Kontakter 0.2 for Mac can be downloaded from our website for free. The program belongs to Productivity Tools. This free Mac app was originally created by GIOWISYS Software UG.
From the developer:
Kontakter is easy-to-use yet powerful address book with advance search functionality and a very intuitive user interface. The powerful search bar can find everything, just by writing partial strings contained in any field of your contacts. With Kontakter you can store your contacts in a local database or synchronize them with a central database, so you can share all your contacts with other users. Kontakter is free and open source software.
