I don’t think it’s just games. iOS users in general are more willing to pay for software than Android users and Android users are more willing to pay than web users.
This was my experience doing consulting/contracting for most of the 2010s. Clients would want both iOS and Android, and we’d release with full feature parity. In every instance the iOS apps brought in 2x-5x the revenue, even when our Android apps had more active users.
I’ve always wondered why that is. I’ve had both Android and iOS phones and I’ve spent far, far more on iOS apps. I don’t think I’ve ever paid for a web app. There’s something about the platforms themselves then encourage or discourage spending.
