More than 40 billion apps have been downloaded from Apple's App Store, with nearly half of app downloads occurring in 2012.
Apple said a record 2 billion apps were downloaded in December last year.
"It has been an incredible year for the iOS developer community," Eddy Cue, Apple's senior vice president of internet software and services, said in a statement.
"Developers have made over $7 billion dollars on the App Store and we continue to invest in providing them with the best ecosystem so they can create the most innovative apps in the world."
There are currently more than 500 million active accounts in the App Store. The App Store was launched in 2008, and it hit the 1 billion download mark in 2009.
