Principle 6.39

Principle makes it easy to create interactive and animated user interface designs. Whether you're designing the flow of a multi-screen app or new interactions and animations, Principle lets you create designs that look and feel great.

A familiar interface lets app designers present their animation designs to clients, managers, and development teams - gone are the days of hand-waving and long meetings.

Inspired by studying how some of the world's best UI designers work, Principle combines the design, animation, and interaction tools you need into a lightweight, easy-to-learn interface. Principle is retina-ready and built on the same rendering and animation system that powers OS X and iOS, so you can be confident your designs will look great in real life.

Key features of Principle include:

• Animation and interaction design: Enable custom animations, smooth transitions, scrolling, swiping, and managing multiple states without being limited to predefined effects.
• Multi-screen and device support: Design flows for multi-screen apps and choose device presets or custom artboard sizes for multiple platforms, including web, mobile, and desktop.
• Import and sync with design tools: Seamlessly import designs from Figma or Sketch, with intelligent merging as designs are updated, allowing for seamless workflow integration.
• Preview and share: Interactive preview window simulates touch and mouse interactions; prototypes can be shared via web link for viewing on multiple platforms without installation.
• Export options: Export animations as videos or animated GIFs for easy sharing on social media and design platforms.
