The second set of sobering figures come from app store analytics firm Distimo, which last week published research which claims that 80% of all paid apps and nearly 20% of all free apps on the Google Market have been downloaded less than 100 times.
Only two paid apps on the market have been downloaded on the more than half a million times worldwide, compared to Apple's App Store where 6 apps hit that milestone in two months from US sales alone.
This means developers are finding it more challenging to turn a profit on the Android Market using a one-off fee model, Distimo said.
But the report notes that developers have pursued an ad-funded model, with feedback from one high-profile adopter, Rovio, indicating that this can be successful. It adds that the introduction of in-app billing should also give developers more opportunities to earn from the Market ecosystem.
