Night Owl

I really like this app. Im using the version, so my "cons" may be resolved in the full version.
Pros: Very reliable; uses a tune to wake me and not a buzz or bell
Cons: Sleep ratings arent necessarily accurate, as there is no way to provide feedback when I wake up during the night. The app rates me as having a great sleep based upon the duration of sleep even if I have awakened during the night. There is no way to log a wake-up other than to turn the alarm off, but then you have to reset it and I dont believe the app recognizes this as an interruption. Overall: All in all it is a great alarm clock!
