Principle

There are many things you might want to design on your Mac: a short animation, a smooth interaction, or an extensive multi-screen application. Principle is perfectly suited for accomplishing all of these tasks with ease and precision.

The Timeline simplifies the entire process, allowing you to illustrate the ideal bounce, fade-in, and reveal with remarkable clarity and control.

Want to create an entirely new interaction from scratch? The principle app gives you complete freedom to experiment creatively, without restricting you to predefined transitions or limiting your design possibilities.

It is an absolute breeze to design the flow of a multi-screen application on your Mac; and when you are finished, you will have a bird's-eye view of all your screens laid out clearly before you.

With artboards, magic animations, and timeline, using principle for mac, you will experience a powerful sense of Déjà vu — everything feels intuitive and familiar right away.

Choose a device preset or enter a custom Artboard size to build for your favorite platform. Hover events and mouse wheel scrolling make it effortless to create prototypes for websites and desktop applications that look and feel completely real. The principle app mac version includes Mirror for iOS, which lets you preview your designs directly on your personal device in real time.

While designing, you can connect your device to your Mac computer for a live preview, or export a standalone Mac application for convenient offline viewing and sharing with your team.
