Range Finder uses input from your device's accelerometer to calculate how far away you are from an object, or how high something is.

Simply select between height mode and distance mode and enter the distance from the ground to your device (or distance from a vertical plane to your device if in height mode) and begin measuring.

Range Finder provides live on-screen distance updates every second which allows for multiple distances to be measured quickly and effectively.

You can now calibrate Range Finder to work accurately on a hill of any degree so you can determine the distance to an object no matter what the terrain.

**To avoid measuring the distance from your device to the ground, use your height as the distance from ground and hold your device so it is level with your head.
