Antetype is the best, most productive tool for UI design I have ever used. It does everything, from websites to mobile apps, and it's just unbelievable how much time it saves me. There is simply no better tool out there if you're serious about UI design.

Antetype lets me try out ideas fast and iterate even faster. It's especially useful in large, long-running projects, where I can build up a comprehensive collection of widgets that can be used, reused and refined over time. If I make a change to a widget, that change happens everywhere, even in designs I made weeks or months ago. Brilliant!

I always thought using Photoshop for UI design was silly. But after using Antetype, I see that I was wrong. It's not silly. It's laugh out loud ridiculously absurd. Stop using a photo editing app for screen design and start using Antetype, made specifically for UI designers by UI designers.

I've found Antetype to be a really clever tool. And refining a design from a loose idea to a polished prototype is what Antetype's widgets are made for: change a property, update the widget and presto, every instance is up to date.
