Really great app for snowmobile trails. The company also does an amazing job supporting snowmobile clubs.

It is a great thing, but needs more maps.

I downloaded and paid for an app and a few months later it’s gone!?

Better apps out there for much cheaper. This one does not have much for Wisconsin. Get the app maplets instead they do not charge for each map.

I did not have cell coverage along rt 24 and Trailtreker did a good job keeping me "on track". Few times the app was getting incorrect GPS positions. I emailed Trailtreker support and they fixed the issue quickly.
