    Pros: 

    Really simple to use. No need for a tutorial to start :)

    Cons: 

    The preview window is often over the main window, not easy when you're working on a laptop.

    I use Principle mostly for quick demos when I try to communicate interaction ideas with my teammates. Principle is very good for this if you're not trying to create something too fancy but really want to share your ideas. Word to the makers: Keep the good work!

@danielchooper I like what people do using Principle, but since you're selling it for $129, how one can share it's prototypes clients using Android device or web browser like Marvel or Invision? Why are you so iOS centric?

I'll definitely be trying this out for an upcoming project. If it could export ObjC or Swift it could replace my other mainstay animation tool, Core Animator.

Whipped through a couple tutorials - this thing is going to be great. And fast.

Whoa! This is impressive. Definitely the Sketch app of Prototyping from what it seems. Kudos to the team on a seemingly killer product. Excited to see where this goes.
