There are almost one million apps available for the top 4 mobile device platforms, with the milestone set to be reached imminently, according to app search and discovery company Mobilewalla.

The company asserted that at 2 December 2011, there were 987,863 apps available, with an average of 2,000 apps reaching the market every day.

The majority of the total apps available – just under 60 percent – are available for Apple’s iOS platform, at just over 590,000. Some 32.5 percent target Android, with 4.4 percent for BlackBerry and 3.6 percent for Windows Phone.

Anindya Datta, founder and executive chairman of Mobilewalla, said: "the growth of apps is the fastest growing consumer segment in the history of commerce.”
