Note the Apple Measure app is available in from App store and runs on other phones including for example an iPhone 13 Mini (I vaguely even remember it working on an earlier phone but won't swear to that).
What's not available on non-Pro phones (etc) are:
• Horizontal and vertical guide lines appear when measuring large objects for easier and more accurate measurements.
•
Instantly measure a person’s height from the floor to the top of their head, hair, or hat.
• Save measurements from a single session, complete with screenshots, so they’re easy to access and share whenever you need them.
As per Features section for this app on the App store:
Turn your iPhone or iPad into a tape measure with Measure. Measure enables you to quickly gauge the size of real objects, a person’s height, and it can automatically provide the dimensions of rectangular objects. Features • Draw lines and estimate their length in both horizontal and vertical...

It's easy enough however to trace a line on non-Pro phones so not sure how great the "instantly" feature is.
How accurate it is (and whether Pro phones are more accurate than non) I can't say. Quick tests with the 13 Mini nailed the diagnoal of my TV and gave a reasonable value for my door's height. Several measurements of room width/length were off by several feet.
As far as utility value, I'll stick with measuring tape. As far as entertainment value, I'd put it somewhat below Animojis.
