How it works

Three steps.
No timing gear.

If your phone can see the gate, it can time your laps.

1

Phone beside the gate

Stand it next to the gate, camera in line with it.

2

Fly

Tiny whoop in the living room or 5" at the field.

3

Every lap, timed

A beep on each crossing. Your times, read out loud.

TRIGGER COUNTED

The camera sees the drone cross. That's a lap.

Every trigger is saved, frame by frame, so you can check any crossing later.

Features

Everything after
the beep.
