In-App Purchases for iOS games. It’s a bit of a sensitive topic really, not many people like them at all, and quite a few people hate them and the impact they have had on the iOS games market. But today I want to explore the reason for their prevalence and explain why it has become an important part of the market for developers. I also want to reframe the discussion from one of “In-App Purchases are a problem” to one where we consider how they are being used and what developers could do to improve their implementation.
