Keeps crashing

I had to keep restarting when loading clips then finally got them to load without crashing my adding one minute or less at a time. Kept having to re-record the audio because if theres a mistake, you have to do it over but you cant save good recordings. After an hour of getting all the footage and audio finalized I tried to save it to my camera roll and the app crashed again! Nothing was saved and an hour of my time was wasted.
