Crashes, erases progress

After a few minutes of writing a new prompt, the app crashes on my 4S on iOS7 and doesnt save any of the work.
This happens /every/ time and it even happens with already saved prompts, though it will thankfully save the work in that situation.
Please fix this, guys. I loved this app before this recent "update" broke it for me.
