* Linkee and Link of The Caller
With the Caller, turn your monotonous contacts into a social networking tool. Human brain has an inconvenient feature of forgetting unnecessary information quickly. However, such feature helps us concentrate on more important information stored in limited memory space. Then, how can the brain find forgotten memories? It uses linked information called relationship. It is similar to a mind map application or a link in a web search engine.

Your contacts have diverse information waiting to be linked. Contacts related to your family, brothers, cousins, businesses, lovers, relatives, and so on, and there is additional information which can be used to link these contacts, such as Toni’s lover, Emily’s family, Rich’s friend, etc. Even an independent contact can be linked in this way. All these information is available around you. Toni’s lover may be Rick’s family or Allen’s colleague. A person listed in your contacts is spouse of your colleague but also a member of your social club or a relative of a friend. Can you remember all of these relationships?

Although the number of items in your contacts may be limited, but you can create significant relationship from these. That is, you are the center of all of these things. Any popular keyword matching system used in other similar applications shows all the items they can find, but the Caller is designed to enhance its usability by querying your contacts step-by-step to find the information based on pre-linked data.

You can link several contacts to augment the value as you want. You do not need to worry about people to whom you cannot think of any relationship. The Caller will assist you to find related contacts more easily after you find a specific person or information you remember. This is the unique Linkee and Link functionality of the Caller, for which more diverse functionalities can be added easily. This is a huge leap from a simple keyword searching of other contact management applications.
