I currently use Adobe Acrobat X on a PC to measure the area and perimeter of items on a digital photograph. Would like the same functionality to measure area on iPad Pro.
I don't think so, but I'm sure there's some non-Adobe app somewhere that can be had for a few bucks and it may even support fancy stuff like live measurements through the camera.
A colleague thought that new Adobe Acrobat DC Standard still has this measurement function. Not sure yet but I don't think this runs on iPad. Besides, don't really want to spend $120+ per year to have this simple function. Still searching the app world with little success.
