How a night runs

From the door to the podium.

One app carries the whole evening, and every result lands in your club's history.

1

Doors open

Who’s here, who’s paid.

Add your regulars from the player database, or sign up walk-ins on the spot. One click marks a player paid, and the draw waits until everyone has: nobody is left out.

Because retyping names is not a sport.

Player Registration: players counted, paid and unpaid

The draw

Pick a format. Draw.

A card for every format, each showing what it means for tonight’s players. Seeding from your own results keeps the best players apart; otherwise it’s a fair random draw.

The bracket doesn’t play favourites.

All night long

The bracket, centre stage.

From the draw to the final, every round fits on one screen, from 8 players to 48. Big enough to read from the bar.

No more crowding round the laptop.

  • Follow a player. Their path through the bracket lights up, everything else dims.
  • Click a match. See where the winner goes, and where the loser drops.
  • Finals in the middle or on the right. Switch at any time.
  • Every format drawn its own way. Cup and Plate back to back, groups beside their cups, Swiss into its top four.

On the boards

One panel runs the room.

A tile for every board in play: click the winner to finish a match, a free lane to start the next. Referees are suggested, and nobody gets double-booked.

Less admin. More darts.

Match Controls: a tile for each live match, the free lanes and the next match

At the oche

Scan it or send it.

Phones and tablets at the boards keep the score with the Chalker. Matches go out and results come back by QR code or over your own network, with every 180, high out and short leg.

No shouting results across the room.

The final

Give the winner their moment.

A podium with the night’s highlights (most 180s, shortest leg, highest out), made to be photographed for the club chat.

The night ends. The record doesn’t.

The morning after

Every night adds up.

Season standings, player profiles with form charts, finishes and averages, filtered to the nights that count. Members follow it on their phones.

Settle the bar arguments.

Built to last

Built for the room, not the cloud.

Works offline

No Wi-Fi at the venue? It doesn’t need any. Everything runs in your browser, and keeps running if the network drops.

Yours, not theirs

No signup, no subscription, no tracking. Your results stay on your computer, or on your own server.

Never loses a result

Every result is recorded in the tournament’s history, so a mistake is undone, not patched by hand.
