'''Geomium ''' is a location-based social networking website, and iPhone application. Unlike many other location-based services which focus on a single type of information, such as places or events, Geomium combines places, events, deals and people all into a single application. It aggregates its information from sources such as Yelp, Qype and Eventful. The service launched to the public on September 29, 2010, focusing initially on London, UK, with more cities and mobile platforms are planned.
In addition to all of the aggregated local information Geomium provides real-time location updates, allowing users to see exactly where their friends are, rather than the last location they checked into. In addition to private member-to-member communication the site features "shouts", public location-tagged announcements and recommendations that other users can comment on.
Geomium doesn't offer "badges" or other game mechanic type rewards that are currently popular among location-based services. Instead it is aiming to be a useful application that is attractive to the mass consumer, and aims to "connect people with the people and places around them, creating a social awareness that does not currently exist".
