Before you play. Set the phone in landscape behind one baseline, with the whole court in frame. Where to put your phone covers the thirty seconds of craft involved.
Record. One continuous take is ideal. A few separate clips work too; a session can hold several videos. Record your play as it actually happens. Nothing needs trimming or tidying.
Upload. Off court, start a new session and add your footage. Wifi and mobile data both work; wifi is quicker and spares your allowance. Keep the app open until the upload finishes, especially on a weak signal.
Let go. Once the session shows as processing, it is with us. You will be told the moment it is ready: your shots, their types, their speeds, your first numbers. If this is your first session, it arrives as your premiere.
If something is not behaving, Fix a problem is written symptom by symptom, starting with My upload is stuck processing.
