Help, looking for an iOS way to do this:
(highlight by using translucent mask).
I know how on a desktop... looking for mobile method. Thought maybe the "mask image" workflow in Shortcuts would do it, but I'm not seeing it.
Found one app that will do (I'm sure there are others)
Annotable
Sorry, couldn’t figure out to copy App Store link:
