Google Play, formerly the Android Market,apparently isn’t pleasing developers in the same way the iOS App Store or even Amazon’s Appstore are. According to data from Flurry Analytics, Amazon generates nearly four times more revenue from in-app purchases than Google Play does.

Flurry compared the iOS App Store, Amazon Appstore and Google Play by first setting iOS revenue to 100 percent since it generates the most. Then the competitors were given their own percentage to represent revenue by comparison. Amazon Appstore came in at 89 percent and Google Play came in at a sad 23 percent. Flurry notes that another way to describe this would be to say that for every dollar iOS apps generate in revenue, Amazon’s app marketplace generates $0.89 and Google Play brings in $0.23.

What’s worse is that in December, the Android Market was generating 24 percent of what the iOS App Store was earning. Though only slightly, overall revenue from Google Play apps has dropped.

Flurry obtained this data by analyzing top-ranking apps from each of the app stores in the study. The apps collectively average 11 million daily active users. The revenue was then monitored over 45 days spanning from mid-January to the end of February 2012.

When TechCrunch asked Peter Farago, VP of Marketing at Flurry Analytics, what he thought Microsoft’s Windows Phone could bring to the table in the future, he was rather optimistic. “We believe that Microsoft + Nokia have a lot of the key assets to succeed, from a powerful OS, hardware know-how and, most importantly, building robust third party developer support. We are bullish on their progress,” he responded.
