There is Zwapp, the community, and there is Zwapp Connect, our service that helps developers reach the users that are actually interested in their app. We use our recommendation engine to match between user needs and app to drive downloads. We've tried several app download services and found the quality of the downloads very poor. By using a lot of social/app and meta data that we have build up we can target much better and help devs to drive downloads to people that are more likely to use your app. (sorry about the pitch). It is actually a tough problem to crack that involves reach, matching tons of data, providing the right call to actions and then measure the success and improve the process again.

Cool, there are also some iOS apps explicitly for "app discovery," but I still think it's impossible to break out. I read somewhere that 4% of app downloads account for about 3/4 of all app revenues.

Zwapp is one of those app discovery apps. And it is a platform for developers wanting to promote their apps to passionate app users. See : http://itunes.apple.com/app/id426360184?mt=8&ls=1
