Konjur3D enables a designer to model and paint 3D/2D assets or create games on the move. The App combines precise hard surface and CAD modelling functions like extrusion and lathe with clay sculpting and texture editing features. The combination of engineering precision and organic modelling provides an enormous creature space to explore. It also has an integrated, visually scriptable game engine to create new experiences. A designer can explore several objects independently and then combine them into a complex project assembly or basic game. Konjur3D supports exports into the GLTF, USDZ (for Augmented Reality) and STL formats. It is intuitive, fast, cautious with storage and includes detailed help functionality. Support for export to AR viewing is included. For some features, the app is best used with the Apple Pencil to ensure sufficient accuracy in design.

Verdict
The clearest difference is price: SpinFire XR at Free against Konjur3D's $14.99. SpinFire XR also leads on iOS requirement (13.0 vs 15.6). Konjur3D's advantage is update cadence (every 3 weeks vs every 5 months). On ads, in-app purchases and device support there is nothing between them.
