What happened to this app?

The recent updates have made this app so much worse to use. When you go too deep in a line, it no longer shows stockfish suggestions. Even if you play the move on the board, there is no evaluation.

It will often say “clear best move” when the move is even with, or WORSE than the best move. Often, moves are marked mistakes that are literally the best move in the position. And even the stockfish suggestions are wrong. It will show one move that wins and three or four options that lose, but if you open the Lichess analysis, there are several moves that keep the advantage.

I love this app but I hope they fix it soon.

Low friction for keeping a repertoire

I have tried to keep studies in Lichess for my repertoire, but have struggled to keep up with it. Chessbook makes it easy. After any game I can effortlessly update and improve my repertoire. Love it!

Best repetition practice

I usually would hate on apps but this game teaches you what to look out for in opening game practice. Try it out

Please add streak widget

Chess.com allows you to add a widget so that you can easily see what day your streak is at and it serves as a reminder as well to actually open the app and extend your streak so you keep learning. I think your app should add that as well, it has helped me keep a streak on chess.com and Duolingo for over 200 days but I keep losing my streak with this app I think because there is no widget on my home screen serving as an easy reminder. Great app otherwise though
