How it works
Photograph your target, set the scale using a known reference like the target's own dimensions, and tap each hole. Atlas calculates your group size in inches and converts it to group MOA, the number that actually lets you compare a group at 100 yards to a group at 300 yards on equal footing.
It works completely offline. The photo and the math never leave your phone unless you choose to share the result.
Why it matters
Group MOA is something you can track over time, compare across loads, and actually trust.
