iOS uptake is crazy high: 98% of the market has iOS version that’s not much older than one year.
It’s unsurprising to learn that Android uptake is much, much lower. If there’s something Apple does extremely well, it’s getting people to update their systems. I seem to recall OSX uptake is at a similar level.
The blog post from Unity also notes how much more popular iOS is in the Western world and shows Android’s dominance in the East. Not surprising, but it shows just why Apple is targeting countries like China (even issuing apologies because of state-run media). The East is Apple’s route to world domination – in mobile operating system terms at least.
