Affiliate marketing in the App store: Combination of Kieskeurig and Restaurant.nl

As the number of applications available for download through Apple’s App Store continue to swell, the need has grown for a more efficient way to filter through the 100,000+ options across the multitude of categories.

As a result, app discovery tools have become a flourishing segment of the iPhone app market: Chorus, Yappler, AppsFire and Sidebar. In addition, Apple recently unveiled a feature called App Genius that makes recommendations based on past purchases.

Chorus, which is free, allows you to see which apps that your friends have downloaded and rated highly. It then uses algorithms to make recommendations based on those preferences.

The businessmodel of Chorus: the company gets a small kickback each time it sends a purchase request for a paid application to Apple.
