I’m sorry the app is crashing on you so much. iOS is a challenging platform to write for – if an app uses the tiniest amount more memory than the system can support, the app is instantly terminated by the OS. I have made significant improvements to Auto Enhance for the next release (3.1). It uses much less memory and is much faster as well. That should help a lot with the first crash.
As far as the other one, it’s hard to tell right now. If you are interested in beta testing the 3.1 release, please email firstname.lastname@example.org and I can put you on the list. Maybe we can figure out the second one too.
