Serve Analyzer

Side on · Portrait

Film one serve from the side. Your video never leaves your phone — everything is measured right here in the browser. You get the handful of things worth fixing, a practice plan, and the numbers behind it. It cannot see the racket or the ball. Free. No account needed.

    Stand your phone upright about 15 feet to your side, level with your hips. Whole body in frame with room above your head for the reach. One serve.

    Why this takes a minute

    Your video is read frame by frame on your own phone. It never travels to our server, is never stored, and is never seen by anyone — including us.

    There is no database and no account. Only about a dozen anonymous numbers, like joint angles and timings, are sent to be turned into coaching. Close this page and even those are gone.

    Most apps like this upload your video and keep it. We think a video of your kid belongs to you.
