Orbis is a Mobile & Web application that allows users to create a group and then check-in to real places around the digital map of their region and thus mark those places with the symbol of the group they belong to. Those checkin-ins create opaque circles containing the symbol of their group inside. Those symbols are clickable and therefore anyone can click on the circles around the map and open a page containing the description of the group that is present there. The circles also increase or decrease in size according to checkin acitvity. Orbis creates a city's geo-social map.
