Nobody has to remember the third number

Score by voice

Turn on Listen and say “point Blue” or “point Orange” after each rally. It keeps listening with the screen locked, and if it isn't sure which team you said, it scores nothing rather than guess.

The call, out loud

After every change the full score is spoken the way it's called on court: “four, two, one”. The voice is shaped to carry outdoors, and your music dips for the call, then comes back.

Knows the rules

Side-out scoring, first and second server, side outs, the 0-0-2 start, and which court to serve from. Doubles or singles, to 11, 15 or 21.

Mistakes are cheap

Say “undo”, or tap it, to take back the last change. Or set any score outright: “reset to Blue serving 2-3-1”. Every game is kept in History.

On Apple Watch too

Tap a team to score from your wrist, or hold the microphone and speak. Phone and watch stay in sync and call the score together. Tap scoring works with the phone left at home.

Offline and private

Speech is recognized on your iPhone, so it works on courts with no signal and your audio never leaves the device. No account, no server.

Requirements

iPhone or iPad with iOS 17 or later. Voice commands are recognized in English (US) and need a device that supports on-device speech recognition; tap scoring works on any of them. The Apple Watch app is optional and needs watchOS 10 or later.
