How it works
Set up once. Then just throw.
Stand your phone by the board
Beside the board or in front and to one side: on a surround clamp, tripod, stand or shelf. The Fill, Centre and Angle meters show you when the position is right.
Calibrate and tap Start Game
Start a game and tap the camera button. DartsKEY finds the board's ring and locks on. Save a lighting preset for a bright or dim room.
Throw, check, pull your darts
Each dart is scored as it lands. You see the visit before it counts, fix any dart with one tap, and the turn passes when you pull your darts.
Real boards. Real players.
Built for the board on your wall
These are DartsKEY team players' own set-ups. No studio and no special kit: their own boards, phones, tablets and TVs.

FAQ
Good questions
What is DartsKEY?
DartsKEY is an automatic dart scoring app for iPhone and Android. Point your phone's camera at your dartboard, throw, and the app reads where every dart landed and keeps the score for you. Play X01, Cricket, practice drills and party games on your own, against DartBot, with friends in the room or online.
Do I need any extra cameras or hardware?
No. DartsKEY uses the camera on the phone you already own. All you need is your dartboard, some steady light and a way to keep the phone still: a clamp on the surround, a tripod, a phone stand or a shelf. See the set-up guide.
Where should I put my phone?
On something steady facing the board, so the whole board, number ring included, fits in the camera picture. Keep the phone upright, so the line between the 20 and the 3 looks roughly vertical, and put it to one side rather than straight on, as far as the Angle meter asks. The Fill, Centre and Angle meters tell you when it's right: adjust until they turn green. Set-up guide.
What if a dart is scored wrongly?
You can fix it before it counts. Every visit ends with a check showing your darts: tap Edit, tap the wrong dart, choose the right segment (or MISS) and tap Confirm. You can also tap a dart's box during your turn. In online X01, Edit last lets you correct your previous visit until the next player's first dart lands.
Which games can I play?
16 games, all scored by the camera. X01: 301, 501, 701 or 901. Cricket: Standard, No Score, Tactics, Random and Cut Throat. Practice: Around the Clock, JDC Challenge, 41-60 and Catch 40. Party: Hammer Cricket, Half It, Killer, Shanghai, Bermuda and Gotcha. Rules for each are in the side menu under Darts Rules. See the games.
How do I invite friends to a game?
Choose a game, tap Play Friends and Continue, pick friends from your list and tap Send Invitation. The game starts by itself once everyone has accepted. An invitation can be accepted for 120 seconds; if you're in a match it waits until you leave it.
Unlock your game.
Put your phone by the board and let DartsKEY keep score. You just throw.
