Great app!
This app is free, and it works. About the only drawback to this app is that it does require a good data connection. Itll work on edge, but will take some time and some luck to acquire a GPS signal. On 3G, this app orientates itself in about 5-15 seconds. Very accurate to my Garmin Nüvi and speedometer in my 4Runner (within 1-2 mph). More importantly, this app actually has come in handy. Used it clock a speed on a boat with no speedometer that a friend was looking at. Wonderful app, only complaint is to GPS acquisition time in Edge areas.
