Overview
Principle is a macOS app for designing animated, interactive UI - the micro-interactions and motion that static mockups can't convey. Designers import from Sketch or Figma and add timeline-based animation and screen transitions to prototype how an interface actually moves. Its one-time license is a refreshing break from subscription pricing, and it competes with Framer, ProtoPie, and After Effects for motion work. The constraints are clear: Mac only, and a niche feature set focused on animation rather than full prototyping. Best for motion designers and UX
