GetJar, which describes itself as the world’s largest free app store, has just reached 2 billion downloads. The company, which was founded in 2004, currently offers more than 150,000 applications across a variety of mobile platforms including Android, BlackBerry, Java and Symbian.

Ilja Laurs, CEO of GetJar, said “We credit our growth in downloads to our open approach to the app marketplace. Giving developers for all platforms a free space to distribute their applications has proven popular to both developers and consumers. GetJar has become an even bigger player in a field of giants and a destination for free Android apps.”

The company also notes that a million GetJar users have connected to Facebook.
