After taking a GPS audio tour at Gettysburg, I was excited to try this app at Yorktown. However, it did not live up to my expectations. First, the app does not direct you to each stop and the map is very slow to update. The flags are not numbered on the app, so it’s difficult to navigate without a physical map. Second, the narration at each stop is extremely short and overall provides very little context to the siege. Outside research is recommended. Finally, the narration in general leaves much to be desired. The narrator fumbles over his words and it seems like no editing was done to redo or cover up the mistakes. There is very little inflection in his voice and sometimes he is hard to understand. He never prompts you to get out of your car and walk around, but I highly recommend it. You will miss almost everything in the first loop if you don’t get out and walk around. I still enjoyed the tour, but mostly because of the signs posted along the way providing important information.
