The design is nice, would be cool if you sped up the page a bit. It's a little slow (maybe that's just for me?). Also, it'd be nice if you made the iPhone picture a higher resolution.

It's obvious what problem your app is trying to solve, but it's not very clear how. The blog doesn't help in explaining this at all. The landing page is interesting and nice-looking, but it could do with some more explanation ("it's X for Y!" wouldn't hurt)
