I use organic maps, but mostly for cycling and walking. Mind that organic maps only works with offline maps (afaik), so if you are in an area that you havent downloaded the map for yet, you will need to download the entire map. Pluspoint to that is that you arent reliant on reception if you have the map
There was actually a german ad about this quite some time ago: a grandma did this, then called her grandson “i think i just deleted the internet”.
How the ad continued? No clue.
What it was advertising? No clue.
