I hate to be the "the old version before the update was better" guy, but the old version before the update was totally better. Now it has a circle thing which you have to rotate and its just awful. It used to be that you could either enter your wake up time and it would give you your list of times, or you could choose "sleep now" and it would give you your wake-up times if you went to sleep within 15 minutes. Now, if you manage to work the awful circle thing, it just gives you one wake-up time. This app served me well for a long time. Sorry guys, you did the classic "fix it when it wasnt broken" scenario. Oh well, more free space on my phone.
