Relaxing sounds with a timer for a great nights sleep

What I particularly like about this app is that there are numerous and varied choices of relaxing sounds + a timer so that I can go to sleep listening to thunderstorms, for example. I set the timer for however long I want, and Im not concerned about the sound interfering with the alarm on my iPhone or iPad because the sound will have stopped several hours before I need to wake up.
