It's the first and the unique marketplace for source code of iPhone/iPad apps. Developers can sell sourcecode of their apps multiplie times. It's a best way for developers to earn extra income from products that brought too few cash in AppStore. Ability to buy source code of existing app means buyer will be able to ship new product to AppStore in several days, not monthes.
App developers can just buy source code of several apps and mix the code to create another app. The site uses FaceBook.com for authentification, so no extra clicks and keystrokes are required to start selling or buying the code. It uses paypal for payment and payouts. This marketplace has a 20% comission for keeping the code, reviewing it (to guarantee that source code uploaded by the seller is indeed complete source code of the app) and featuring the code in various places. The number of times the same source code can be sold is unlimited.
