Modeler 3D is in the tradition of OpenSCAD and JSCAD a programmatic 3D modeling tool. In contrary to those two, the well known Lua-script language is used. Primary target devices are the latest, powerful M1 iPads, which calls for professional, native CAD tools. This need shall be fulfilled by Modeler 3D. Honestly speaking, Modeler 3D is not there yet, but will quickly evolve. Designs can be exported as OBJ and STL in high quality and full resolution. Features: - 2D objects: Circle, Square, Rectangle, Isogon, Text, Arbitrary Path, Sketch consisting of multiple paths - 2D modifiers: translate, rotate, scale - 2D object operations: union - 3D objects: Cube, Cone, Sphere, Cylinder - 3D modifiers: translate, rotate, scale, center - 3D object operations: union, intersection, subtract, xor - 2D to 3D: extrude, loft - 2D applied to 3D: Pocket - Native CSG engine written in Swift - Export: OBJ, STL, PNG and code - Live updates of computed 3D models - Color support: - Multi-Window Support - Drag And Drop between Projects and from File Manager We are looking forward to your feedback.

Verdict
The clearest difference is rating: 3D Model Viewer at 4.2 against Modeler 3D's 1.0. 3D Model Viewer also leads on ratings volume (328 vs 1) and device support (3 vs 1). Modeler 3D's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price and iOS requirement there is nothing between them.
