Mostly good
This app works well most of the time, just a few things I would change:
1) App often stops working (without warning) if minimized.
2) Consider offering a variety of sounds for the alarms.
3) Asks me to review it positively EVERY TIME I open the app. Though it worked, I am reviewing, its not one of my more positive reviews.
That all being said, its free and works fine most of the time so I continue to use it.
