Just a recommendation: You should tell me why I'd want to your application instead of something like Freckle (http://letsfreckle.com, what I'm currently using). Freckle's design is gorgeous, the workflow and UX is retarded good (including the popup tracker) and multiple project handling is awesome. It's also cheaper. I think a small section with text including an answer to "Why is this better than X?" goes a long way to increment the signup rate.
