Point your camera at the dartboard and let the app keep score — spoken results, automatic detection, full 501 / 301 and free-throw games.
Works best in good, even lighting with the whole board in frame.
Drag the four dots to the outer edge of segments 20 (top), 6 (right), 3 (bottom) and 11 (left). The green outline should sit on the board's wires.
Tap the board to correct the score.
