About this app
Leave the laser at home.
RangeFinder estimates distance using your phone's camera and any known-size reference object — a steel gong, a soda can, a golf flagstick, a fence post. Point, bracket, read. No laser hardware required.
HOW IT WORKS
This app is built on stadiametric ranging — the same principle behind the PU scope mounted on the Mosin-Nagant sniper rifle. If you know an object's real height and how big it appears in frame, geometry gives you the distance. Your phone's camera field of view is known precisely, so the math is exact, not a guess.
Point your camera at a reference object near your target. Bracket its height with two adjustable lines. The app instantly calculates distance using your phone's known field of view — corrected automatically for uphill or downhill angle using the gyroscope.

Independent evidence report
Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
What we measured
Each line is a measurement published as a measurement, never a verdict.
Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
