I just finished testing it. It is so so compared to other GPS app that can be found on this forum.
Yes it is free but that is pretty much you can say about it.
The reviews on GP are not the best also.....
But if you do not want to pay and then use this app......
Now you take "Osmand+" as an example is far better along with other gps apps that use OSM maps....
There will be other users that will list other gps app that are far better too.
