ChessImprover is a complete chess training app: play with a coach by your side, solve puzzles, build an opening repertoire, and master the endgames — powered by a strong engine that runs entirely on your device. PLAY WITH A COACH — NEW Relaxed, untimed games with a coach commenting on every move you make — in plain words, not chess notation. The coach speaks its advice out loud (you can turn the voice off), names the openings you play, and when something goes wrong it offers to take the move back and try again, with a hint if you're stuck. PLAY AT YOUR LEVEL Challenge the built-in engine anywhere from 500 to 2900 Elo. Climb the ladder of 25 rated bots, or play relaxed unrated games with no clock. Stuck? Ask for a hint. REVIEW EVERY GAME Every move explained in plain English — what worked, what didn't, and what your opponent's move set up. Inaccuracies, mistakes and blunders are flagged move by move, the summary shows the turning point and what to train next, and you can watch the whole game back as a narrated replay. See exactly where you left your opening prep, and explore alternatives on the analysis board. SOLVE 23,000 PUZZLES Tactics from real games, matched to your level. Rated mode tracks your own puzzle rating, timed mode races the clock in 3, 5, and 10-minute rushes, and custom mode lets you pick a difficulty and solve at your own pace. BUILD A REAL OPENING REPERTOIRE Answer a few questions and the wizard assembles an opening repertoire for White or Black — real lines with clear explanations, from simple beginner systems to a full club repertoire. Then drill your lines with spaced repetition so they stick. MASTER THE ENDGAMES THAT DECIDE GAMES Curated drills for the endgames every player must know: queen and rook checkmates, king-and-pawn opposition, and the Lucena and Philidor rook endings. Win the winning ones, hold the draws. LEARN FROM ZERO New to chess? A built-in guide teaches the rules from the very first move. Private by design: no account, no sign-up. Everything — the engine, the puzzles, even the coach's voice — runs offline on your device. Questions or feedback? chessimproverapp@gmail.com
