I made the mistake of making my game Android only (via libGDX). A lot of people are asking me for an iPhone/iPad version. Sigh. (Next time, I'll use Unity or Corona SDK.)
I've searched high and low, and cannot find much (relevant or recent -- beyond 2010) about market share of these two phones, globally.
Where can I find the relative market shares of these phones, globally, to some degree of accuracy? It doesn't have to be 100% accurate, as long as it remains recent (i.e. updated every few months). Ideally, this is something like Android's Platform Versions, albeit it tells me about different OSes.
I really want to know, because when I choose a development platform, it might matter (if I make the mistake of not using a cross-platform development tool).
