About this app
Zero faster. Think less. Shoot with confidence.
ZeroMate instantly translates your point-of-impact offset into the exact number of windage and elevation clicks you need on your scope, red-dot or iron sight. Whether you work in meters & centimetres or yards & inches, this free app does the heavy lifting—so you never reach for a calculator (or scratch your head doing mental math) at the range again.
Why you’ll love it
Scope click calculator – just enter distance-to-target and impact offset, tap Calculate, and dial the suggested clicks.
Metric ⇄ Imperial on the fly – seamlessly mix cm/m, in/yd, MOA, mil, IPHY.
Pre-loaded optic database & presets – choose popular scopes, red-dots and iron sights (or quick presets such as 1/3 MOA, 1/2 MOA, 0.1 mil).
Works offline once loaded – rock-solid even at remote ranges with no signal.
100 % free & ad-free – no paywalls, no subscriptions, no data harvesting.
Privacy-first – ZeroMate stores nothing about you, your firearm or your sessions; all calculations happen on-device.
How it works
Enter or select your optic’s click value (e.g. 0.25 MOA or 0.1 mil).
Type the distance to target and your shot group’s horizontal/vertical offset.
Tap Calculate to see the exact clicks for windage & elevation.
Dial, shoot, confirm—done.
Built for
Hunters, competitive shooters, instructors and armourers setting up new optics.

Anyone who wants to spend more time shooting and less time scribbling numbers.
“ZeroMate turned a chore into a 2-minute routine. No more phone calculator at the bench!”
