Crashing Too Often

When I first got this app I loved it. I like seeing how my night of sleep went, how much rest I got, and the sounds to help me fall asleep.

But as of lately Im ready to go back to the built in alarm clock. Since I updated to iOS 10 the app crashes or my phone locks and my alarm doesnt sound. Luckily Ive woken up in enough time not to be late but Ive overslept every time this happens.
