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 app is amazing! I have a few suggestions: Could you please allow premoves and a bar that allows you to toggle "draw arrow" or "change arrow color"? I think it will make things neater. Could you allow the app to analyze while I set up a position? It would allow illegal moves, like when I play against a chatbot AI. Finally could you fix the problem in which when a bot has under three seconds to move in a timed game, it starts playing insanely good. Thank you very much 😊

Thank you so much for the great review, Hamy! 😊 Glad you’re enjoying the app. Your suggestions are thoughtful and noted, while many things are in the queue, some of these ideas might be considered in future updates. Thanks again for your support! ♟️

If I could rate it a 3.5, I would. The app is great for playing bots, also featuring the bot Maia. But for the analysis, there are definitely some improvements that can be made, like in the opening, and when you drop from 0.7 to 0.4 and it considers it a mistake (it's a book move) I haven't bought the premium thingy, but how would it even explain why the move is bad, it doesn't make sense. I finish games with 8 mistakes but when I check and analyze, they just turn out to be light inaccuracies
