Principle app — easy animated app designs

I first discovered Principle in April after seeing a prototype tweeted out by Daniel Hooper, its creator.

  
Daniel was kind enough to invite me into the beta and it was truly eye-opening: somebody had finally made something as simple and powerful as Keynote for interaction design (with on-device previews!).

Even if you’re not a designer or Creative Cloud expert, you’ll be able to build your interaction idea in Principle in no time — perfect for product managers and other interdisciplinary roles.

But instead of telling you about it, go and download the trial and take it for a spin yourself. There’s not much of a learning curve, but do check out some of the tutorial videos — there’s so much you can do once you’ve grasped a few concepts.

I like it enough to be quoted on the website
