As everyone else has already said, the design needs some work - the landing page, the sign up process, and the actual app. You should definitely check out some of the landing page templates and app templates at themeforest.net. At a minimum you can use these for inspiration/examples of attractive landing pages and apps.
I only played with the actual app for a couple of minutes, but it feels pretty solid...and fast. What did you use to build it?
