Every feature in the AR drawing app.

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.

All 82 composition and drawing overlays

The app carries the complete Grid Maker Pro overlay library — golden ratio, Loomis head, dynamic symmetry, perspective, sacred geometry, and the rest of the eleven categories. No other tracing app ships a composition set this deep. You can draw over a grid on its own, or lay a grid on top of your own reference photo and use both together.

The same 82 overlays run free in the web tool; browse them by type in the grid library.

Lock-in-place tracking that holds when you move

Tap once to anchor the reference. From then on it stays pinned to your real surface using the device camera and motion sensors, so it keeps its position and scale when you shift the phone or lean in for detail. This lock-in-place tracking is the difference between AR tracing and just holding a photo steady — it is what makes the proportions stay true across a whole drawing session. Move too quickly and tracking can drop; the app says so and asks you to move slowly back toward the surface. No headset and no external hardware are involved. Automatic anchoring needs a phone that supports Google Play Services for AR; on other phones the app offers manual tracing instead.
