## What is GroupTrace Shot Measure?

GroupTrace Shot Measure is a paid, local-first measurement bench for precision shooters, handloaders, coaches, and range teams.

Import a real target photo from the system photo picker or work on the built-in neutral target field. Set scale using two endpoints of a known span, then mark each impact center. Keep sighters separate from counted shots without losing them from the visual record.

Calculate extreme spread, mean radius, centroid, horizontal and vertical envelope, plus MOA or MIL at the recorded distance. The geometry uses the actual points you mark and a saved calibration—not a guessed rectangle.

Attach firearm, ammunition, caliber, distance, units, and range notes to every session. Duplicate a complete session as a revision and compare saved groups in a compact load history. Export point-level CSV with normalized coordinates, sighter flags, extreme spread, and mean radius.

All target images and records remain in private local storage unless you explicitly export them. No login is required. The app has no subscription, in-app purchases, ads, analytics, tracking, cloud sync, AI processing, or developer-server upload.
