Dart Tracker is a darts scorer for iPhone. It plays X01 (101 up to 1001, with double in, double out and first-to-N legs) and Count Up, for any number of local players in a throwing order you can reorder.
You score a turn in one of two ways: tap where each dart landed on an SVG dartboard, or pick each dart on a keypad. The X01 rules live in a pure module, separate from the screens, and handle bust detection, undo across turns and checkout suggestions for the remaining score. A flying-dart animation, sound effects and haptic ticks while aiming make it feel closer to the real board.
Parts: Dartboard (tap · SVG), Keypad (pick each dart), Game session (turn flow · undo), X01 rules (busts · checkouts), SQLite (Drizzle · on device), History + stats (per match · all-time).

- Game session to X01 rules (dart)

Everything is stored on the device with Drizzle on expo-sqlite: game history, a summary for each match and all-time stats per player. There’s no account and no network connection.
