It's not all that different. Although, Fries aims to deliver components just how you'd see them in a native Android app (check out Android Holo Dark theme) and employs Android UI guidelines. Most prototyping frameworks out there all look iOS-ish. That's where Fries is different.
This is really great. I was going to use Ratchet for a Android prototype but having the native UI components sets better expectations of how the app will look and fell. Thanks for putting it together
