As soon as I read the header text it resonated. My eyes went from the header to the text on the left. Then on to the screen shot.

But since the screen shot is kind of small - I tried clicking on it to get a better view. But there is no click to zoom functionality. Reviewing a larger screen shot is what would sway me from signing up or not. So either make it a click to zoom, or just post a bigger pic of the app. or something along these lines.
