Zeroing a red dot at the range usually means doing MOA-per-click math in your head. Red Dot Zero does it for you:
enter where you're standing and the distance you want to zero at, tap where your group actually landed, and the app
tells you how many clicks to turn — left or right, up or down.
How it works
1. Current range The distance you're shooting from right now.
2. Desired zero The distance you want the optic zeroed for, e.g. 25 or 50 yards.
3. The goal A pulsing red dot shows where rounds must hit at your current distance to be zeroed at the desired one.
4. Real-world check Fire a group, then tap the target grid where the bullets hit.
5. Adjust Get the exact clicks for your optic, e.g. 57 Left, 70 Up.
