IIRC a quarter of all active smartphones are iPhones globally. I'm not in the US, lots and lots of iPhones in circulation here. Also, no Briar on nearly all of those Androids, so they're just as reachable as iPhones.

Only Eastern Europe. Western Europe (incl Germany) and the Nordics have between 30-60% iPhones. [0] Also Albania, for some reason.
That's also pretty much the browser distribution you get when looking at analytics data from various European countries, and it matches what I see people use here (Germany).
