Flurry Analytics has released a new report showing that, in terms of revenue, Apple's App store is number one and closely followed by Amazon's App store, while Google's Play Market landed in last place. The report states that for every $1.00 in revenue that Apple makes from it's App store, $0.89 is spent at Amazon's App store, and $0.23 in Google's Play Market. The data was gathered between mid January 2012 and the end of February from about 11 million active daily users. It's no surprise that Apple's App store is number one, but what is surprising is how fast Amazon has managed to grow their app store given its relatively small life span.
Something to keep in mind, the data collected for this study was only from in-app purchases and did not include apps that were purchased or ad-supported apps, both of which are the majority on Google's Play Market.
