Modeler 3D vs Claydo Studio
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Modeler 3D
This app allows users to create 3D models using a programmatic approach with Lua scripting. It supports a wide range of 2D and 3D objects and operations, with export options for common file formats. Designed for powerful iPads, it aims to be a professional CAD tool.
- Lua scripting for 3D modeling
- Extensive 2D and 3D object creation
- CSG operations (union, subtract, etc.)
- 2D to 3D conversion (extrude, loft)
- OBJ and STL export
- Live model updates
- Multi-Window and Drag & Drop support

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: Claydo Studio at 2.9 against Modeler 3D's 1.0. Claydo Studio also leads on ratings volume (10 vs 1) and device support (3 vs 1). Modeler 3D's advantage is in-app purchases (none vs 1) and update cadence (every 4 days vs every 5 months). On price and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Claydo Studio sells 1 one-off in-app purchase. Modeler 3D asks for nothing beyond the download.
Claydo Studio holds the better App Store score, 2.9 against 1.0. That said, the two scores are not equally well evidenced: Claydo Studio has 10 ratings behind it against 1, so its average is the more settled of the two.
Modeler 3D ships an update every 4 days, Claydo Studio every 5 months. The most recent releases landed on October 30, 2026 and November 3, 2026 respectively.
