I had the open -> immediate crash issue, but only on my iPhone 6, not on my iPad. Anyway, I was running an iOS 8.4 version or whatever.
Updated to iOS 9.3 and it was immediately fixed. App opened effortlessly.
All that said, I agree with others that the App is quickly exhausted and interest is quickly lost - and for 300 MB, Im going to delete it.
