Voice

The count is spoken by the phone's own speech engine. On Android, a language it lacks is read with the wrong accent, or not at all: install the voice under Settings, System, Languages, Text-to-speech output, Google engine, Install voice data. The button above says a number in the chosen language, so the check is one tap.

Pose

How sure the pose model must be before it draws a skeleton. Raise it when the app counts reps the athlete did not do, which happens while somebody walks into shot and the model draws a leg on the floor behind them. Lower it if the app stops seeing an athlete who is plainly there. Above about 0.95 it turns the real athlete down too and nothing is counted. Reload the judge board after changing this.

Recording

This browser cannot record video, so the judge board cannot keep a set's video.

On by default. The judge board records the camera while it runs, the picture as the camera sees it, without the lines or the skeleton. When the camera stops, a button under the start button saves the video. The phone holds a set's video in memory until the next one replaces it. If the browser asks whether the site may download multiple files, allow it, or a second save from the same page does nothing.
