UNYK is a smart address book that allows users to keep all their contacts (Hotmail, Yahoo, Gmail, Outlook, etc.) in one place. It is automatically updated as soon as one of the user’s contacts changes his or her contact info on UNYK.com.
Contrary to social networking sites, only the user can see their own contacts. Accessible through the Web, the service gives users control and allows them to share their contact info quickly and automatically with the UNYK ID, assigned to every user.
