## What is 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. Pose tracking runs on the iPhone; nothing is recorded or uploaded.
• Serve coach: each serve rated 0 to 100 for legs, trophy position, extension and finish, with a slow-motion replay
• Groundstroke coach: forehands and backhands scored on preparation, contact, low-to-high path and finish
• Footwork drill: 60 seconds of split steps and bounces, counted
• Shadow Rally: the app calls forehand or backhand, you swing, the camera times you
• Weakness Finder: what's costing you points, and a 7-day plan to fix it
• Game Plan: a pre-match brief built from your own matches

THE BOARD
• Your RallyLines Rating for tennis and pickleball, with your expected win % against each opponent
• A weekly league, global and friends rankings, and friends added with a 6-character code
• Challenge someone to a serve-off or a week race
• Every match on one scorecard: serve and return stats, the Clutch Index, shot maps and a Stats Lab

## Version history (last 5 releases)

### 1.6.3 — 2026-10-27

Leagues, clips, your watch and a new look.

• Weekly Swing Leagues: earn XP from The Minute, the Ladder, Ghost and racket sessions, climb from Bronze to Diamond every week.
• Streak freeze: a 7-day streak earns a freeze for the day life gets in the way. Optional 8 pm reminder.
• Apple Watch + AirPod together: wear your watch on the racket wrist and both count your swings live. Pause or finish from your wrist.
• Fix my tracking: mark "Missed a swing" or "Not a swing" and it learns your swings.
• Swing Clips: Court Cam video cut per swing, with the 3D racket beside it. Export a 15-second best-swings reel.
• 3D Replay compare: two swings side by side, synced at contact, six camera angles.
• Apple Health and Game Center: sessions close your rings; leaderboards and achievements for the games.
• A new look drawn from the court, and two-pane layouts on iPhone Duo.

Every racket number comes from the AirPod's motion and is marked est. No AirPod yet? Every game has a labeled demo.

### 1.6.1 — 2026-10-23

New App Store screenshots and small polish. Everything from 1.6 is here: the Racket tab, a 3D racket that moves as yours does, guided calibration, Daily Swing, Rally Quest, Shadow Swing, 3D Replay and more, with one AirPod on your racket.

### 1.6 — 2026-10-22

Fifteen new things to do with one AirPod on your racket, all in the new Racket tab.

• Racket tab: the app opens on your racket with one big button: Connect, Align & start, Resume.
• A guided one-minute calibration that spots a loose mount, grades the result and redoes only the step that failed.
• Swing Mirror: a 3D racket that moves as yours does, with an Align button so it matches exactly.
• Leaving a racket screen and coming back now always works.

• Shadow Swing: record your best swing as a ghost, then match it, scored 0–100.
• Daily Swing: a 60-second swing check with a streak and a share card.
• Swing-Off: challenge a friend to beat your 60 seconds, by link.
• Rally Quest: a living-room rally game with levels, a Daily Rally and a Weekly Boss.
• 3D Replay: scrub every swing of a session in 3D and export a 15-second video.
• Trails Wall: every session becomes a print of its swing trails.
• Swing Report: your week in one page, one fix, and a 7-day plan.
• Live Courtside: share a link and friends watch your racket move live, then leave you voice notes.
• Swing Counter: a giant live count for the phone propped by the court.
• Warm-Up Fingerprint: your swing shape today against your usual.
• Consistency Trend: how steady your swing is, week by week.
• Hot Streak: a chime when five swings in a row match your best.
• Lesson Mirror: coach and student rackets side by side.
• Dink Counter: dinks and resets at the kitchen, plus a Dink 50 drill.
• Swings on your Watch and Lock Screen.

Faster everywhere: tab switches, opening a session and going back are much quicker, and the background no longer animates. RallyLines no longer asks for Motion & Fitness until you open a racket feature.

Every racket number comes from the AirPod's motion and is an estimate. No AirPod yet? Every feature has a labelled demo.

### 1.4.1 — 2026-10-21

Your first practice now needs only your phone. Open RallyLines and tap "Start my first practice" — no account, no accessory, no payment first.

• Plain-language results: each practice ends with what happened and one next step, then leads to Practice 2 of 3 and a one-tap partner invite.
• Every coaching fact says where it came from: your tags, the score, a coach note, or a motion or camera estimate.
• Sessions and Coach each open with one clear card. Everything else is a tap away under All tools.
• Shared links now open the item they promised — practice, challenge, club night or plan — and show who sent it.
• Fixed: opening a shared link while the app was closed could crash it.
• Your sessions, history and exports stay yours on every plan, including after a membership ends. A dropped connection no longer hides your plan.
• Racket Mount (Beta) shows a short safety note before your first mounted session.
• Clearer English and Spanish wording throughout.

Racket tracking uses one compatible AirPod secured to the racket. Motion-based estimates help you compare your own sessions; they do not measure ball speed, ball spin or impact location.

### 1.4 — 2026-10-18

A clearer way to play.

• Four simple tabs: Start, Practice, Progress and More.
• Start racket tracking, score a match or save a practice straight from Start.
• Guided racket practice now works before your first saved session. Learn a comfortable reference, then work through three focused blocks.
• Racket drills and insights include timing challenges, Swing Trail and Progress Ledger.
• Simpler AirPod setup, a larger court-side practice display and clear pause and finish controls.
• Calmer coaching language, voice previews and read-aloud controls.
• Searchable tool categories, clearer English and Spanish wording, and improved large-text layouts.
