TERRA-CONFIRM
The rifle logbook for shooters who want proof, not vibes. Photograph your target, tap your shots, and Terra-Confirm measures the group, tags the cold bore and turns the offset into exact turret clicks — then logs the lot against the rifle, the load and the weather.
Get it free on Google PlayThree steps to a confirmed zero
No measuring tape, no maths at the bench. The camera does the geometry.
Photograph
Shoot your group, photograph the sheet. A Terra-Target QR sets the distance and grid automatically — or scan it live, pick markers manually, or use any paper with a known reference.
Tap your shots
Mark each hole on screen. Group size in MOA or MIL, centre-to-centre, with the cold bore tracked separately so the first round from a clean barrel can’t lie about the group.
Dial the correction
Terra-Dial converts the offset into turret clicks for the scope on that rifle — its actual click value, not a generic table. Save the session and the zero status updates itself.
Cleaning & barrel life
Carbon and copper countdowns you can tune per rifle, round counts, barrel-life tracking and full cleaning history.
Sessions that tell the truth
Every range visit is a session — load, rounds, the conditions as their own fields, and where you shot from: bench, prone, sticks, kneeling or offhand. Wind excuses become data, and bench groups stop flattering your field shooting.
Best Load
Compare everything you’ve shot through a rifle and let the groups decide what it actually likes.
Ammo inventory
Rounds on hand per load, drawn down as you shoot, with low-stock warnings before the weekend, not during it.
Licences & permits
Expiry tracking with 60-day reminders and a photo of the card itself — season never starts with a lapse.
Pre-range check
A packing checklist that runs before each session — ears, eyes, chamber flags, targets — so a two-hour drive is never wasted.
