stars, because I feel there could be more sounds that could be made available, but despite that, its a great app!
