Major Problems – Chess Openings Pro Review

This app has so many errors that it's not funny. In quiz mode it tells you that you are correct when the data shows that you are wrong and it says that you wrong when the data shows that you are correct. Others have complained about this flaw but it looks like no attempt has been made to correct this major flaw! Too bad, otherwise it could be a good app.
