What I learned with crashing apps is it is always better when you have all other apps closed. I mean closing it from memory altogether by double clicking the home button and then closing the app from there.
another thing is also it helps is there is a minimum of 1GB space free in the iPad.
If it still crashes, then usually (for me) it has been within the issue, such as links etc.
When does your app crash? for me it used to crash whenever I clicked certain links. What I discovered later was that the links that used to crash my apps had wrong
selections. When infact my actual link was addressed to a jumplink, I had accidentally chosen 'link'.
Let me know how or when it crashes and I will try to help as much as I can.
