Decent problems, needs work

There are a lot of decent problems, and the prices for packs is not bad at all. The real problem (other than the crashes) is that on a phone you usually can't see all of the text, if text comes with the problem. Oftentimes the text will explain a situation, there will be marked stones on the board, and you won't know what it is they want you to do if the text is too long.

I really enjoy doing problems, but some fixes need to be made to this app in order for that to be possible.

Also, as another suggestion, It would be nice if the problem sets were by rank. I wouldn't mind paying a little extra for problems around where I am instead of getting a bunch of problems that I can't use.

App keeps crashing when I restart a level and most of the levels don’t even explain to you what you’re supposed to do. I like knowing what rank I am but at the same time my rank goes up too fast and I don’t even understand most of what I’m doing

Crash Problems

I love this app, I think it's really great. The only problem is it keeps crashing. Please fix that so I can continue to play.
