Using data from Apple's public announcements and AndroLib (an Android app discovery tool), Piper Jaffray's Gene Munster has analyzed the mobile app market and determined that:
• Since its inception, Google's (GOOG) Android Market Place has generated about 7% of the gross revenue of Apple's App Store.
• Apple (AAPL) has about 85% to 90% market share of the total dollars spent on mobile apps.
• Only 1.3% of Android apps are paid, compared with 13.5% of iPhone's.
• Apple developers have made more than $3.4 billion since 2011, compared with less than $240 million for Google developers.
• Although Android is likely to grow its smartphone market share faster, Apple will probably maintain a 70%+ share of mobile app dollars spent over the next 3 or 4 years.
