Auto-Scoring Tutorial

DartsOn auto-scoring can score your darts using just your device’s camera. Point the camera at the board, play as usual, and the app reads each dart and enters the score for you.

Key Features

• Built-in device camera is all you need. No extra hardware required.
• Works with a wide variety of camera angles and positions out of the box.
• Runs a custom DartsOn model fully on-device — no network needed after the initial model download.
• Works with most steel-tip dartboards and darts.
• Supports both portrait and landscape orientation.

Set up your device

• Keep the device steady. Place it on a tripod, shelf, or holder so it doesn’t move or shake during the game.
• Fit the whole board in view. Center the dartboard and let it fill most of the frame, like in the photo above.
• Get close rather than zoom in. Move the device closer instead of relying on zoom too much where possible as excessive zoom can degrade image quality and thus detection is worse.
• Use a slight angle. Moderate angle works best. Avoid straight-on and extremely steep angles.
• Light the board evenly. Wide range of lighting conditions are supported. A dedicated dartboard light from multiple points is ideal, but not required. The app will let you know if the image is too bright, too dark, or has strong glare.
• Plug in a charger. On-device processing uses more battery than normal play.

The scoring screen

The live camera view sits at the top with your score below it. A few controls are worth knowing:

• Camera icon (top right) — enable or disable auto-scoring.
• Feedback icon — report a scoring issue.
• Pinch to zoom - adjust the zoom of camera to frame the board.
• Previous / Next turn - step back or advance the turn manually when you need to.

During the game

• Throw as usual. Each detected dart appears on the scoreboard as it lands.
• Remove your darts to end the turn. After your third dart, remove the darts from the board - the turn is confirmed and play advances to the next turn automatically.
• Correct any dart manually. When necessary, tap a dart slot to edit it. Auto-scoring and manual entry work together seamlessly.

Occluded darts

Sometimes a dart lands directly behind another, from the camera’s point of view, so the tip of it is partially or fully hidden and isn’t automatically detected. When you see a dart being undetected after all three throws:

• Remove the darts one at a time, starting with the ones closest to the camera.
• As each occluding (blocking) dart comes out, the camera can see the dart behind it and score it.

With this technique, DartsOn auto-scoring should score more than 95% of darts automatically.

Turn control

Most of the time the app advances the turn automatically once it sees that the dartboard is cleared. You only need to use the previous/next turn buttons in a few cases:

• The last dart slot was filled incorrectly. Use the previous turn button to go back, tap on the slot with the incorrect value and manually edit the score. Then press next turn to proceed.
• All darts missed the board. If all the dart landed outside the camera view, you’ll need to press the next turn button to proceed. If at least one dart landed, then clearing the dartboard will fill the empty dart slots with MISS (0) and automatically proceed to next turn.

Troubleshooting and Feedback

DartsOn Auto-scoring handles a wide range of dartboards, darts, and lighting, but it’s still in Beta, so some setups may not work perfectly yet.

If that happens, please use the Report Scoring Issue button (located at the top right corner of a camera view) to send feedback. We’re actively improving the model, and seeing real setups (your dartboard and how the darts land on it) makes a big difference in finding gaps. Any other feedback is welcome too.

Auto-Scoring Beta

During the Beta, everyone gets a generous number of free games with auto-scoring. Later, only a small number of games will be free, and Premium will be required beyond that.

Also during this period, Settings → Data Controls → Improve camera-scoring model is enabled by default (and can be disabled). This helps us collect feedback and make auto-scoring even better.
