Let's say I wanted to see what apps were downloaded over 100,000 or 1 million times. Or if I want to search for a particular app to see how it sold. Is there some app or site that tracks that?
http://www.appannie.com/ keeps track of all app's positions on apstore charts. Like here's SF IV's rank history in appstore. You'll need to sign up to see more than 30 days of data though.
