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 multiple screen app. No matter what you're doing, you can do it with Principle.

Design For Web, Desktop and Mobile
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.

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.
