Basically useless unless the surface is flat and uninterrupted. – Ruler App + AR Tape Measure Review

The system won’t register the plane of a door frame, so I can’t measure the space, even along the top edge. It identifies the plane of the surface quickly when I point the camera at the floor, so if you want to measure things like that t works fine. Unfortunately for me, yet another AR measuring app that falls short and is being uninstalled.
