The sounds are high quality. I assume theyre on some kind of loop but if so youd never know. I use it every night. The timer function is nice too. Id love to be able to time it to start in the morning (bird song, maybe?) but you can time it to stop the sleep-associated sounds to stop when you want to wake up. By far the best app Ive tried.
