iOS 12's new Measure app is simply not accurate. Don't count on it

I think this post is better off linking to the original (Kirk’s): https://www.kirkville.com/apples-measure-app-and-accuracy/

It took me a full minute to figure out how to get to it from loopinsight, and I don’t think loopinsight provides any additional “insight” at all...

I guess eventually they could train it with a database of "known objects" so it knows how large they are? There must be a finite amount of things that people want to measure, right?

And even if there are novel items, Siri could ask "please put a coin/drink bottle/shoe in the picture".

In order to determine accuracy, one must first figure out how it works. I could grok the level, but for measuring dimensions, in playing for few minutes in my office yesterday I never got it to do anything but tell me I’m doing it wrong. It’s not like the user manual is all that thick.
