Good but keeps crashing on me

Im on iphone 6, updated os. Good levels and app seemed ok at first, but crashes more frequently as I moved on. Just barely managed to get it to run long enough finish level 8 after many tries, now cant play long enough do level 9. Crash does not seem to have much of a pattern as to when and what I was doing at the time.
