AR tracing onto real paper, canvas, or a wall
This is the feature the whole app is built around. Aim the phone at your paper, canvas, or wall, and your reference appears as a translucent layer floating over the real surface in the camera view. You draw the proportions straight onto the paper by hand — no projector, no light box, no copying a grid square at a time. It is the one thing the free browser tool physically can't do, which is exactly why the app exists.
If you want the background on the older analog methods and where AR fits among them, the guide on how to trace a photo onto paper covers it.
