App analytics firm Flurry said that, based on an analysis of downloads of its tools for iOS and Android, developers have shifted their emphasis to projects using Apple’s platform over the Google operating system.

At the start of the year Flurry found that more than one-third of apps integrated with its analytics were for Android, but this figure had fallen to around a quarter based on its estimates of new app projects for the current period (Flurry has around 55,000 developers using its tools in their apps – around 25 percent of all apps downloaded from the App Store and Android Market).

The company attributed the shift to events including the launch of the iPhone by Verizon Wireless and Sprint in the US, and the launches of the iPad 2 and iPhone 4S during the course of the year.

Flurry also said that “anecdotally, developers consistently tell us that they make more money on iOS, about three to four times as much,” which would explain the popularity of the platform. Prompted by this, it explored its data from apps available in both iOS and Android forms, discovering that “for every US$1 generated on iOS, the same app will generate US$0.24 on Android.”

It was noted that the “largest single factor that appears to impact developer support for [Android] is the consumer’s ability to pay.” The size of the Flurry-enabled project base has nearly doubled during the course of the year, which the company said was fuelled by anticipation ahead of the iPhone 4S launch, and the upcoming Christmas holiday sales period.
