Interfere is an iOS-exclusive generative drawing tool for creating mesmerising Moiré patterns, interference structures, entangled geometries, and algorithmic artworks. Instead of drawing lines manually, you shape evolving geometries through an interactive generative system. Add and move control points across the canvas while the engine continuously generates layered variations, emergent structures, and flowing interference patterns. Interfere combines tactile interaction with controlled randomness, allowing every composition to evolve in unexpected ways while remaining fully explorable and editable. Features: • Create generative Moiré and interference patterns • Control line density, curvature, randomness, spacing, and thickness • Move, add, and remove control points in real time • Export high-resolution JPG images and vector graphics • Continue your work in Illustrator, Photoshop, or 3D software • Designed for artists, designers, illustrators, tattooists, and experimental creators Interfere can also be used as an educational and exploratory tool for studying interference phenomena, optical illusions, repetition, and emergent visual structures inspired by mathematics, geometry, and generative art. – Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
