Randomly while Im asleep, random times

I love the app. The only problem is that maybe 3 times out of ten, I wake up In the morning after having set Pillow to wake me, to my iPhones homes screen, and Pillow has crashed sometime in the night and all my data for that night is lost. Who else has this issue. Lets get the hard working developers to fix this bug for us! :)
