ORIPA - Origami Pattern Editor

ORIPA - Origami Pattern Editor is a powerful mobile tool for origami designers and enthusiasts inspired by Jun Mitani's ORIPA desktop app. It allows users to draw, check, and fold crease patterns anytime, anywhere, supporting both landscape and portrait orientations for convenience. The app is compatible with desktop ORIPA, enabling import and export of crease patterns in OPX or CP formats. Users can save their work as PNG or SVG images.

Designed for users with existing knowledge of crease pattern analysis such as Kawasaki's and Maekawa's theorems, ORIPA offers features like undo/redo actions and intuitive multi-touch gestures including pinch-to-zoom, two-finger panning, and rotation of folded models. Note that it supports only 2D crease patterns with straight lines and does not teach origami design principles. Perfect for capturing inspiration on the go, even without Wi-Fi during flights or events.
