Research In Motion executivess took the stage during BlackBerry DevCon Europe on Tuesday to clear up a few facts about the company’s success with its BlackBerry App World marketplace. RIM’s new CEO Thorsten Heins said BlackBerry App World is now home to more than 60,000 applications, which is a fraction of what’s available in the Android Market or iTunes App Store, and that BlackBerry devices are among the most popular smartphones purchased in the United Kingdom. RIM’s vice president of developer relations Alec Saunders also said that there are 174 million app downloads per month, or about 6 million applications downloaded per day, The Verge reported. Saunders argued that RIM’s BlackBerry App World has 43% more daily downloads per app than Apple’s own iTunes App Store and he said App World can be more profitable as well — BlackBerry apps supposedly earn about 40% more than their Android counterparts, and 13% of BlackBerry developers have made more than $100,000 from their apps. In addition to the app figures, Saunders and Nokia’s head of Qt announced that RIM’s BlackBerry PlayBook OS now supports the Qt developer framework, originally intended for Nokia devices.
