With the introduction of ARKit in iOS 11, Apple put a stake in the ground in the mobile Augmented Reality race. Some of the best early AR apps used your phone to measure linear distances—a digital tape measure, if you will.
With iOS 12, Apple is expanding it’s Augmented Reality capabilities with ARKit 2, and has built-in a new utility app called Measure to show what Augmented Reality can do. It’s a simple app that reliably measures linear distances, and obsoletes some of those early, simple AR measuring apps.
