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.

An Excellent App for Analyzing Chess Games! This is hands down one of the best apps for analyzing chess games. The features are top-notch and incredibly helpful for improving gameplay. However, I’d love to see one additional feature: the ability to analyze multiple games at once—say, 1000 games or more—and generate a comprehensive report based on the analysis, similar to what Aimchess offers. Adding this functionality would take the app to the next level...:)

This is an amazing app! It helps me analyze and save all my games, allowing me to review them anytime for improvement. edited: One observation: I have observed that app can't recognise an alternative move. If the app suggested a fork in two move, while doing the same fork in two moves but using different squares, it shows inaccuracy while there is no threat post that move in either way.
