| Quick Tip

If you installed Apple’s newest version of iOS yesterday, then you may have seen an unfamiliar app called “Measure” that got installed too. (And if not, you can download it from the App Store.)

iOS 12 Measure App on iPhone

This new app allows you to use an augmented reality tape measure through the glory that is ARKit, and it’s, uh…it’s pretty darned cool. Here’s how it works: When you open the app, you’ll first have to move your device around a bit for calibration purposes…

But then it’ll ask you to point your camera somewhere.

You can get measurements on rectangles by just aiming at one, waiting until you see a yellow box around it, and then tapping the plus button.

That’s my fuse box. Aren’t you guys lucky to get to see such an exciting thing?

Once you get your measurements, you can tap any of the white boxes shown on screen to get a pop-up window that’ll let you copy the info.

If you want to measure something else—like, say, some fridge magnets—you’ll point the on-screen white dot at one side of your object, then tap the plus button to indicate your starting point. Afterward, move the camera to the other side, and tap the plus button again.

Yes, yes, I’m off to the side. That’s a reflective fridge, and I wasn’t camera-ready. In fact, I have to point out how challenging it is to find surfaces in my house that are suitable for taking pictures and aren’t gonna show a reflection of me.

I apparently own far too many shiny objects.

I take it that this is an iPhone feature and not for an iPad, since the App Store will not let download it … Perhaps that could be mentioned in the article (Hopefully somewhere near the top). Thanks!

When I click the link, it takes me to an App Store Preview that says “This app is only available on the App Store for iOS devices”, but since my iPad doesn’t have iTunes, I don’t know how to download it to my iPad ??

I see my mistake … I didn’t know that I could pull up this article under iOS (even though it is using iTunes), then select the link above to download … Unfortunately, I have an iPad Mini 2 and, while it says under compatibility that it “works on this iPad”, it also says at the top of the page “This app requires specific features not available on this device.” So “No Joy!”


Thanks for the tip. I couldnt figure out how to do rectangles.
One question. All of my measurements come out Metric. How do you change units?
