Korhner Phonebook description
Phonebook is an easy to use contact manager

Phonebook was designed to be an easy, but at the same time, a very powerful
contact manager. You can create an unlimited number of contacts( the only
limit is the Ram) and even save them to separate files.

Then you can find info about people either with a fast and simple search, or even with a powerful search dialog. Another interesting feature is to check for people birthdays. You can even print your contacts if you want a hard copy of them!
