These apps get mixed reviews because the alarm is supposed to wake you during your light cycle and people are generally stupid so there are reviews stating that they were late for work or woke up way too early.
It could be something to try out on days off or something.

I have been trying one of these for Android called sleepbot. You leave your phone on the mattress near your head and it uses the accelerometer to measure your movements during the night to track your sleep cycles. If you set an alarm it will try to wake you up within a half hour range of the time you set at a point where you are not in deep sleep. It's been surprisingly effective for me so far.
It also provides you with charts of your movements during the night and a bunch of other tools that are neat too. One unexpectedly cool tool for me is that when you wake up it asks you to rate your sleep and you can insert a comment, which I have been using to make records of the dreams I've been having just before I wake up. Super heroes play a surprisingly large role in my subconscious thinking apparently and it is cool just to have a record of this.
