Not worth it
I really wish the App Store let you download an app for 24hrs to test it before you actually bought it... The fan sounds are awful, most sound like anything but a fan. Car mufflers, lawn mowers, squeaky wheels, you name it. Oh, and despite setting the timer, and trying everything else I could find in the settings, the sounds cut off as soon as your phone locks. Its crap, plain and simple.
