How to Use the Measure App on the iPhone

* This post is part of iPhone Life's Tip of the Day newsletter. . *

One of my favorite iPad and iPhone features is the handy Measure app. The Apple Measure app uses augmented reality (AR) to function as a tape measure and level all in one. You can use this free tape measure and ruler app as long as you have an iPhone SE, the iPhone 6S or later, a fifth-generation or later iPad, any iPad Pro, or the seventh-generation iPod Touch. In this tip, we'll go over how to use the Measure app on the iPhone and iPad as you would a tape measure or ruler; we'll cover how to use the level tool in another tip. Let's get started learning how to use your iPad or iPhone as a tape measure with Apple's free Measure app.

  3. You'll see instructions on the screen to move your device to start; when you do, you'll see a white dot in a circle appear.
  4. Position the white dot over the place you'd like to start your measurement, tap the plus sign, move your device to the point where you want to stop measuring, and tap the plus sign again; you'll see a dotted line as you move your iPhone or iPad.

  5. To start a new measurement on the same object, move the plus sign to the new location, and repeat the process.
  6. If you'd like to measure from the endpoint of your last measured line, tap the plus sign while the white point is over the previous endpoint, then move your phone again to create another measurement as before.
