1. A computer-implemented method performed by one or more data processing apparatuses, the method comprising:

  • detecting formation of a location-sharing group between two or more mobile devices, wherein the formation of the location-sharing group is dependent on receipt of a request to form the location-sharing group from a first one of the two or more mobile devices, and a specification from a user of the first one of the two or more mobile devices which selects each additional mobile device of the two or more mobile devices which is to participate in the location-sharing group from a subscriber list;

    identifying a geographic area corresponding to an outline which encompasses the current geographic locations of two or more mobile devices in the location-sharing group;

    tracking changes in the geographic area dependent on changes in the outline,by receiving global positioning system (GPS) coordinates from the respective two or more mobile devices in the location-sharing group, processing said GPS coordinates to identify the current geographic locations of the respective two or more mobile devices in the location-sharing group, and reshaping the outline in a manner that corresponds to changes represented by the received GPS coordinates; and

    periodically updating a map to correspond to the tracked changes in the geographic area, and transmitting the updated map via a wide area network (WAN) to each of the two or more mobile devices in the location-sharing group, for electronic display thereon as a moving map which depicts location of each of the two or more mobile devices in the location-sharing group.
