A new name. TennisAI: Swing Coach is now Tennis Strokedex. Smarter, tougher scoring. Every swing is now graded on what the body does, the things that separate a real stroke from an arm swing: • Shoulder turn: how far you rotate from the backswing through the finish • Knee bend and leg drive: how well you load and push up into the shot • Body-led swing: how much of your racquet speed comes from your trunk, not just your arm • Hand speed, measured against a fixed standard rather than your own best swing • For serves: shoulder tilt in the trophy position, leg drive and reach Every swing is held to the same standard, for every player, so your scores mean the same thing from session to session. A score in the 90s now takes a full turn, real leg drive and a fast swing. Your past sessions have been re-graded with the new scoring, so some scores will be lower than before. Your progress trend still compares like with like. Clearer coaching. "What looks good" and your focus for next time now come straight from your scores. Each session's report shows the key numbers at a glance: swing speed, shoulder turn, knee bend and finish.

New look. A new app icon made for iOS 26, with light, dark and tinted versions to match your Home Screen. New welcome tour. New players can swipe through everything TennisAI does before their first session: form scores for every swing, coaching for each forehand, backhand and serve, tracking you across the net, and hearing each hit. It ends with tips for filming your best video, then sets up your player.

Players • Keep each person's sessions, scores and progress separate on one iPhone. Switch players from Home. • Set your racquet hand so the analysis always follows the arm that swings. • Your existing sessions are kept under your first player. Much better swing detection • Finds you even when filmed from across the court, and ignores other people in view. • Times each stroke from the sound of the ball on your strings. The sound is analyzed on your iPhone and never uploaded. Coaching for every stroke • Serves, forehands and backhands are recognized and coached separately. • Serves are now scored on leg drive, reach and arm extension. Forehands and backhands get a new finish-height score. • See how each stroke type scored in every session report. More accurate scores • Knee and elbow angles are only scored when the camera can actually see them, so front-on videos no longer give misleading feedback. Also • Now supports iOS 26.0 and later.
