Principle

Principle is a design software optimized for the design of interactive and animated user interfaces. It's ideal for app developers, programmers, and graphic designers. Principle is designed for Mac users and comprehensively covers every potential design necessity. Whether you're designing an interaction, a multi-screen app, or a short animation, Principle features the tools you need. You can customize the software to suit your unique design needs. Principle uses a timeline to make animation easy. You can use the timeline to create the perfect bounce or pop. In addition, you can design totally customized interactions without being limited to pre-defined transitions. It's easy to design the flow of a multi-screened app, and when you're finished you can view all screens at once. You can use Principle to design for web browsers, desktop applications, and mobile systems. There are device presets if you have a specific device you're designing for. Additionally, you can enter a custom Artboard size to design for a specific platform. There are mouse wheel scrolling and hover events that allow you to create web and desktop prototypes that function like the real thing. You can also easily share your Principle designs by using the Principle Mirror for iOS, which allows other people to view your designs on their mobile device. You can interact instantly with your design by plugging your mobile device into your computer. It's also possible to export an individual Mac app for others to see. Hundreds of design teams use Principle for their work. Teams that work for Apple, Cartoon Network, Facebook, Google, Amazon, Microsoft, Netflix, and hundreds of other big name corporations have all found success with Principle's streamlined approach to design. Principle has a free fourteen day trial, excellent for developers who haven't yet settled on the design tool they want to use. Only days that you actually use the software count toward the fourteen days. The full version of Principle costs $129. Online tutorials and community resources are available, helping to minimize the learning curve and get you designing faster than ever.
