Well, I don't want to sound patronizing, but the world is so much bigger than your notion of "Western world" where every student with iPhone has computer.
This fictional person you describe also has access to the web and Anki on there.
Anki is not a very useful tool if you are not making or editing your own decks or a teacher is for you. This is an incredibly painful experience on mobile.
I would agree with you, but he doesn't seem to mind
This is simply not true.
