The point is that "app" means application. "What does an application cost?" - well, is it a CLI that prints the current time in the terminal? Or is it Microsoft Word?

You can get a fully functional well polished fart button app for both iOS and Android made for less than $4k, but I doubt you could make something like the Facebook app on even one platform for $400k.

Any iOS dev worth his/her salt could make a well-polished fart button app in under an hour and for less than $100.

But no iOS dev worth their salt is gonna' do that.
