RallyLines

One AirPod in a holder on your racket. That's the whole setup, and the racket on your screen starts swinging when yours does. THE RACKET Print the holder, snap it on, drop the AirPod in. Two minutes. • Swing Mirror: a chalk racket on a court that turns as yours does, with a trail and an estimated speed and path after each swing • The Minute: one minute a day, swing whatever you like, get three numbers back and fill a can of balls by the end of the week • Ghost: keep your best swing as a ghost, then try to match it, 0 to 100 a swing • The Ladder: a rally in your living room. Meet each ball on the beat, climb ten rungs, then play the Club Champ • Swing-Off: send a friend your minute and see who matches your tempo more often • 3D Replay: scrub every swing of a session and compare two side by side Racket tracking estimates timing, rotation, path angle and speed so you can compare your own sessions. It does not measure ball speed, ball spin or impact location. Every game has a labeled demo you can try without the accessory. THE SCORE • Tennis: deuce or no-ad, tiebreaks, match tiebreaks, and who serves next, tiebreak rotation included • Pickleball: side-out or rally scoring, games to 11, 15 or 21, and the score called out loud: 4–2–1 • Win probability after every point, plus break point and match point calls • Live score on your Lock Screen and in the Dynamic Island • Score from Apple Watch, the phone, your voice or a nod with AirPods in THE FENCE Lean the phone on the fence and it watches you hit.
