According to data released by Piper Jaffray analyst Gene Munster (via Fortune), iOS device owners (people who own the iPhone, iPod touch, or iPad) are, on average, downloading 61% more apps this year than they were in 2010. 61% is equivalent to 83 apps downloaded in 2011 versus 51 apps in 2010. "Smartphone users are showing an increasing appetite to use apps to add features to their phones," Munster writes, "and iOS has the leading app ecosystem."
In addition, people are paying more for their apps. The average selling price for an app is up 14% in 2011, following an 18% decline in 2010. The most likely reason for this is because of the demand for iPad apps - iPad apps are generally more expensive than iPhone/iPod touch ones. Finally, Munster notes that 82% of the apps in the App Store are free to download.
Apple announced last week that the App Store has crossed 15 billion downloads from over 200 million iOS device owners worldwide. In addition, the Cupertino-based company revealed that there are 425,000 apps in the App Store and 10,000 of which are native to the iPad.
