Reckoner - Scoreboard

Reckoner keeps score for many sports — each by its own rules.

Pick a sport, start a match, and Reckoner tracks the rules as you score: deuce, serve rotation, games and match, and side-out. No more keeping different rules straight in your head.

It currently supports Table Tennis, Badminton, Pickleball, and Racquetball.

WHO IT'S FOR · Anyone keeping score at a club or gym · Players who mix up each sport's rules — deuce, serving, games · Anyone who wants a scoreboard that knows the rules, not a plain counter or mental math

WHAT YOU CAN DO · Automatic rules — deuce, serve rotation, games and match, side-out · Screen modes — a single screen, a face-to-face view for two, or a big landscape scoreboard you can read from afar · Remote — connect another phone and score or undo from across the court. It connects with a code between nearby devices, with no internet or account. · Sound, voice, and haptics — turn on only what you want · Undo — take back the last point · Record — finished matches are saved automatically; on iPad, see the list and details side by side · Rules per sport — see how the app scores, with links to the official (federation) rules

ON IPAD · Reckoner fills the screen on iPad — great for standing it on a table.

PRIVACY · No account needed. Everything stays on your device.

Pick a sport, and leave the rules to the app.
