Free apps on the Amazon Appstore bring in almost four times as much revenue from in-app purchases as those on Google's own store, Google Play, a study has found.
The finding comes from mobile analytics firm Flurry, which in a new report looks at average revenue per user from a selection of the most popular free apps supported by in-app purchases available from the iOS App Store, Google Play and Amazon Appstore.
Setting the average iOS revenue per user to 100 per cent, Flurry found that the Amazon Appstore brought in 89 per cent of the Apple figure; Google Play, meanwhile, brought in just 23 per cent.
In a post on the company blog, VP of marketing Peter Farago pins Google's shortcomings on its relative lack of experience of operating a store, whether physical or digital. Apple, after all, has a worldwide portfolio of retail stores and operates iTunes; Amazon pioneered one-click shopping and is the world's largest online retailer.
Either way, it positions Amazon's Appstore as the preferred option for free-to-play games, in stark contrast to its perceived worth for paid apps. When the store launched last year, the International Game Developers Association was quick to warn developers off the service, because of the control over pricing the retailer insisted on retaining.
