## Description

MOA Scorer turns a photo of your printed sighting target into precise group measurements — no ruler, no math.

Shoot your group on a supported grid target, snap a photo with your phone, enter your distance, and MOA Scorer reads each diamond and reports:

• Extreme-spread group size in both MOA and inches (center-to-center)
• Point-of-impact offset from your aim — windage and elevation — to help dial your zero
• A clear annotated image of every group

Because the target grid is a fixed physical scale, your group size in inches is exact regardless of range, and true MOA is computed from the distance you enter.

SUPPORTED TARGETS
• Action Target SI-13MPD "Rifle Sighting Target"
• Thompson Target HALO 4643 "Scope Alignment"

BUILT FOR PRECISION RIFLE
Tuned for centerfire and rimfire precision shooting (roughly .17–.30 caliber), including tight, overlapping groups.

YOU'RE IN CONTROL
Auto-detection does the work, but you can fix anything: tap into any diamond to add or remove a shot, or drag the aim point to the true center — group size and sight adjustments recompute instantly.

MOA Scorer runs entirely on your device. Point, shoot, photograph, measure.
