If you're a developer making a free-to-play games and you're not sure which mobile platform to target first, you'll probably want to check out today's App Monetization and Engagement Report from the mobile analytics firm Swrve. Based on data gathered from millions of users across dozens of IAP-powered apps, it looks like there's some truth to the generally accepted bias out there: people with iPhones can bring you more money.

How much more? Developers are seeing 45% more revenue per user according to Swrve's report. They further claim that there are 32% more users being monetized on iOS than Android, and that paying users are spending 10% more on iOS too.
