ShadowSwing turns your iPhone into a swing trainer for tennis, padel and pickleball. Grip it like a racket or paddle handle, swing, and hear the ball once the racket head is really moving: the same feedback as a mechanical training stick. A loose wrist and a whip get you there without forcing it; a slow, pushed swing stays silent. Pick your sport in Settings: the replay, the head-speed lever and the swing sensitivity all follow it. FREE HITTING Rally mode: no whip, no sound. Groove forehands, backhands, serves, volleys and dinks in your living room, the hotel room or the garage. WORKOUTS Guided drills with a coach voice. It calls the stroke and the count — "Forehands. Twenty. Go." — each swing counts a rep, and the rests are timed. Warm-ups, groundstroke ladders, serve days and cardio minutes for tennis, padel and pickleball. One workout a day is free. SHOT ANALYSIS Play one stroke and watch it replayed in 3D — a swept ribbon coloured by racket-head speed, ghost frames along the path, the string face, and the moment of peak speed. Orbit it, slow it down, and see exactly where contact belongs. The court matches your sport: full tennis lines, a glass-walled padel court, or a pickleball kitchen line. DAILY GOAL Pick 10, 20, 30 or 40 swings a day, or any number with Pro, and a ring on Home fills as you go. Free Hitting and workout swings both count, and it starts empty every morning. Turn on reminders and get one nudge at the time you choose, only on days your ring is still open. Never more than one a day. STATS Your practice adds up: total swings, sessions, workouts, days practised and your longest streak, all kept on your iPhone. With Pro, graphs show your swings per day, week or month, your racket-speed trend for each sport, a practice calendar, your stroke mix and time practised, and you can scroll back through all of it. SHADOWSWING PRO • Unlimited swings every day • Unlimited workouts, and build your own • Racket-head speed on every swing (km/h or mph) and your all-time record • Progress graphs: swings, speed trend, practice calendar, stroke mix and time practised • Any daily goal you like • Unlimited Shot Analysis replays • Dynamic hit: real tennis hits, soft to hard, matched to each swing • Every recorded sound, shuffle, and your own sounds • Fine-tune your swing sensitivity Free includes 20 Free Hitting swings, 3 Shot Analysis replays and 1 guided workout every day, first day included, plus the daily ring, reminders and your lifetime stats. Sharing replays as image or video is free. Pro is a subscription, yearly with a 7-day free trial or monthly; the app shows the price for your region. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage them in your Apple ID settings.
