GPS

I am curious if anybody has used "Togo RV" and the services it provides for us RV'rs? If you have or are using the "Togo RV" are you satisfied with its ability to meet its intended purpose? Also,is there a fee for using the app? Is there one cost for annual usage or do you pay as you are using your RV i.e. not full timer. I read the terms of agreement for the "Togo RV" app and no where did I find a number figure for the cost. It sounds like it might be worthwile as it can give you road conditions on your direction of travel. Refueling locations and other amenities. I am interested to hear what others know about this app. Thanks
