Last Monday, we went to AppJam in London, a European focused meet-up to share knowledge and learn more about developments from the major app stores. I was keynote speaker at the event and gave a presentation about application store stats, which you can find embedded below. The major findings in this presentation were:

• Apple App Store leads the pack in terms of amount of applications, having about a 100,000 applications available, compared to Android Market (14,000) and BlackBerry App World (3,300).
• Increase of amount of applications on Android Market and BlackBerry App World however will be driven by the amount of devices coming available with these stores pre-installed, and additional country support.
• Android Market has significant more free applications available, which may be caused by Google’s less strict approval process and the necessity to use Google Checkout for payments
• BlackBerry applications are about 3 times as expensive as Android’s and Apple’s. Cross-store publishers also charge higher prices for their apps on App World.
• Apple’s popularity ranking system favours cheap applications, however, most revenue is made by the more expensive applications, in spite of having less downloads than the cheap applications. The average price for the most popular applications was $2,58 in October, and $10.30 for the most grossing applications.
• When it comes to in-app purchasing, Games are most succesful at making revenue. Read more about this on TechCrunch.
• Succesful apps get more exposure on Android and App World than on Apple App Store. The average amount of days in the top 100 for the Apple App Store was only 14, while for Android and BlackBerry this was 26 and 20 respectively (October).

I would like to thank the organizers, Laurence and Tania, for the great event! I highly recommend it to anyone interested in mobile apps!
