Height and Distance

This app is an obvious cash grab to present you with ads. It doesn't measure anything. I tried, while seated, to measure a space heater. It registered as 24' tall. It can't possibly use the camera, as it never asks for permission as any other app would. It's utter nonsense, and should, frankly, be removed from the app store.

It's hard to understand how to use for the first time. But after some minutes I can use it to measure my neighbor's orange tree

I need to estimate the height of a tree that is dying and has to come down. This looked like the perfect app. Unfortunately, it does not work at all. You are instructed to "aim here" and then "aim here". But you are just pointing the phone in some vague direction without any real help in the aiming, resulting in wildly in accurate estimates. I messed with this for 10 minutes, then deleted it.
