Where to put the phone
Whole body in frame with headroom above you. The phone must see the feet leave the floor.
Stand at roughly 45° to the phone. The counter still reads the cycle from the front or the side; the angle only decides how much technique detail the camera can see.
What closes a rep
Squat, jump, land, settle. The rep closes on the landing.
What makes the counter wait
A squat with no flight is not a jump squat. Grounded cycles are refused so the count stays honest.
Because this is a jump, a cycle with no flight is refused. That is one of the three physical impossibilities the counter checks; nothing else can refuse a count.
One tip
Land softly and let the knees bend. The counter waits for you to settle before it looks for the next cycle.
After the set
Every set ends with the same recap: reps counted, time, pace, the longest run, pauses, whether the second half held up, and the camera angle the phone actually saw. Technique detail is measured for the recap and never used to refuse a rep. Why we count and do not grade →
