ChessImprover

Play chess at your level, drill tactics, build an opening repertoire, and master key endgames — with instant game review after every game. All on your device.

ChessImprover is a complete chess training app: play, puzzles, openings, and endgames in one place — powered by a strong engine that runs entirely on your device.

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 Get an instant post-game review: inaccuracies, mistakes and blunders flagged move by move, with an interactive analysis board to explore what you should have played — and see exactly where you left your opening prep.

SOLVE 23,000 PUZZLES Tactics from real games, matched to your level. Pick your difficulty range and solve at your own pace, or race the clock in 3, 5, and 10-minute rush modes.

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. Your games and progress stay on your device.
