Chris Herbert for MacStories:

Freemium apps (free to download, but require an in-app purchase to expand the app) are growing particularly faster in the in-app purchasing paradise. Free app downloads have increased by 34% since 2010 while paid downloads only grew 7% in the same time frame. Distimo’s research only covered the Top 200 in each category, but that’s a strong selection of the App Store’s money makers.
