I use this app every night. It freaks out sometimes, and I have to do a timer based setting rather than a time to wake up, but I deal with it.
My biggest complaint is the absolutely kluge White Noise Market process to get sounds that have been "downloaded" to actually BE in White Noise! I download them from Market. I go into White Noise. They are not in my list! I go do downloads, which brings me back to Market, I click Open at which point Im still in the Market and the sounds STILL are not downloaded or uploaded into White Noise! I dont know if it is just me, but it is beyond frustrating. I still have no clue what random set of actions finally get the sounds available to me in White Noise.
My other comment is that the clips on the Market are very tinny (NOT Tiny) and do not give a good representation of the actual sounds. Ive noticed it is extreme on ones I have downloaded (finally got into White Noise to hear) and they are much better quality without the cheap tin speaker sounds.
