Research firm Distimo put together a series of posts to find out how many downloads it takes to get to the top of the Apple App Store free app rankings. Just how much does it take a free app to hit the top 10 free apps in the Apple App Store? it would require about 30,000 downloads per day in the U.S. alone. And how about the #2 or #3 top free app? About 200,000-300,000 downloads! That is nuts! [Distimo]

Analytics firm Distimo did some research on the Apple App Store and the Google Android Market. There are about 72,000 paid Android Market apps and 211,000 paid Apple App Store apps. Distimo also reported that Apple tends to have bigger application hits.

According to application store analytics company, the Android Market is expected to out-grow the Apple App Store in terms of size by the end of July 2011. research2guidance, another app store research firm based in Germany, agrees with Distimo but believes that the change will happen in August. Research2guidance expects that the Android Market will hit 425,000 apps by August. In April 2011, the Android Market grew 28,000 apps and the Apple App Store grew by 11,000 apps. This does not necessarily mean that developers are making more money on the Android Market. Google has yet to release the number that they have paid out to their developers. [MobileBurn]

According to a report by application analytics company Distimo, about 57% of all Google Android applications are free. Whereas 28% of iPhone applications are free.
Distimo also found that over half of all mobile apps across the Android Market, AppleApp Store, Nokia Ovi Store, and Palm App Catalog is priced under $2. BlackBerry App World is not part of this list because apps are not allowed to be priced under $2.99, unless it is free. Below are a couple of analysis charts from Distimo:
