Got this app last night at 10:30. Played with it and got it set for 6 am. Used it as a bedside clock at 10:42 with 92% battery remaining. After I woke up at 6:30 am wondering if I just hit the snooze I realized it completely drained my battery. I just deleted the app and wanted to let you all know to get another alarm clock app.
