I hear it frequently mentioned that Android has larger market share globally, and as such is a better target than just looking at iOS market share in the US.
Is this a fair statistic? Let's say you're just writing on the first version of your app. That is, it doesn't have the full i18n and l10n treatment yet. How do things compare if we still set our sights globally, but we only look at the English-speaking population?
My hypothesis is that it might be worthwhile at least when starting out to target iOS just because it has a larger market share in the population that you're likely to hit first. Ideally later when your app has proven itself, you'd expand to different regions, different platforms, etc., but I've only ever seen one side of this statistic.
