ChessWOW Stockfish 19 Analysis

ChessWOW analyses chess positions and games with Stockfish 19 on your iPhone or iPad.

Import a position from a Chess.com or Lichess screenshot, or take a photo of a chess diagram on a screen. Recognition runs on your device. Adjust the board corners, check the pieces and select the side to move. You can edit the recognised position before analysing it.

Import games as PGN or positions as FEN, or set up a position yourself. Explore evaluations and variations, compare alternative moves and examine critical moments in a game report. Keep your games in the library or play against Stockfish.

Chess calculations run locally and can work offline. Online imports, loading purchase offers, purchases and restoring purchases require an internet connection.

Using ChessWOW requires ChessWOW Pro: an auto-renewing subscription (weekly, monthly or yearly, with a free trial depending on the offer) or a lifetime one-time purchase. Prices and periods are shown before purchase. Subscriptions can be cancelled anytime in your Apple subscriptions.
