I really wish iOS and Android would implement coarse grain location. My weather app doesn't need to know where I am exactly, within a couple of miles is usually fine. The "find the nearest store" just needs to know within a few blocks. The problem with GPS level location is that if I'm at home, I'm nearly personally identified.

If I know the rough location of your work and the rough location of your home I can almost certainly identify you: https://crypto.stanford.edu/~pgolle/papers/commute.pdf

Don't quote me on this, but I believe iOS already has this.. But it's the developer that needs to say they'll use this type of location data - which of course they won't.

Android has had that distinction since version 1, actually.


Some apps do use coarse permission (which maps roughly to wifi/cell tower location).

Yes, but I can't say "sorry, you're only getting coarse location" to an app that wants precise location permission.
