Principle’s timeline makes it quick work to illustrate the perfect bounce, ease, and pop
Want to design a totally new interaction? Principle gives you the freedom to experiment without limiting you to pre-defined transitions.
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.
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.
Share Your Designs
Principle Mirror for iOS lets others view your designs on their device. While designing, you can interact instantly by plugging your device into the computer. You can also export a standalone Mac app for others to view.
Lights. Camera. Interaction.
Showing your designs has never been simpler with the record feature: Export a video or an animated gif that can be shared on Dribbble, Twitter, and wherever else you’d like!
Built for OS X
Principle is powered by Core Animation, the hardware-accelerated animation engine that iOS and OS X are built on. It also includes the Mac features you love: Full-screen mode, a Retina interface, and Auto Save — so you’ll feel right at home.
