Claim:
1. A computer-implemented method comprising: receiving location information of a first cellular device associated with a first user, the location information comprising global positioning system (GPS) coordinates generated by the first cellular device which represent a geographic location of the first user, and an associated time stamp; receiving a request from the first user to identify locations of other specific users who are in a predetermined list of the first user and who are in proximity to the first user; identifying the other specific users who are in proximity to the first user, dependent on a comparison between the GPS coordinates of the first cellular device with GPS coordinates of second cellular devices associated with the respective other specific users and dependent on a determination that the respective other users are within a threshold distance from the geographic location of the first user; transmitting via a digital communication network an indication to the first cellular device, the indication identifying each of the other specific users who is in proximity to the first user, as determined from the identifying, as well as information representing age of the GPS coordinates of each respective one of the second cellular devices within such proximity; storing information representing the geographic location of the first user in association with a profile of the first user; and transmitting via a digital communication network a map to the first cellular device, the map to display location of each of the other specific users who is in proximity to the first user.
