Adobe has released a free preview version of its new user experience design app, Adobe Experience Design CC, for OS X 10.10 Yosemite or later. Also known as Adobe XD and first unveiled as Project Comet, the app focuses on designing user experiences for mobile applications, and the web. It's meant to help produce quick and fluid prototypes, which you can share with your colleges.

From Adobe:

Adobe XD integrates design and prototyping in a lightning-fast, fluid desktop application. The solution helps designers move seamlessly from wire-framing and design to prototyping and preview, in order to iterate quickly and craft the apps and websites that keep users coming back. This first Preview release includes focused and intuitive design and layout tools; a dedicated prototype mode for defining interactive hotspots and transitions; desktop preview mode for testing prototypes and seeing changes in real-time; and built-in sharing that enables stakeholders and teams to access prototypes in their browser, on the desktop or from mobile devices.

This preview version, Adobe Experience Design CC 0.5, already offers a solid set of features. You can download the free preview directly from the Adobe Experience Design CC website.
