RenderGenie turns your iPhone and iPad into a portable 3D model workbench. Open STL files to view, rotate, and inspect your models, run printability checks, and share reports - all processed entirely on your device. Whether you're a maker checking a model before a print, an engineer reviewing a mesh, or simply curious about a 3D file someone sent you, RenderGenie gives you a fast, private way to open and understand 3D models anywhere. KEY FEATURES - Open your model: Import STL files (binary and ASCII) straight from your device. - Interactive viewer: Rotate, pan, and zoom in real time, and switch between Solid, Wire, Points, and X-ray render modes. - Inspect geometry: Examine dimensions, measurements, and geometry details with on-device analysis tools. - Prepare & validate: Run printability and validation checks to catch issues before you commit to a print. - Reports: Generate inspection reports of your findings and share them with the native share sheet. - Fully on-device: Your files are processed entirely on your device. They are never uploaded to any server, and there's no account to create. HOW IT WORKS RenderGenie parses and analyzes your 3D model files locally using its built-in geometry engine, then renders them with native graphics. Files you open stay on your device - nothing about your models is uploaded to us. - Supported formats: STL (binary and ASCII) - On-device engine: mesh parsing, measurement, and printability checks all run locally - No cloud, no account: no sign-in, no file uploads, no server-side processing of your models Privacy policy: https://dallastechlabs.com/rendergenie/privacy
