My wife and I work for a designated driver service in Phoenix, AZ. Most of our business is local, but on longer-distance rides, she follows me in a chase car. Losing each other in traffic, at stoplights, or in unfamiliar neighborhoods was a constant problem, but this app has changed that. Now I just activate the app, and she can track me as I drive, so there is no fear of losing her way. It is easy to set up and even easier to use.
The only things which keep it from being a 5-star app are the lack of ability to follow you as you move, and no provisions for getting directions or planning a route.
