iPhone 12 Pro and Pro Max, iPhone 13 Pro and Pro Max, and iPhone 14 Pro and Pro Max models feature a LiDAR Scanner next to the rear camera that can be used to measure a person's height instantly in Apple's preinstalled Measure app.


To measure a person's height, simply open the Measure app, point your iPhone at the person you want to measure, and make sure they are visible on the screen from head to toe. After a brief moment, a line should appear at the top of the person's head with their height measurement. You can choose to have the measurement displayed in feet-and-inches or in centimeters in the Settings app under Measure → Measure Units.

The app measures a person's height from the floor to the top of their head, hair, or hat. You can even measure the seated height of a person in a chair.

The circular shutter button in the bottom-right corner allows you to take a photo of the person with their height measurement and share it with them.

The feature is not available on iPhones without a LiDAR Scanner.

It’s just a toy - like the measure app itself. For anything important — get out the tape measure.
Obviously you wouldn’t be using this on a construction project, but if you have a LiDAR scanner the Measure app is actually pretty accurate, and is way more convenient than a tape measure if you need to measure a piece of furniture or see if there’s enough space to fit something somewhere.

I think it’s about time for another “security researcher” to come forth warning that your biometric information can be STOLEN by newer iPhones. And, while they’ve warned Apple, they’ve heard nothing back regarding how Apple plans to resolve this alarming issue.

For now, if you don’t want anyone to know your height, DO NOT LET THEM POINT IPHONES AT YOU!

Next up: People taking videos of you also have the ability to know what you look AND sound like when you’re not around!
