A badminton scorekeeper that calls the score out loud. Rally to 21, best of 3, and zero setup.
Modern BWF badminton uses rally scoring: whoever wins the rally wins the point, regardless of who served. Games go to 21 points, win by 2, with a cap at 30 — so 29-29 is sudden death and the first side to 30 takes the game. A match is best of three games. This is the same format used at the Olympics and on the BWF World Tour.
For the full breakdown — including the 1.15m serve rule, service court geometry, lets, faults, and how to keep score in doubles — read the complete badminton scoring rules guide.
Every badminton score app in the store assumes you want to log a season, follow friends, post to a feed, and pay for a premium tier you'll never use. RALLY assumes one thing: you're about to step onto a court and you want a scoreboard that works the instant you open the page. No signup. No tutorial. No notifications.
The whole screen is two enormous tap targets in red and navy, easy to read from across a sports hall with the lights overhead. Voice calls mean you never have to squint at the phone between rallies. Rename players in two seconds. Undo one tap. Reset one tap. The page caches itself for offline use after the first load — most sports halls still have terrible Wi-Fi.
Club players who turn up for an hour of doubles after work and want an honest count without writing on a damp piece of paper. Parents running junior training sessions. Coaches who want a visible scoreboard everyone can see from the sideline. School PE teachers running end-of-term tournaments. Anyone who has ever lost the score at 11-10 in a tense game and felt a small amount of shame.
If you umpire at BWF-sanctioned level, RALLY isn't a replacement for an official score sheet — but it's perfect for every match that isn't one.

Yes. RALLY uses BWF rally scoring: first to 21, win by 2, capped at 30 (so 29-29 becomes sudden death at 30). Best of 3 games is the default. Read the /rules/badminton-scoring page for the full rules.
Not yet. AI Ref is currently optimised for squash and pickleball singles. The shuttle moves much faster than a ball and needs its own model training, so badminton support is on the roadmap but not yet shipped.
Yes — the scoreboard works identically for singles and doubles. Just rename the teams at the top of each side and tap whichever team wins the rally.
