Dear Web Devs: iOS and Android are not the only 2 platforms. Stop assuming with your app ads that, if my phone isn't 1, then it's the other .
Seriously, though, on a lot of sites I visit, they'll pop up a large ad at the top of the page saying "download our free app" even though the app isn't available on my phone. It seems to be a binary test like "If Android, show Android ad; if not, show iOS ad" or the other way around. ‎- Mr. Noodle
