Time was, there was a debate as to which third-party multiplatform marketplace was top dog. Now, you'll find very few who won't point straight at GetJar when posed with such a question.

Cementing such a view, the "world's largest free app store" has just passed the 2 billion downloads mark, with Facebook the most popular app on 100 million downloads.

Consumers aren't short of choice, however, with the store now boasting a roster of more than 150,000 apps.

"We credit our growth in downloads to our open approach to the app marketplace," said founder and CEO Ilja Laurs.

"Giving developers for all platforms a free space to distribute their applications has proven popular to both developers and consumers."

GetJar claims its marketplace has apps for over 2,500 devices, covering Android, BlackBerry, Java, Symbian and the mobile web. The firm has also recently reached 1 million Facebook Connect users.

"GetJar's social aspects and free business model have been key to our growth, but even more growth is predicted," added Laurs.

"As we've seen Android interest increase, we've also seen interest in GetJar increase. With Android exclusives such as Angry Birds and Cut the Rope, GetJar has become an even bigger player in a field of giants and a destination for free Android apps."
