What is my sleep cycle?

Great sleep calculator based on basic information. But you cant view how (or IF) the app is incorporating your own sleep data into future calculations. Whats the point of having it on the mattress? I bet I can leave it on the table and it would do the same thing.

Regardless it is a pleasant and helpful alarm system. I do feel more refreshed.
