TennisPose3D

Set your iPhone to the side and hit forehands. TennisPose3D tracks your body from the camera, turns it into a 3D skeleton, checks every swing, and gives you a short spoken tip on what to fix. Practicing alone, between lessons, or doing shadow swings at home, you can see your own form in 3D. WHAT IT DOES AI turns the camera's 2D skeleton into a 3D skeleton in real time Finds each swing automatically and tells forehands, backhands and serves apart Measures knee bend, shoulder turn, follow-through and weight shift on every forehand Speaks a short tip during practice, only for issues that keep coming up ("Bend your knees", "Turn your shoulders more"), so you never need to look at the screen After practice, review how often each issue came up and go through every swing Watch a short clip of each swing and spin its 3D skeleton with your finger to see your form from any angle Works for right- and left-handed players HOW TO USE Place your iPhone to the side with your whole body, head to feet, in view Pick 1 or 5 minutes and tap Start Hit forehands and use each tip on the next swing Afterwards, review your issues and swings in Records TIPS Film from directly to your side, about 2 to 4 m (7 to 13 ft) away, for the best accuracy Bright light keeps the skeleton steady Shadow swings without a ball work too PRIVACY All video analysis runs on your iPhone.
