I’m Emotionull, the maker of Clayground. It’s a standalone Quest sculpting app for building characters and other forms from volumetric clay, with no PC needed.
You can add, carve, pull and smooth the clay, paint it, use mirror or radial symmetry, and keep parts on separate layers. There are stamps, frame-by-frame animation and live-recorded motion too. Models can leave the headset as GLB, OBJ or STL, and animated work can export as GLB.
The current update adds a virtual camera for taking pictures of your sculpts, Save As, and safer saves. The Meta listing supports Quest 2, Pro, 3 and 3S. It describes the app as free in Early Access and also lists in-app purchases.

If you try it, I’d love to know how the brush control feels in a first session, especially placing small details versus moving larger shapes.
