Settings

Name

Pre-filled when you save a time.

Target

Six-sevens to land before the clock stops.

Countdown

Seconds of 3-2-1 before the clock starts.

What counts as one

Every single hand alternation scores.

Travel

How far your hands must separate before a swap registers, in palm lengths. Lower scores more easily; too low and jitter counts on its own. Measured against your hand size, so it holds at any distance from the camera. With the blur assist on this is the ceiling, not a fixed bar.

Smoothing

Steadies jittery landmarks. Raise it if the count flickers, lower it if fast reps feel late.

Debounce

Minimum gap between swaps. Raise it if jitter double-counts.

Camera

Which device to capture from.

Blur & low-FPS assist

Sizes the travel threshold to the swing your camera is actually resolving, keeps counting from one hand when the other blurs out, and eases off smoothing as your reps get faster. Turn it off for a fixed, literal threshold.

Rhythm assist

Once you settle into a tempo, a swap the camera misses is filled in from the beat instead of dropped. Turn it off to count only what the camera actually sees.

Live test

Try the detector, and read your camera's real frame rate, without touching the board.

Mirror the camera

Selfie view — your right hand appears on the right.

Sound effects

Blip on every count, jingle at the finish.
