About

Play chess, analyze your games and practice on iPhone and iPad with Stockfish 19 and 11 engines running on your device. Choose among 19 difficulty levels in Stockfish and Karsli, explore openings, or arrange engine matches and tournaments.

Enable the optional Chess Coach for feedback on your moves. Use Game Review to study mistakes and suggested continuations. Evaluations and game ratings are engine estimates, not official player ratings. Turn a board photo into a position for analysis; check and correct the recognized pieces. Physical-board recognition is experimental.

Save, import and export PGN games, and copy FEN positions. Play, analysis, coaching and photo processing work offline without uploading games or photos. Public-game imports and optional endgame database downloads require internet access.

Independently developed by Tughan Y. Karsli. Not an official app of the Stockfish project.
