The app store is now home to over 100,000 apps.
"The manufacturer says users have download some 2 billion free and paid applications across 20 categories since the store opened on July 10, 2008, equating to 20,000 downloads per application on average, or 4.15 million total downloads per day.

iPhone application tracking site Apptism Apptism corroborates Apple's claim, tallying 100,707 pieces of software at the time of writing, with 18,554 games among those. Apple's own release did not break down app count by category."
