Principle makes it easy to create animated and interactive user interface designs. Go beyond static mockups and create living designs that express feeling. Whether you're designing the flow of a multi-screen app, or fun new interactions and animations, Principle lets you create designs that look and feel amazing.
Inspired by studying how the world’s best user interface designers work, Principle combines the design, animation, and interaction tools you need in a lightweight, easy-to-learn interface. When you're done, you can show animated designs to clients, managers, and the development team.
How Licenses Work
A license includes one year of updates. After a year you can renew your license if you want to continue getting updates and using the latest version of Principle.
Using Licenses on Multiple Devices
Purchasing with a quantity of more than one will give you one license key that can be used on more than one device. The devices can be your colleagues' or your own. You can also add capacity to an existing license.
Buying For Someone Else
Licenses can be purchase for someone else by clicking the gift icon at checkout. The recipient will get an email with the license keys, and you’ll get an email with the invoice.
After purchase you can get your invoice from the License Manager
