Not every app 'clicks' instantly with users. Sending them directly to itunes might not be the best way to convert them. Have you tried sending folks to a landing page first (so can prime them on the idea, show them a cool video, etc)? The other advantage of this method is that once users are on your site (instead of the itunes store), you can get better analytics and behavior tracking (to understand when/why/where users are exiting the conversion funnel). Additionally, once your landing page is setup you can run more traditional marketing campaigns (adwords etc) to that site, and try all kinds of different ways to pitch the product to the potential users. Don't give up man, marketing isn't easy.
