Train your mistakes — free. After a game review, tap "Train your mistakes" and every mistake or blunder becomes a puzzle in your personal drill queue. Replay the position, find the better move, and retry until it sticks. No account, no membership. Also new in this version: • Coach commentary — plain-English reasons for the move on the board • Opponent threat arrow — see what you are up against in one tap • Board themes — four board colors to choose from in Settings • Real Chess.com and Lichess marks on the import screen • Faster, smoother boards (new app runtime) • Crash reporting, so problems get fixed faster
