Turn your handwritten chess score sheets into digital games in seconds. Take a photo of your score sheet, and Chess Scanner reads the moves, generates the game and shows it next to your handwriting, so you can check every move at a glance. HOW IT WORKS • Scan the score sheet with the camera or pick a photo from your library • The move grid, the notation and the last move are detected automatically • Generate the game with Basic (fast and reliable) or Pro (for hard to read score sheets) • Check the result: each move is shown next to the handwritten field, and the color shows how confident the recognition is • Misread moves are corrected automatically where possible, and uncertain moves are marked for a quick look • Fix a move in seconds with suggestions sorted by probability, filtered by piece if needed ORGANIZE AND SHARE • All games in one place, with search and filters by tournament, round, result and favorites • Group games into tournaments and add player names, ratings, date and round • Export single games or whole tournaments as PGN, or import your existing PGN files • Open games in Lichess or Chess.com • Analyze games and see the accuracy of both players, their mistakes and the evaluation over the game • Find your games with Spotlight search FOR TOURNAMENT DIRECTORS Add the score sheets of both players. Both are used to generate the game, which makes the result even more reliable. Long games can span several sheets. MADE FOR EVERY SCREEN Works on iPhone and iPad, with the games list and the game side by side on iPad, and with dedicated layouts for iPhone Duo, folded and unfolded. SUPPORTED NOTATIONS • English: N/B/R/Q/K • German: S/L/T/D/K • Dutch: P/L/T/D/K • Spanish / Italian: C/A/T/D/R • French: C/F/T/D/R • Portuguese: C/B/T/D/R • Czech / Slovak: J/S/V/D/K • Turkish: A/F/K/V/Ş Other notations can be set up as well; they are read based on a similar supported notation, so recognition may be less accurate. To generate a game, the score sheet images are sent to our servers. Generation usually takes a few seconds, depending on the legibility, the length of the game and your connection. PREMIUM • Pro generation for hard to read score sheets • Score sheets of the second player • Game analysis • PGN export • Open games in Lichess and Chess.com • Cloud synchronisation of your games • Unlimited chessboard scans The core features stay free.

Verdict

The call

The clearest difference is ads: Chess Scanner at none against Unlock's shown. Unlock's advantage is ratings volume (3.5K vs 22) and update cadence (every 6 days vs every 3 weeks). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Chess Scanner sells 6 in-app purchases, starting at $2.99 per 7 days and Unlock sells 10 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 3.9 for Chess Scanner against 4.0 for Unlock. That said, the two scores are not equally well evidenced: Unlock has 3.5K ratings behind it against 22, so its average is the more settled of the two. Written reviews are what separate them: 60% of Chess Scanner's written reviews are positive against 58% of Unlock's.

UpkeepUpdate frequency

Chess Scanner ships an update every 3 weeks, Unlock every 6 days. The most recent releases landed on October 30, 2026 and November 1, 2026 respectively.
