An Apple customer is set to receive $10,000 in iTunes vouchers after the App Store hit 25 billion downloads.

Chunli Fu of Qingdao, China, downloaded the landmark app over the weekend, having chosen from more than 550,000 free and paid-for apps currently on the store.

He had downloaded 'Where's My Water? Free' from the App Store which was launched just three-and-a-half years ago.

Eddy Cue, Apple’s senior vice president of Internet Software and Services, said: "We’d like to thank our customers and developers for helping us achieve this historic milestone of 25 billion apps downloaded.

"When we launched the App Store less than four years ago, we never imagined that mobile apps would become the phenomenon they have, or that developers would create such an incredible selection of apps for iOS users.”

The speed at which apps are being sold is stark given that the 10 billionth app - Neon Play's Paper Glider - was downloaded as recently as last January.

Oli Christie, CEO of Neon Play, told The Independent that it helped to boost the fledgling studio and he called the growth in app downloads "staggering".

He said: “It was just over a year ago that we received the call from Apple telling us that Neon Play’s Paper Glider was the 10 billionth app to be downloaded.

“Despite being number one game in the UK and the US at the time, we were still shocked at our name being bandied around by journalists from all over the world.

"It was such an achievement for our small studio. Although we’d already had success with games like Flick Football and Golf Putt Pro, this took us to another level entirely and provided us with a great springboard for 2011.

“Everyone has got used to these huge stats associated with app downloads but if you step back and really think about it, the market’s growth has been staggering."

There were 800 apps available when the App Store opened in July 2008 but as the number of iPhones, iPod touches and iPads have risen to 315 million, so the number of apps have risen.

Wednesday's expected unveiling of the iPad 3 is set to spark another app-buying frenzy. Billions more apps have been downloaded for rival systems such as Android, Blackberry and Windows Phone 7.
