Mil Rangefinder

This application displays a rangefinding reticle over a live camera preview. Mil readings from the reticle can be used with the included calculator. You can estimate the range to a target if the target’s width is known, or estimate a target’s width if its distance is known. Detailed instructions can be accessed from within the application.

You can pause the video preview or reposition the reticle to obtain a more accurate reading. This app also has support for first focal plane simulation, where the reticle adapts to the current digital zoom level. In addition to the standard mil-dot reticle, other reticle styles are available. Some designs feature stadiametric rangefinding.

This app will be most useful on a device that has powerful digital zoom. It can be used with an external telescopic lens attachment, requiring only a single recalibration. This application is not intended to be used as an optical firearm sight, and attempting to do so is not recommended.
