Google Latitude

Google Latitude is a location-aware mobile app developed by Google as a successor to its earlier SMS-based service Dodgeball. Latitude allows a mobile phone user to allow certain people to view their current location. Via their own Google Account, the user's cell phone location is mapped on Google Maps. The user can control the accuracy and details of what each of the other users can see — an exact location can be allowed, or it can be limited to identifying the city only. For privacy, it can also be turned off by the user, or a location can be manually entered. Users have to explicitly opt into Latitude, and may only see the location of those friends who have decided to share their location with them.

On July 10, 2013, Google announced plans to shut down Latitude.
