Some facts, assumptions and calculations on App Store & Google Play
In 2013, 6.1% of all app downloads (approx. 80bn apps) from all application platforms will be paid. (Juniper, July 2013). Thus 4.88bn app downloads will be paid. Assuming that the share of paid downloads is higher in the App Store than in Google Play, I add some percentage to the 6.1% for Apple, leading me to 8% for paid downloads in the App Store. I assume this figure has only slightly come down since 2012, as in proportion more free apps than paid apps have be added to the App Store since 2012.
