The phone application allows people to literally connect via Bluetooth and gather contacts automatically behind the scenes, while you go about your normal activities. RendezBlu will exchange contacts based on the preferences you’ve specified on your phone.

Unlike other social networks which can build artificial links, RendezBlu only connects people who came in close proximity to you, within range of about 30 feet or 10 meters, and who also had the application running on their phone.

Your network will therefore only include people who were physically near you at the same place, at the same time, and who were also willing to meet other people. Since you shared that proximity, chances are you also share some common tastes or interests.

In contrast to other sites which leave you sorting through thousands of totally incompatible contacts, RendezBlu will allow you to build a network of exciting contacts with truly great meeting potential.
