About this app

Learning chess? Start here. ChessCoach is built for players who want to actually get better — not just play. Every move you make is graded instantly by Stockfish, a real chess engine, so you know right away whether it was good, and a free hint explains why in plain English. No jargon, no guessing. LEARN, DON'T JUST PLAY New to chess or stuck at the same level? Structured lessons walk you through tactics patterns, endgame basics, and the ideas behind common openings — the "why," not just the "what." IMMEDIATE FEEDBACK ON EVERY MOVE Play a move and instantly see how it graded: brilliant, good, inaccuracy, mistake, or blunder. No more finishing a game and wondering where it went wrong — you find out the moment it happens. FREE HINTS, EVERY TURN Stuck on what to play? Get the engine's best move and a one-line explanation of why — completely free, no daily limit, no paywall. It's like having a coach look over your shoulder. PLAY OFFLINE, ANYTIME The engine, hints, move grading, puzzles, and lessons all run right on your device — no internet connection needed for any of that. Practice on a plane, on the subway, anywhere. (Board scanning and the Pro written coach do need a connection.) MASTER YOUR OPENINGS Learn opening names live as you play, then build a real repertoire with the Opening Trainer — understand the plans behind the moves you've been copying. SHARPEN YOUR TACTICS WITH PUZZLES Solve curated puzzles pulled from real games, drill checkmates, and race the clock in Puzzle Rush — free, with no daily cap. SCAN ANY BOARD, ANYWHERE Photograph a physical chessboard mid-game and pick up play instantly — no manual setup, no re-entering every piece. REVIEW EVERY GAME After each game, get a full move-by-move breakdown: your blunders, your brilliancies, and exactly where the game turned. WHY IT'S DIFFERENT Most "AI chess coach" apps are chatbots that guess at good moves. ChessCoach is built on Stockfish, a real chess engine that calculates millions of positions per second — every hint and grade comes straight from what the engine actually found, running on your device. No hallucinated analysis.
