How to Use the Level in the Measure App in iOS 12 on iPhone

Apple's new operating system, iOS 12, introduces a new, useful measurement app that also includes a level (the Compass app no longer has a level feature).

I've written about how to use the augmented reality (AR) tape measure portion of the Measure app in a previous tip, so now it's time to go over how to use the level feature; let's get started!

Now find the surface you'd like to check for level and place your iPhone on it. You can hold it in portrait or landscape mode. When the surface you're testing is level, you'll see 0° and a green screen.

If the surface you're checking isn't level, the screen will be black, and you'll see how many degrees plus or minus it's off from level.
