Fun but very little offline support and no saving word lists

I just spent an hour collecting definitions from my textbook and typing them into this app. I compiled 45 definitions in total, and the app will not let me save the list no matter what I do. It keeps giving me an error.

The word lists are fun, but they only work when you have internet. Not worth more than $2 for this app in its current state.
