But the fact remains that iOS users generate far more revenue overall than their Android counterparts. A person looking at market share and seeing 89% Android vs 11% iOS would be stupid to think that means the revenue split is also the same for both.
I don’t think you can blindly compare this in fairness. Maybe if you are talking games only, otherwise most people will have a blend of iOS and Android supported devices. The basis of the question still boils down to do you care about immediate revenue or do you care about growth? And what do you consider revenue?
In a past company I was at, we monetized on ads. The Android devices outnumber iOS/TvOS devices significantly. The order of revenue came from web > android / Roku > iOS > other. And if you watched Silicon Valley and how Jared bought a lot of users, guess where there are more users?
