Thread: Best GPS mobile phone map apps

NZTopo50 user here too.
The aerial view isn't flash but I think if you zoom in full at home, then it caches some of that data.
Does everything I need. If you check out some of the howto information https://nztopo50.sqrl.net/ then it's pretty handy for stuff like uploading routes etc.
Still amazes me just how good the gps receiver on a phone is compared to dedicated gps units. Well, that's my experience so far.
