Good with room for improvement.
This is a good app with a great idea behind it. There are definitely some bugs keeping it from 5 stars though. For instance, it wont reevaluate free time for today unless you actually open the today view and let it recount. Doesnt really crash, but needs some work before it gets 5 stars from me. Great concept. Decent and functional execution. Could be better.
