Navigation Apps Should Have a “STFU” Feature

I think its the platform that should give that option to the user be it android, iOS or what have you. You cannot trust individual apps developers and marketers to actually mean "Turn Off Tracking" even though the label next to the button says exactly that.

On Android turning off GPS is right there in the drop down menu. On iOS they would prefer for you to always have it on and hence the option is buried deep in the system settings, which is not as easily accessible as it is in Android.

They do though? You can turn off the voice directions right from the map screen.

Unless he's asking for smart recognition for it to toggle back and forth depending on if music is playing or not, but as far as I can tell that's not what he intended.

I think all apps that track you should have a "Turn Off Tracking" button. My app did. One button and you no longer turned up in search results (that showed a users location).
