GroupScope
Target Practice Shot Tracker for Android
Stop squinting downrange. Photograph your target after a string and GroupScope detects every bullet hole, measures your group in MOA or millimetres, and builds a session log over time — no internet, no account, just data.
Features
Auto Hole Detection
On-device computer vision detects bullet holes on standard paper targets, including centre-ring shots.
Group Measurement
Measures group size in MOA, milliradians, or millimetres. Tracks spread, centre-to-centre, and extreme spread.
Session History
Every session logged with date, rifle, distance, and group stats so you can track progress over time.
Camera or Gallery
Capture from your camera or load from the gallery. Works with your existing target photos.
Fully Private
No photos or session data ever leave your device. No account, no cloud, no tracking.
Works Offline
All detection runs on-device. Full functionality at the range with no signal.
