Getting it set up, and what to do when it argues with you

Setting up the rig

Do this once, carefully, and every session afterwards takes under a minute.

Mount up and aim at a real 10 m target in your normal stance. Have someone measure floor to muzzle, and your aiming eye to the muzzle along your arm. Enter both.
Set the phone mount to your muzzle height plus the camera offset — measure to the lens, not the top of the phone.
Stand where you shoot and tape your feet. Measure 36 in from the muzzle at 45° on your shooting-arm side and tape the tripod's front leg.
Open the app, drag a box around the pistol, and let the setup check confirm the geometry. It reads the real distance with LiDAR and tells you which way to move, in centimetres.
Write your camera height on the tripod leg in marker.

Common problems

Frame rate is low: Turn depth off once the rig is set. On iPhones the depth sensor holds video to 30 fps, and muzzle sampling rate matters more during a series than the automatic distance check does.
It loses the pistol: Tracking drifts over a long string. Re-mark it between series. Even lighting on the pistol helps considerably; strong backlight does not.
Shots aren't detected: The detector listens for the sear release. On a quiet trigger, or in a noisy range, raise the sensitivity — or use the manual mark button, which produces identical analysis.
The numbers moved but my shooting didn't: Check the tripod is on its tape and the height is right. Five centimetres of standoff error shifts every millimetre figure by about 5%.
The aiming mark is the wrong size: Calibrate the screen against a ruler in settings. Points are not millimetres, and panel densities differ between models.

What the numbers mean

Every millimetre figure is muzzle movement at the shooter, not a position on a target face. The app never converts one into the other, because a camera beside you cannot resolve where a pellet would have gone — see the explanation on the home page.

The number worth watching over weeks is break disturbance. It is trigger technique with the aim removed, and it is the one that moves first when technique improves.

Requirements

iPhone running iOS 17 or later. A model with LiDAR or Face ID depth enables the automatic distance check; without it you set the standoff by tape.
A tripod that reaches your camera height at the mount.
An account is optional. The app records and reviews sessions fully offline; an account only adds backup.
