Apexa: Tennis Serve Coach

Your serve, measured and broken down like a coach would — right on your phone.

Film your serve or import a clip. Apexa tracks the ball from toss to bounce, measures your serve speed, and puts you side by side with a reference serve. Then it tells you the one thing to work on first, and how.

WHAT YOU GET • Serve speed, serve type (flat, kick, slice) and where it landed, from behind-view clips • Ball tracking — with the ball's path traced • Compare against a reference serve with an overlay, or set your own best serve as the reference • Frame-by-frame serve breakdown with your top fixes — a clear cue, why it matters, and a drill • Share clips with your speed and serve type on the video • Consistency scores and progress charts, per camera angle

HOW IT WORKS

1. Record with the guided camera (side or behind view, portrait or landscape) or import from your library
2. Apexa finds every serve and tracks the ball, the speed and each phase
3. See your numbers, compare against the reference, then get your top fixes

MADE FOR PRACTICE COURTS No sensors, no lab. One phone, one serve, honest feedback. Works from the side or from behind the baseline — each angle on what it can actually see. Your video stays yours.
