How do I use the Measure app in iOS 12?



  Public beta version of iOS 12

With iOS 12 you can leave your tape measure behind the kitchen drawer.

Once you've got iOS 1

2 installed, you'll notice a new Apple app called "Measure." This app uses augmented reality as a tape measure or ruler and measures objects with the camera of the phone around you.

The next time you need a rough measurement of your coffee table instead of scrawling through the drawers for 10 minutes your tape measure, take your phone instead.

Each time you open the app, you are prompted to move the phone so it can analyze the area you want to measure. Hold your phone so that the camera points to the object you want to measure, and move the phone around until you see a white circle with a dot in the middle.

Align the white dot with a corner of the desired object, then measure and press the white button with the + sign in the middle of it. If the app detects an object, the dot will often "hang" on a corner as you approach it.

After pressing the Measure button, move slowly to where you want the measurement to end. Once there, press the measurement button again. If you fail, there is an undo button at the top of the screen and a delete button.

Repeat the measurement of another side by repositioning the white dot and pressing the measure button. You can repeat this process as many times as you like.

Tap the shutter button at the bottom right to take a picture of the measurement.

Square Footage

I did not find the right conditions to activate the app, which detects four corners of an object and highlights it in yellow (see above), but when it does, it's pretty cool.

If it happens, a Just press the Measure button to immediately calculate the length of each segment and display the square area in the center.

If the app does not automatically detect the full extent of an object, you can still use it for the square footage estimates. Just measure each side of the object and then let the app work its magic.

Adjusting a Measurement

If you measure something and you do not have the start or end point in the right place, do not start over. Instead, simply drag the point to the right place with your finger.

Precautions and Tips

Note that the Measure app is by no means precise enough to use cuts on a piece of wood or important decisions based on size. It's more of a tool to get a pretty good idea of ​​how big or small something is.

In my tests, I found that the app is between a few centimeters in one measurement and a more consistent half inch. I found that the closer I got the phone to the start and end point, the more accurate the app became.

When I tried to measure how wide my office door is, I started to stand about 5 feet away and mark my points. The app came back with 32.5 inches, for a door that is 36 inches wide. So I moved about a foot off the door and re-measured, and the result was 35.5 inches. That's okay for me. (You can change the default setting between Imperial and Metric by opening the iOS Settings app and searching for fairs.)

Copy a measurement to the label with a tap followed by copying in the pop-up window.

Oh, there is also a level

Before I forget it, there's also a level in the new Measure app. It's the same level that has been in the Compass app for the past few years.

Switch to the layer by selecting the Layer tab at the bottom of the screen and then placing the phone on the surface you want to align. Once the two circles are aligned and 0 is read in the middle, the interface goes from black and white to green.
