Begins to crash and won't reopen – Good Habits Review

Immediately after paying for the full version the program began crashing/closing. You can't reopen the app either by closing and reopening it or restarting your phone. The last time I deleted and reinstalled the app and that worked though I lost my progress. When this happened again today I realized this wasn't a random problem.
