Chess Next Move Calculator

Point your camera at any chessboard and get the best move in seconds. Stockfish runs right on your iPhone — no internet, no data, no waiting.

Point your camera at a chessboard and find the best move in seconds.

Chess Next Move Calculator runs Stockfish — the strongest chess engine in the world — directly on your iPhone. Set up any position, get the best continuation, and understand what you should have played.

SCAN A REAL BOARD Playing over the board, reading a chess book, or stuck on a puzzle in a magazine? Photograph the position and the app reads the pieces for you. Fix anything it misread with a tap, and you have a live position ready to analyze — no manual setup.

FIND THE BEST MOVE Stockfish evaluates the position and draws the strongest move straight on the board. Adjust how long the engine thinks: a quick read when you just need a check, a deeper search when the position is sharp. Analyze as White or as Black.

SET UP ANY POSITION Tap to place pieces on an empty board, or paste a FEN string to load a position instantly. Flip the board, take back a move, or clear and start again. Useful for studying an opening line, working through a tactics puzzle, or replaying the game you just lost.

PLAY AGAINST THE ENGINE A full game against Stockfish, with difficulty set by Elo rating — dial it down to a gentle opponent while you are learning, or up to a level that will punish a careless move. Castling, en passant and promotion are all handled. Track your score, your move count and your personal best.

WORKS WITHOUT A CONNECTION The engine is built into the app, so analysis and games run with no internet and no data usage — on a plane, on the subway, anywhere. (Board scanning is the one exception: photo recognition runs on our servers.)

49 LANGUAGES Including Hindi, Spanish, Portuguese, Arabic, Russian, German, French, Japanese, Korean, Turkish, Vietnamese and Indonesian, with full right-to-left support.

FREE TO USE Engine moves and take-backs draw on a coin balance that refills on its own, so you are never locked out. Premium removes coins altogether and supports continued development.

Whether you are reviewing your own games, solving puzzles, preparing an opening or simply want to know the move you missed — Chess Next Move Calculator gives you an engine-strength answer in seconds.
