Stonker allows users to create multiple profiles which they can use check into events or locations. Users can automatically see all attendees at that event/location and they can use the App to send a connection request to attendees they would like to communicate with. If a connection request is accepted, both users receive the others profile details including phone number. Their contact details are also saved into each other mobile phone address book. A history of all events attended along with all attendees present is saved in the App for use at or after the event which means users can review profiles and send and reply to connection requests after the event has finished. Users can see the number of mutual contacts and the event history of attendees before deciding whether to send or accept a connection request.
