It’s mediocre at best
That cone is way too small and faint on the app when it is enabled. It comes standard in Apple Maps, so I do not see why it has to be so tiny. Another problem is the bouncing around.
You constantly bounce around on the map, so if you are trying to geolocation yourself to a point it will be completely off base. I think it tries to predict where you are, but I’m not certain. But since this is literally the only game in town, they aren’t going to change any of it
