How to film

  1. Stand the phone behind the baseline, facing the court.
  2. Place it slightly off-center from the player.
  3. Keep the whole body and the racket in view for the full swing.

Common questions

The app asked me to choose the contact moment. It finds contact from the sound of the hit. If the sound is unclear (wind, other courts, a muted video), choose the moment the racket meets the ball yourself.

"We couldn't see the swing clearly." Film from behind with the whole body in view, in good light, at normal swing speed.

Do my videos leave my phone? No. Analysis runs on your iPhone and results are saved only there. See the privacy policy.

How do I delete my data? Delete an analysis from its result, or delete the app to remove everything.
