1. Put the phone on the floor
Lean the phone against a stable object a few meters away, low and facing you. Keep both arms in view. The movement guide recommends a front view; follow the framing instructions in the app if your room needs a different angle.
2. Get inside the four corners
Open Push-Ups in CaliCam. The setup stage shows four corner brackets and one instruction: your whole body inside. Head, shoulders and hips are what matter; the feet may leave the frame. When the skeleton is steady, the countdown starts on its own.
3. Do the push-up
Lower your shoulders at least halfway toward your hands, then press back up until your arms straighten. The rep closes at the top. A shallow rep, a lifted hand, or a cycle the camera could not follow does not count; CaliCam shows the reason.
4. Read the recap
When you stop, the set shows the count, time, pace, pauses and reasons for reps that did not count. Knee push-ups are not a separate camera-tracked movement in the current public catalog.
- Feet out of frame: fine, the counter follows shoulders and hips.
- Backlight from a window: move the phone so the light is on you.
- A rep not counted: check that the chest actually lowered and the elbows locked back out.
