SingleSquare is a Foursquare iPhone application designed to help single people find and communicate with other singles currently around them. SingleSquare allows users to post "Single's Sightings" at places they are checked in to. Users can post themselves as being single, post other singles they see or post groups of singles to the sighting's list. These sightings are then compiled so that users can see a list of single sightings around their particular location so they don't need to waste time going out in search of singles to no avail. Users also have the ability to send direct messages to other Foursquare and SingleSquare users to gauge interest levels.
