Hi, co-founder/designer here. The iPhone on our home page is actually a live demo of Prismadrop (using App.io). Appreciate the feedback - I will work to make it clearer in the future so everyone is aware it's a live demo.

I thought it was simply an animation. It would help if the frontpage told you what was going on.

If iOS apps can run in a browser absolutely any application for ant platform could run from within a browser window.
