Not bad

The information is great if you are following along with a cellular reception plan but is very difficult to use if you have no reception as most tourists do not and if the gps doesnt work on your device the app Is useless as it has no mile markers on the map supplied
Only a continuous reminder of what highway you are on, include mile markers in future updates and lower the price for this atrocity until then
