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.

It's a good app, but when you set the playing level at say 2300 elo, and then you sign out of this app, it always defaults back to the start (200 elo). I want it to stay fixed at the level I left it at; like the playMagnus, and Lichess apps. You can fix the playing level on those two excellent chess apps and when you return, it's still at that level no matter how much time passes. You can't do that with this app. Once you sign out, when you come back, you have to reset your level again.

Position of main board during analysis seems to go wrong. It can be right at the top with no opening info or moves visible or completely centered with not enough room for more than one line of engine moves on my device. Sometimes its just right but not sure how to change it or get it to recalculate. Otherwise excellent :-)

Hello Paul, Thank you so much for the 5-stars ratings. the app tries to adjust the board position according to the available screen size. please try to enable "Full Screen" mode in the app settings that should fix the issue, as it allows some extra space! Thank you for your patience with my late response 🙏🏻 Have a great day:)
