Where to put the phone
On your back with arms up and knees over the hips, phone low and at a three-quarter angle.
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
Extend opposite arm and leg toward the floor, bring them back. Every return counts.
What makes the counter wait
The moving arm must straighten. A short reach with a bent elbow does not close the cycle.
Alternating movements are counted on every drive. A repeat on the same side is still counted, it is just not ranked, and the recap shows “alternate sides” as the advisory.
One tip
Slow is fine. The counter waits.
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 →
