Apple has revealed that more than two billion apps have been downloaded from the App Store.

This follows on from the 1.5 billion mark hit in July this year, a year on from the App Store's launch.

Claiming the service is "the largest applications store in the world", there are now more than 85,000 apps available and over 125,000 developers in the iPhone Developer Program.

Those apps have been downloaded by Apple's more than 50 million iPhone and iPod touch customers worldwide.

"The rate of App Store downloads continues to accelerate with users downloading a staggering two billion apps in just over a year, including more than half a billion apps this quarter alone", said Steve Jobs, Apple's CEO.

"The App Store has reinvented what you can do with a mobile handheld device, and our users are clearly loving it".
