In April, Apple announced that its customers downloaded over one billion apps from the Apple app store. Now, just five months later, Apple has reached the two billion mark and added an additional 50,000 apps to the store to bring the current total to 85,000 apps.
An interesting chart on the Mobclix website shows the number of apps in each of the 20 app categories. Of the 85,000 apps, there are 10,204 book apps and 5,312 education apps. The number of apps in both of these categories has more than doubled since April.
With the popularity of the app store increasing everyday and rumors that a large screen Apple tablet will hit the market early next year, Apple could make a considerable impact in the higher education market in the coming months.
