Fair playMost chess sites do not allow engine help in games you are playing.

On iPad

More room to study the position. On iPad, the board and analysis sit side by side.

How It Works

Bring in a screenshot and the app reads the board, then analyzes it automatically. If anything is unclear, it asks you to check the position first.

  1. 1.

    Take a Screenshot

    Capture a flat, digital board with the whole board visible, such as a position from a game you are reviewing or a puzzle.

  2. 2.

    Bring It In

    Tap Use latest screenshot, choose an image from Photos, share or paste it, or run your screenshot shortcut.

  3. 3.

    Check the Position

    The app finds the board, identifies each piece, and works out which side is at the bottom and whose move it is. Squares it is unsure about are marked, so you can confirm or fix them before anything runs.

  4. 4.

    See the Best Move

    Stockfish 19 thinks for the time you choose, then draws the move as an arrow over the board and shows it in notation, with the evaluation and the line it expects.

What You Get

Recognition and analysis both run on your iPhone or iPad. There is no account to create.

Recognition on your device
The app finds the board with its own image code and reads the pieces with a Core ML model built into the app. Squares it is unsure about are marked for you to check. It handles common layouts, such as a board beside an evaluation bar, highlighted last moves and drawn arrows. Textured board themes and unusual piece sets may not be recognized yet.
Stockfish 19
The Stockfish 19 chess engine and its standard neural network are built into the app. Analysis works without an internet connection.
Think time you choose
Let the engine think for 1, 3, 5, 10 or 30 seconds. Running the same board again with a longer time, the other side to move or the board flipped does not use another analysis.
A consistent board
Classic green is the default. In Settings, choose Match screenshot to use the colors and pieces from your image, or choose Standard board. Your preference stays in place. You can still correct any piece the app read incorrectly.
One-step Shortcut
Take a screenshot, save it to Recents, and pass that image to Find Best Move. Run your shortcut with Siri, Control Center, the Action button or Back Tap. Follow the setup steps.
Screenshots stay on your device
No account, no analytics and no ads. Screenshots and positions are analyzed on the device and never uploaded. Privacy policy
VoiceOver and larger text
Moves are read in words, text follows your Dynamic Type size, and the arrow’s blue stays distinct for red-green color blindness.
Home and Lock Screen widgets
Save a screenshot, then tap the widget to open Chess Best Move and analyze it. Widgets use your latest saved screenshot; they do not take a new one. Add a widget.
