iPhone 12 Pro and 12 Pro Max, thanks to their built-in LiDAR Scanners, have a handy feature that lets you quickly (and surprisingly accurately) measure someone’s height — without the need for third-party apps.

iOS 12 adds a brand-new Apple app to your iPhone and iPad. It’s called Measure, and that’s exactly what it does. With it, you can use your iPhone’s camera to measure distances instead of breaking out a tape measure or ruler. Also, the level tool has moved from its old home in the Compass app, and now lives in Measure. Let’s see how the new app works.
