What Can 30M App Downloads Teach You? App Store Metrics and Insights
Pinch Media has analyzed 30,000,000 iPhone app downloads from the iTunes Music store and provides lots of insights into the pricing, timing, rankings of apps. Of note is the way usage drops off significantly for free apps (slide 12). Only 5% of users will open a free app after 30 days after downloading it. Makes you question the value of free.
While teh data is Apple iPhone-centric (based on how the store is designed for high turnover in the top rankings) the information should translate well for any app developer pursuing the emerging crop of app stores available for developers (i.e. the Ovi store and the Android market).
