Great Survey On What iOS Apps Make
252 developers filled in a survey about what their apps were making on the iTunes App Store. You can read all of the details, but bascially, few apps are making most of the money.
Only 25 percent of developers have earned more than $30,000 lifetime total revenue selling iOS games and another 25 percent of developers have hauled in less than $200. Four percent of survey respondents have earned more than $1 million in the App Store.
