Abstract: An online match-making system, such as a smartphone or tablet application and supporting network, which is configured to promote contact between users when a mutual interest has been determined. Profiles are received from (and maintained in) a database. A user can view the different profiles, such as by viewing at least one picture associated with each profile. As the user views the different profiles or pictures, the user can indicate to the system whether or not he or she is interested in that person associated with the profile being viewed. The system keeps track of instances where a user indicates an interest in a given profile (i.e., interest in another person). When that other person logs onto the system, that other person is informed whether other users have indicated an interest, and is presented with profiles, wherein a proportion of the first plurality of profiles which are presented correspond to users who have previously indicated an interest in that person.
