AR Graffiti is our version of Tilt Brush for Augmented Reality. The problem with AR painting apps that use GPS is that you cannot save paintings in precise positions in the real world. For e.g. if you were drawing a mustache on a statue, there's no way to save that mustache unless you can detect the statue and precisely position content relative to it.

Placenote SDK provides an easy way to add mapping and precise persistent content placement to your ARKit app. This project shows you how to build a persistent painting app with ARKit and PlacenoteSDK.
