Moving into a new space and wondering if your old desk will fit? Most people would suggest you measure the desk with a measuring tape, but if you're running iOS 12 you don't need even need that!

The new Measure app allows you to use augmented reality (AR) to measure lines using only the back camera of your iPhone. The Measure app works pretty well in a pinch, but it isn't always 100 percent accurate, plus its still beta software, meaning more tweaks to the Measure app may come before iOS 12's official launch in September.

However, if you're interested in checking it out, here's how to use it.

Apple occasionally offers updates to iOS, watchOS, tvOS, and macOS as closed developer previews or public betas for iPhone, iPad, Apple TV and Mac (sadly, no public beta for the Apple Watch). While the betas contain new features, they also contain pre-release bugs that can prevent the normal use of your iPhone, iPad, Apple Watch, Apple TV, or Mac, and are not intended for everyday use on a primary device. That's why we strongly recommend staying away from developer previews unless you need them for software development, and using the public betas with caution. If you depend on your devices, wait for the final release.

How to measure an object in the Measure app

As of right now, the Measure app can only measure straight lines, and since it uses the back camera, the more light you have, the better results you'll likely have.

  1. Launch the Measure app from your Home screen.
  2. Move the white dot to your start point. It will try to snap to corners when the camera comes across one.
  3. Tap the + button to select your start point.

  4. Move the white dot to your endpoint.
  5. Tap the + button to select your endpoint.
  6. Look at the final measurement located in the middle of the line. You may need to step back to see it.

How to use the level in the Measure app on iPhone

The level tool in iOS 12 is the same as it has been in past version of the iOS, except its been moved to the new Measure app.

  1. Launch Measure from your Home screen.
  2. Tap Level.

Horizontal level

  1. Place your iPhone flat on the surface of the object you're trying to level off.
  2. Tilt your iPhone in all directions until you hit 0 degrees and the screen turns green.
  3. You can tap once to turn the black screen red, and it will stay that way until your iPhone is level, at which point it'll turn green.

Vertical level

  1. Hold your iPhone against the object that you're trying to vertically level.
  2. Tilt your iPhone in all directions until you hit 0 degrees and the bottom half of the screen turns green.
  3. If you want to then take another measurement off of that angle, tap the level once. You'll then see red as you stray away from the angle you were on. This can help you measure 90-degree and 45-degree angles.
