Apple Insider posted a news story that the App Store has reached a half-million approved apps

148apps, Chomp and Chillingo on Tuesday sent out a large infographic to commemorate the achievement, revealing that the average price for an application is $3.64, while 37 percent of all applications are free. Though Apple is believed to have approved more than 500,000 applications, the amount of active applications available in the App Store is roughly 400,000.

The stats also reveal that it would cost $891,982.24 and over 7 terabytes to get all applications available in the App Store. And unsurprisingly, top-selling paid application by far is Angry Birds, which has held the No. 1 spot for 275 total days.
