Works great for us!

A reviewer below said it doesnt resume if your kid pushes the home button, but dont worry about that because they must have fixed it because it resumes! It works for us and our two year old sleeps in a bit longer while waiting for it to change to a sun.

We own one of those $30 clocks that does something similar, but that clocks back light was too bright, not to mention the cost of batteries was outrageous! If you have an old iPhone or itouch you could use for it, as we do, its perfect.

In my opinion the extra half hour (and occasional hour our son sleeps in due to this app) pays for the app itself!

Just note that it keeps your itouch/iPhone on all night so youll need to plug it in over night!
