Zero Helper takes the guesswork out of zeroing a rifle, carbine or air gun. Choose your zero • Tell it how you shoot (close range, general purpose or precision) and it recommends zero distances for your velocity and sight height • Compare where each zero peaks and where it comes back on target See the whole trajectory • A chart of your point of impact from the muzzle out to 1,000 yards, with near and far zero marked • A table of drop at common distances • Show my work: every step of the calculation, so you can check it Dial it in • Measure how far your group landed from the aim point, and the click calculator says how many clicks to turn, up or down, left or right • MOA and MIL turrets, any click value, in yards and inches or meters and centimeters Print true-scale targets • MOA and MIL grid targets for Letter, A4 and 24Ɨ36 posters, sized for the distance you shoot • Bullseye rings, crosshair and size check bars, with your rifle's details printed on it Keep a log • Save each rifle with its caliber, velocity, optic and units • Log range sessions, maintenance and zero changes for each rifle, plus a journal for range days • Export a backup and import it on another device Yards or meters, inches, centimeters or millimeters, feet or meters per second: pick your units for the app or for each rifle. Everything stays on your device. There's no account and no ads. Trajectory figures are estimates from a simple model. Always confirm your zero with live fire, and follow your range's safety rules.
