App WAS great until last update

The last update messed up a great app! It wont stay on when the screen turns off- so its impossible to use to relax or help sleep or anything it was supposed to do because it keeps turning off!
PLEASE FIX / UNDO LATEST UPDATE- IT DIDNT FIX ANYTHING- IT RUINED THE APP FOR USERS!
