Computer software, including internet web page based code, and methods of applications are used with a mobile device tracking system. A locatable mobile communications device is tracked by a contact initiating website in conjunction with a user's desired contact profile. A user signs up or joins as a registered member and inputs the user's mobile communications device tracking information, such as Global Positioning System (GPS) receiver information. The main service website cross checks the user's input parameters against the parameters input by all other main service website members to identify a satisfactory match and notify the matched members to initiate a personal contact or meeting.
