iPhone · iPad · Apple Watch · Live on the App Store
Turn the iPhones and iPads you already own into a BWF badminton scoreboard, a multi-angle slow-motion replay system and a tournament desk — with an Apple Watch app to keep score from your wrist. Settle a contested call yourself in seconds with ¼× slow-motion loops and frame-by-frame stepping — 100% offline, with no subscription.
It does not make line calls for you. It gives players and umpires the footage to make the call themselves.
Mount one phone at the side of the court and it is your scoreboard and replay camera. Wear an Apple Watch and you can score without walking to the phone between points.
iPhone · Official BWF scoring
Tap or swipe up on a side to award the rally, swipe down to take it back. Tap VAR Review and the last rally plays straight from the rolling buffer — no waiting for an export — in a continuous ¼× slow-motion loop you can step frame by frame. The server, service court, 11-point interval and change of ends are tracked for you in singles and doubles.
Apple Watch
Start a match on your iPhone and the Apple Watch app shows the same team names — “Us” and “Them” unless you choose your own or pick a preset like “Smashers vs Retrievers” — with the live score, the server and the service court. Tap or swipe up on a side to give it the rally, swipe down to undo. It is a remote for the match on your phone, not a separate scorer.
Run entire club nights, school championships, and regional opens from a single master iPad. Umpires scan a QR code to connect their iPhones and stream live scores back to the central desk without a Wi-Fi router.
iPad · Shuttle Vision Pro
Follows every live court at once, across up to 7 connected devices. Calculates standings in real time based on official BWF tie-break rules (Matches Won > Game Difference > Head-to-Head > Point Difference > Points Ratio). Organizers hold master overrule authority, fixture generation (Round Robin, Single and Double Elimination, Open Court Queue), and CSV export capabilities.
1 to 3 phones · No router
Drift-compensated clock sync gives you up to three replay angles of every rally, with no router needed.
Set up in under 60 seconds with zero network configuration.
Mount the phone — don’t hold it. A replay is only as useful as the footage behind it. Held in your hand, the phone adds its own shake to every frame and rolling shutter bends fast movement, so a close call is harder to judge in slow motion — and Living Room Practice, which follows the shuttle frame to frame, loses it more often. Any steady mount works: a tripod, a clamp on the net post, or the phone propped against a bag.
1. Mount your iPhone horizontally on a tripod at the umpire chair or side of court (~1.2–1.6m high) so it sees the full court.
2. Tap Start match on Home. Sides start as “Us” and “Them”; to type your own names or tap Preset names, open Match setup first.
3. Tap or swipe up (+1) to score. Tap VAR Review at any moment to watch a contested rally again in slow motion and make the call yourself.
1. Host taps Tournament → Multi-Phone Mesh, picks Duo or Pro, then taps Pair with Other Phones to show the court QR code.
2. On the second phone, tap the QR icon on Home and scan that code, or enter the code shown beneath it. Guests never need Pro.
3. Place the phones at opposing net poles (~40cm high). Both cameras synchronize clocks automatically over direct P2P.
1. Open Shuttle Vision on an iPad and tap Tournament → Tournament Desk & Standings → Create Tournament.
2. Paste your player roster and generate Round Robin, Single Elimination or Open Court Queue fixtures.
3. Open the Master Desk and tap Connect Court Phone. Umpires scan the code, choose their assigned court, and begin live scorekeeping.
1. The Watch app comes with Shuttle Vision. If it isn’t on your watch, open the Watch app on your iPhone and install it from there (watchOS 10 or later).
2. Start a match on your iPhone, then open Shuttle Vision on your watch. It shows the same names, score, server and service court — the first-named side is yours.
3. Tap or swipe up on a side to award the rally, swipe down to undo. Keep the phone nearby: the watch is a remote for the match on the phone.
