A bit more info on what exactly this "app maker" is/does would be quite helpful. The "about us" and "help" section of the site don't give much useful information. Given some more information, I'd be happy to sign up.
it's a website that generates apps for small business and big groups. Apply for a beta key in the registration, and there are floating clouds that follow you explaining how everything works and how to get your app into the app store.
