Stopped working correctly since iOS 10

Still my go to wake up app, but since iOS 10 it stopped working properly. If you leave it open it should stay open and go off in the am. Now it crashes overnight and sends alerts on your lock screen but you have to open the app again to shake it off. If you accidentally leave your phone on vibrate youre screwed, unless youre a light sleeper – and if you are, you dont need this app.
