Analytics firm Flurry has issued its latest analysis of the iOS and Android apps markets, including the headline prediction that app revenues on the two platforms from premium, in-app purchase and advertising will rise 60% this year to $8.7bn. The company expects that to be split 23% to advertising and 77% to premium and IAP revenue. However, there’s more to the research: analysis of how these revenues are likely to be split between the Top 100 apps on the App Store and Google Play, and the long tail. One finding: “We observe that long tail revenue explodes from earning under half of all premium and in-app purchase revenue in 2010 to over two-thirds in 2012… The age of middle-class app developer has arrived.  In this economy not only are the rich getting richer, but so too are the poor, and gaining on the rich.”
