Zero Helper
Zero, trajectory and clicks
$9.99 · Designed for iPad. Not verified for macOS.
Pick the right zero for how you shoot, see where your rounds land out to 1,000 yards, and print true-scale MOA and MIL targets. No account, no ads.
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 24×36 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.
