Microsoft: Windows Phone Store hosts more than 300,000 apps
In December 2013, the number of available apps was 200,000, while in April this year it was around 250,000 - so the Store seems to be gaining about 50,000 new applications each four months, or over 10,000 per month. Microsoft also says that over 4 billion apps and games have been downloaded via Windows Phone Store until now.
P.S.: The smartphone seen above is the Nokia Lumia 930, one of the world's first to run Windows Phone 8.1 out of the box.
