Sleeping is the main relaxing time for all of the people. But mostly it depends on stage of sleeping, when alarm rings. And if stage is right, you will wake up refreshed. So I decided to create an Windows Phone App for that.

So first of all I designed iteraction. Fot this task i prefer to use UML Action Diagram. It is easy to use and to understand.

After that I have splitted all functions into screens.

So when I have screens I can create interface.
