That's the real screen. Watch it arm itself, or tap ARM GATES to run it again. Demo run: times are simulated.
Three moves. Then you just run.
The camera watches a line across the lane like a tripwire. Frames are analyzed on the phone and never leave it.
Phone on a stand at the line
Point the camera across the lane. A cone marks the far end of the run.
Tap ARM and hold still
The phone reads the scene and sets its own sensitivity. For reaction drills it then waits a random 1.5–4 s and flashes GO.
The crossing stamps the time
Cross the line and the clock starts. Cross it again and it stops. Every rep is saved to that athlete.
Reaction light and stopwatch.
The phone on the stand is also the reaction light. The instant you cross the line it calls a direction, a color or a number — so you can't pre-plan the run. Then it times your return.
Left or right — a cone each side, go to the one it calls.
20 drills. Ten need only one phone.
Every drill comes with a setup diagram, step-by-step instructions and a one-tap load into the timer.
