Great App When it Works – Chess Viewer Review

I love many features about this app, particularly the selection of books, the split screen, and the evaluation engine, among others. Unfortunately, this app crashes before I can access my purchased books most of the time, so I cannot read them, which is quite frustrating. I have used this app since its inception, but never had a serious problem until very recently. Please fix the crashes and I will award this app the five star rating it deserves.
