Love the idea, will definitely try it out.

One bit of feedback I want to give is: when I'm answering questions on the iPhone app, there's a dialog that shoots up from the bottom... this is too much motion and I don't like it. Especially since there are multiple questions back-to-back, it feels a bit nauseating to see that dialog shoot up over and over.

I think a quick fade in (or no transition at all) may be better suited for that part of the app.
