AI Tennis Coach

Prop up your iPhone, film 5 shots: your estimated score out of 100, the flaw that keeps coming back, every shot in slow motion on your video.
Forehand, backhand or serve. iPhone on a steady support, from the side or from behind: nobody has to film you.
3 free analyses, then a 7-day trial. No video ever leaves your iPhone.

HOW IT WORKS
1. Set your iPhone from the side or from behind, 5-10 m (15-30 ft) away, the whole player in frame. Pick the stroke and your dominant hand.
2. Hit 5 shots: audio countdown, automatic stop. Or import a video. The video analysis runs after filming, on your iPhone.
3. Read your report: an estimated index per shot, every shot in slow motion, and your #1 flaw when the same flaw shows up on several shots.

WHAT THE APP LOOKS AT, NO SENSOR
Forehand and backhand: shoulder turn, knee bend, loop, contact point in front of you if the ball is found, weight transfer, steady head, follow-through, racket speed estimated from the wrist. Serve: stance width, knee bend at the trophy position, racket drop behind the back, leg drive, arm extension, trophy-to-contact rhythm. Footwork: active feet, recovery. One- or two-handed backhand recognized.
Not looked at: the ball (speed, spin, trajectory), the toss, the grip, the match. Only forehand, backhand and serve are analyzed.

WHAT YOU GET
• A SCORE OUT OF 100 PER SHOT: the estimated technique index, the session average, your personal best.
• YOUR #1 FLAW, EXPLAINED: one priority, chosen among the flaws that keep coming back on your shots, with the drill to work on it and the pre-recorded audio coach when a clip exists. Otherwise, the app doesn't make one up.
• GUIDED SLOW MOTION: every shot from 0.25× to 1×, skeleton traced, a pause on each remark long enough to read it, an arrow to the body part concerned, "≈" measurement.
• THE 14-DAY PROGRAM: one short cue a day, then two filmed sessions to check whether the flaw comes back. "Fault beaten?" review, dated before and after.
• COMPARE TWO SESSIONS of the same stroke and the same view, lined up on contact, one card per remark, dated before / after.
• LEARN WITHOUT FILMING: 26 lessons (forehand, backhand, serve, footwork) with a solo drill, a glossary and the stroke library.
• A SCORE CARD TO SHARE: your score and your flaw, with no image of you.

WHAT THE NUMBERS ARE WORTH
Everything is estimated from a 2D video: centimeters, degrees and km/h carry "≈". Unreliable marker: the app says so or hides it. The index is not a ranking. It's an automatic analysis that we correct and improve continuously: it can be wrong, and it tells you what it can see.

THE OFFER

YOUR VIDEO STAYS ON YOUR IPHONE
Your video is analyzed on your iPhone and only leaves it if you choose Share. The app does send usage and purchase events, never your video or the content of your analyses, to advertising measurement tools, and asks for iOS tracking permission. Details in the privacy policy.

WHO IT'S FOR
Club and recreational players, from beginner to competitive, who want to improve their forehand, backhand or serve, add to their training or progress on their own. One stroke per session, filmed from the side (more complete markers) or from behind, iPhone set down and still, iOS 17 or later.

Film your next 5 shots.
