Research has found that Apple’s iOS dominates the app development market, with 7 out of 10 apps being designed for Apple’s iOS.

The report notes a number of reasons for Apple’s popularity with developers. One is its dominance in the tablet market. Another is the fact that developers can simply make more money out of being on iOS.

“Not only does Apple offer a large, homogenous smartphone base for which to build software, but also when developers build for smartphones, their apps run on Apple’s iPad tablets as well,” notes the Flurry report.  

“That's like getting two platforms for the price of one,” notes the report. “Apple offers the most compelling ‘build once, run anywhere’ value proposition in the market today, delivering maximum consumer reach to developers reach for minimal cost.”

As for the other benefit, monetary returns, Flurry calculates that an iOS app that: “For every $1.00 a developer earns on iOS, he can expect to earn about $0.24 on Android.”

“Running a comparison of revenue generated by top apps on both iOS and Android, Flurry calculates that the difference in revenue generated per active user is still 4 times greater on iOS than Android. For every $1.00 a developer earns on iOS, he can expect to earn about $0.24 on Android.”

The report concludes: “Android delivers less gain and more pain than iOS, which we believe is the key reason 7 out of every 10 apps built in the new economy are for iOS instead of Android.”
