TacticSnap: Chess Scanner

Turn any chess screenshot into a position you can explore. Scan the board, check uncertain squares, and analyze the best lines with Stockfish—right on your iPhone.

See a chess position worth exploring? TacticSnap turns a screenshot or photo into an interactive board in seconds.

Share an image with TacticSnap from Photos or another app, choose one from your library, or take a photo. The app finds the board, recognizes the pieces, and opens the position ready for analysis.
