Answer 2

I had the same problem and found that my IOS device didn't have enough storage available to operate the app and have deleting some unused apps and freeing up space on the IOS device the apps stopped crashing.

Also make sure you have enough memory available to operate the app because that can cause problems too.

If that isn't it then you may need to completely backup your IOS device and then restore it it factory settings for the apps to work without crashing.
