Wake Up Time
I love this app. It is not hard to figure out, super easy to set, and the sound choices are pretty darn useful. I like waking up to the Forest with bird call echoing in the early morn. I set my Iphone 5s to go off 5 minutes after Wake Up Time to hear a loud woodpecker who is determined to get my attention.
