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.

Chessis is a solid app for chess players of all levels. The puzzles are helpful, the analysis tools are great, and the interface is clean. I really like how it breaks down my mistakes and shows better moves. However, some advanced features are locked behind a paywall, and the free version can feel limited after a while. Still, a great app for improving your game!

So I stumbled upon the app at random .... At first , the eye catcher was ofcourse the free analyzer that resemble d the one on chesscom. After using it for a while to analyze games from lichess and chesscom , it felt like a much harsher version of the chesscom one but can't complain as it is free !! , soon couldn't just resist to get the paid version which is even better . Overall a solid investment 👌 💯. Even the free version is awesome !! Well done Development 👏
