1. A computer-implemented method of sharing position data between a first device associated with a first user and a second device associated with a second user, the position data including first position data indicating a first location associated with the first device and second position data indicating a second location associated with the second device, the computer-implemented method comprising:

  • receiving, from the first device, a first request to set up a relationship between the first and second users;

    transmitting a second request to the second device, the second request inviting the second user to accept the relationship;

    receiving a message from the second device indicating acceptance of the relationship;

    establishing the relationship responsive to the acceptance;

    receiving first position data from the first device and second position data from the second device, each in the form of GPS coordinates; and

    transmitting the first position data to the second device and the second position data to the first device;

    wherein the second user is one of a plurality individuals identified in a list, each of the individuals being associated with a corresponding mobile device;

    wherein the method further comprisesidentifying a geographic location based upon the GPS coordinates for each of the first and the second devices, andcausing the first device to display positions for a subset of the individuals who are in the list based upon the geographic location; and

    wherein the method further comprises causing one of the first and second devices to display to the first or second user an option to request voice communication with the other of the first or second users, and, responsive to selection by the first or second user of said option, initiating the voice communication over a cellular network.
