Put the phone on the oche and play. BullSync is a darts scoreboard for 301 and 501 that runs entirely on one device — tap the board to score each dart, and let the announcer call it out while you throw.

No account. No ads. No internet connection. Ever.

TAP THE BOARD, NOT A KEYPAD
BullSync draws a real dartboard and you tap where your dart landed. Singles, trebles, doubles and both bulls are picked up from the spot you touch, and the segment flashes so you know it registered. Miss the board, tap outside it — that scores zero, same as real life.

CHECKOUT HINTS WHEN THEY MATTER
Sitting on 96? BullSync shows you the way out. Finish paths appear for every checkout from 2 to 170, with up to three alternatives so you can throw the one you actually trust. Above a finish, it suggests a setup shot instead. Hints re-work themselves after every single dart, and stay hidden until you're in.

RULES THAT MATCH YOUR HOUSE
- 301 and 501
- Straight, double or master in
- Straight, double or master out
- Bust detection that respects the out rule you picked
- Best-of legs format

THE ANNOUNCER
Your device's own voice calls each dart, your turn total, busts, the leg and the winner — big scores get called louder. Pick any voice installed on your phone, set the volume, or switch it off from the scoring screen with one tap. Nothing is downloaded; it uses the text-to-speech engine already on your device.

BUILT FOR A REAL NIGHT AT THE BOARD
- Add as many players as you have, each with their own colour
- Drag to set the throw order
- Somebody turns up late? Add or drop players mid-match, between turns
- Fat-fingered a treble? Undo any dart, one at a time, right back through previous turns
- Phone rang? The match is saved as you go — pick it up from where you left off
- Rematch the same players and rules with one tap

TRACK WHO'S ACTUALLY WINNING
Every match is kept. Open one up and see the leg-by-leg breakdown with a chart of how the scores fell away. Each player gets a card showing win rate, average score per turn, best leg and lifetime 180s.

MAKE IT YOURS
Dark, light or follow your system theme. Vibration on or off, separate from the sound. Set your usual game mode and in/out rules as the default so a new match is two taps away.

YOUR DATA STAYS ON YOUR PHONE
BullSync has no servers, and no way to talk to one. Players, matches and stats live in a database on your device and go nowhere. Nothing is collected, nothing is shared, and there's nothing to sign up for.

Hit the mark. Sync the game.
