I teach Blender. UV unwrapping is something the students have a lot of trouble with.

For those that don’t know, UV-less painting is usually vertex painting, where each vertex is assigned a color. In this way the resolution of the outcome is dependent on that of the model.

In the case of this app, a UV map is generated, but seems to be quite crude. Two options are presented: per-face and box. I assume box is derived from tri-planar projection. If so, then I assume that it would be impossible to assign a color to anything that is invisible to the projection, such as underhangs. I will play with it and see.
