About a third of the top grossing apps in the Apple App Store are now making their money through the sale of virtual goods within the application after being free to download, according to research done by tech blog GigaOm.
Freemium applications are making a good bit of money. In January, mobile analytics firm Flurry said that the freemium games it tracked generated revenues of $9 per user per year, on average. In June, that number had risen to $14.66 per user per year. Previously, these games were generating around 99 cents to $1.99 per user per year. 34 of the top 100 apps are free, but make their money through in-app purchases of mostly virtual currencies as well as other premium features, according to GigaOm’s report.
Apple takes a 30 percent cut of all purchases made within applications. That’s the same amount that Facebook, another large host of social games (including Zynga’s Farmville), charges its game partners.
Apple’s App Store now has around 300,000 apps for sale and for free download. And the App Store is growing by around 1,000 apps every day. The Android marketplace, which has applications for phones running on Google’s Android operating system, only has around 113,000 applications according to some metrics.（source:venturebeat）
