This is also the most exciting feature to me. But, looking through the reviews, it sounds like the buggiest feature. Worst of all, they process your UIs server-side and then send the code to you. Unacceptable.

I just picked up Dapp (http://dapp.kerofrog.com.au/) and put together the first screen of an app that's been bouncing around in my head for a couple weeks. It was pretty intuitive and quick to put it together. I also confirmed that Dapp generates all its code client-side, by using the app only in Airplane mode. Looking over the code, I'm not thrilled about the coding style, but it's not bad for auto-generated code.

So I can't speak for Interfaces (I wasn't going to drop $10 on an app that had terrible reviews about the one killer feature I need) but it seems like Dapp is a winner. YMMV.

And more importantly, it seems to skip Interface Builder. I hate that thing.

Seems more like a replacement for Interface Builder. And quite a useful one. I'd love to be able to work on an iPad interface on my commute, come into the office, and start hacking away at the actual code at my desk.

There are people who prefer to write out all those CGRects by hand? Interesting. What will you do when Xcode 4 comes out? ;)

I do. I find Interface Builder unworkable for anything but the simplest of projects: there's just too much "magic".

Agreed.
