Sighting in a rifle usually means walking shots in square by square, a box of ammo at a time. Here's the short version instead: shoot a group and photograph the target once. Mark your aim point, type the target's size, and the app finds the target and every bullet hole on its own — measures the group in real inches and tells you how many clicks to turn, for your optic, your load, and your distance. About half a minute, all on the phone. Then it can work backwards from that group to true your muzzle velocity, so your dope matches the rifle you actually own.
One photo after shooting. The app finds the target face and every hole itself, rings your rounds — skipping old holes and the backer — and converts point-of-impact error into exact turret clicks for your optic's click value. Dial it, then confirm with a group.
Back out true muzzle velocity from a photographed group at a known distance.
See your actual reticle at magnification with real subtensions, so you know your holdovers before you shoot.
Drop, wind, and energy in MOA, MIL, or clicks, with environment pulled from your phone's sensors.
Primary optic, 45° offset, laser, and irons — each with its own height over bore and its own zero.
Every measurement and every ballistic solution runs on the phone. No account, no signup, no ads, no tracking, no signal required. The one network call in the app is the optional weather auto-fill you tap.
Every preset traces back to a manufacturer's published figure. Where a manufacturer doesn't publish something, the app says so instead of inventing it — and where no maker publishes a subtension table under a given reticle name, that reticle is drawn from the closest documented pattern rather than from made-up numbers.
Print these at 100% on any home printer. The four corner markers let the app set the photo's scale and find your aim point automatically — the most accurate way to use it. Free to download and use, app or no app. There are also distance guides for sighting in at 25, 50, 100, and 200 yards.
No. Everything runs on the phone. The one optional network call is pulling current weather, and only if you tap the button.
No account, no email, no login. Your rifles, loads, and photos never leave your device.
No. It trues your velocity from observed drop, which is a good practical estimate, not a chronograph reading.
It can estimate range from a photo of a known-size object. That's useful at short and mid range, not a substitute for a laser rangefinder.
