seems like this app hasnt really been updated since ipad 1. same issues exist and same mistakes. the solver has not worked on many problems since Ipad 1, and now in the ipad air 2 era the same issue exist. You are given a puzzle, you cant find the answer so you decide to ask the solver for the solution, only to have the solver tell it cant be solved. so you waste time solving a puzzle with out a solution. Not just a few puzzles but many puzzles. Also many are wrong. also many puzzles will say mate in something but if you enter it into a chess engine the mate is in a different number. They need to stop selling this app which has had the same problems since ipad 1 until its corrected and they should check their puzzles with a chess engine that is legit.
