Don't waste your money. In addition to the previous comment, the program turns off sounds when your iPhone goes into sleep mode. And contrary to the program description, it goes to sleep when your iPhone is on the charger. Basically you get sounds for less than a minute, then the sounds stop. It's a joke. If you plan to use environmental sounds to help you sleep, better look elsewhere. Wish I could give it no stars. It should be pulled from the Apps store. Are there any internal controls to prevent bogus apps from listing in the store. I'd like my money back too. Ripped off.
