Ratings and reviews

Best free chess game ever. Gives you an analysis after each game. You can step through each move of the finished game and it shows where you should have moved and indicates if each move is a book move, or the best, good, inaccurate, mistake, or a blunder. it also has example openings you can study. Also, no ads.

This is an amazing app, I use it without getting the full version, and it has every feature needed. You can play against a friend on the same device two different ways and you can play a bot. I love the extra touch where you can make two versions of Stockfish play each other and set up the board randomly. It also is excellent at analyzing moves and helping you evolve the game. In all, great app.

The board scanning from images/screenshots definitely needs to improve. I use it a lot. Compared to chessify, it performs relatively poorly. _____ When adding variations to be analyzed, there's no need for the pop-up notification stating how many variations are now being analyzed. The number being analyzed is obvious, & the pop-up just covers the variation analysis lines so I waste time waiting for it to disappear so I can actually see the variations. Otherwise the program works well.
