Badminton Scoreboard App: Rally Scoring From a Phone

In this guide
A badminton scoreboard app lets a player, coach or umpire record every rally on a phone while the court TV shows the score to everyone. With Multi Score Screen there is no app to install: scan the QR code on the court TV, enter the PIN shown beside it and the phone becomes the controller for that match. You tap the side that won each rally; the scoreboard adds the point, moves the serve indicator and applies badminton's game rules for you.
Why rally scoring suits a phone
In badminton every rally scores a point. That is simple to follow, but it means the score changes every few seconds, and a match produces dozens of points per game. Writing that on paper or flipping numbers on a scorer slows the game down. A phone needs one tap per rally: the side that won it. The court TV does the rest.
Starting a match
- Scan the QR code on the court TV with the phone camera. The scoring screen opens in the browser, with no app store and no account.
- Enter the PIN shown on the TV. It links the phone to that court only, which matters in a hall where courts sit side by side.
- Check the details: player or pair names, and which side serves first.
- Tap the winner of the first rally. The TV updates straight away.
When the match ends and the court resets, a new QR code and PIN appear for the next booking.
What happens on each tap
| On court | You tap | The TV shows |
|---|---|---|
| A rally is won | The side that won it | One point for that side; serve indicator moves to them |
| The score reaches 20-20 | The winner of each rally | The game continues until one side leads by two |
| The score reaches 29-29 | The winner of the next rally | That side wins the game 30-29 |
| A game is won | The winner of the last rally | Games won updates; the next game starts at 0-0 |
| Wrong side tapped | Undo | The previous score and server |
Because the serve follows the winner of each rally, the serve indicator on the TV always shows who serves next, which players otherwise have to work out.
Who scores in different sessions
- Club nights and casual games: one player, often from the side that serves first, keeps the phone on the court-side chair.
- League matches: the home team scores, or each side takes one game.
- Coaching sessions: the coach scores condition games and pressure drills.
- Tournaments and finals: an umpire in referee mode.
Leave the phone on a chair or the bench at the side of the court, never on the floor where a lunging player can stand on it.
Referee mode for umpires
Referee mode turns the phone into a console with plus and minus buttons for each side and the serve indicator. An umpire can add a point, take one back or set the server, and the court TV follows. It is the official score, entered by hand, with no sensors on court. Optical sensors that detect points automatically are included only with the Unlimited plan; without them, referee mode is how an official badminton score is kept. Referee mode in a full event is described in the badminton tournament scoreboard guide.
Intervals and changing ends
Badminton has an interval when the leading side reaches 11 points and a longer one between games, and in the deciding game players change ends at 11. Those pauses are a good moment for the scorer to glance at the TV and confirm the score with the players. Because the score is on screen, there is no need to rebuild it from memory after the interval.
Fixing mistakes
Fast rallies at the net sometimes end with a shuttle on the line and a moment of doubt. If a point goes to the wrong side, use undo: point and game undo restore the previous score and server without restarting the match.
Connection in a sports hall
Halls can have patchy Wi-Fi at the far courts. If the connection drops briefly, scoring keeps working and syncs when it returns. If a phone or TV cannot connect at all, the badminton scoreboard Wi-Fi guide explains how to cover a whole hall.
Following without scoring
Scanning the QR code also opens a live link to the match in any mobile browser. Team-mates waiting for their match, parents in the balcony or the tournament desk can follow it from wherever they are. Player names and photos used for a match are temporary and are removed when the match ends.
What you need
Any modern smartphone with a browser. Each court needs a TV or display with internet and a streaming app or HDMI input. Licences are per court: Starter ($44/month) for one court and one sport, Pro ($134/month) for up to five courts and all eight sports, Elite ($224/month) for up to ten courts, and Unlimited at $1,299 per court one-time, with no term limit and optical sensors included. See the pricing page. The general scoreboard remote control app guide compares phones, tablets and remotes.
Frequently asked questions
Do players need to download an app to score badminton?
No. They scan the QR code on the court TV and enter the PIN; the scoring screen opens in the phone's browser.
Does the app know the 20-20 and 29-29 rules?
Yes. It requires a two-point lead from 20-20 and awards the game to the side that wins the 30th point at 29-29.
Does the TV show who serves next?
Yes. The serve indicator moves to the side that won the last rally.
Can an umpire use it?
Yes. Referee mode gives plus and minus buttons for each side and the serve indicator.
What if someone taps the wrong side?
Use undo. It restores the previous score and server without restarting the match.
