Shapr3D

Shapr3D is a modern, intuitive CAD app designed primarily for iPad (with macOS/Windows versions) that uses Apple Pencil for direct, gesture-based modeling. It combines the precision of industrial CAD with a touch-first, mobile-friendly interface. It supports importing and exporting standard CAD formats (STEP, IGES) and is ideal for product designers, engineers, and architects who need to sketch ideas on the go. It uses a subscription model with a free tier with limitations.

It ranks for its innovative approach to making professional-grade parametric and direct modeling accessible on a tablet, revolutionizing mobile CAD workflows.
