Principle

Principle makes it easy to design animated and interactive user interfaces. Whether you're designing the flow of a multi-screen app, or new interactions and animations.

Built for the Biggest Imaginations

There are a lot of things you might want to design: a short animation, a slick interaction, or an extensive multi-screen app. No matter what you're doing, you can do it with Principle.

Animation

Principle's timeline makes it quick work to illustrate the perfect bounce, ease, and pop.

Interaction

Want to design a totally new interaction? Principle gives you the freedom to experiment without limiting you to pre-defined transitions.

Multiple Screens

It's a breeze to design the flow of a multi-screen app; and when you're done you'll have a bird's-eye view of all your screens.

Totally New, Yet Immediately Familiar

With artboards, magic animations and a timeline, using Principle will give you Déjà vu.

Pick Up Where You Left Off

Import your designs from Figma or Sketch to breathe new life into them. And if you make changes, importing again will intelligently merge your work.

Design For Mobile, Web, and Desktop

Choose a device preset or enter a custom Artboard size to design for your favorite platform. Hover events and mouse wheel scrolling make it easy to make web and desktop prototypes that feel like the real thing.

Share Your Designs

Share your design to the web with a single click for viewing on Windows, Linux, macOS, Android, and iOS. Friends can interact with your design right in their browser without having to install anything.
