Great GPS without using data

I have used this app several times and it is much better than the old Tom Tom GPS I used to use when traveling. I downloaded the maps of the states I was visiting and entered the locations I wanted to visit into "favorites" using wifi at home or the hotel. It routed and provide voice instructions very well with cellular data shut off on my iPhone. Love this app. The only problems were a couple of times in remote areas the road did not match the exact same course shown on the screen and battery use is heavy so it helps to plug into a charger if using in a vehicle.
