Kontakter is an advanced address book for Windows, Mac, and Linux. You can create both local and remote database to store your contacts.
Once you have created an account, hit the + sign and start adding the account details. When done, hit the save icon and the contact will be added to the database(list). It’s that easy. The app looks like Windows 7 themed because of it’s transparent background.
Apart from the basic information of contacts, there is also a place to leave important notes about the contacts. This comes important if you have lots of contacts. Leaving a note can quickly remind us about the contact. There is an option to add custom field too, in case you think the given fields are not enough.
On the left sidebar you will find the following three options apart from Add, Edit, and Delete contacts – Sync Contacts with central database(provided by Kontakter’s server), Settings, and Print Contacts.
All contacts are stored in a SQLite Database. You can Import/Export contacts to/from the database. Both VCard(.vcf) and SQLite can be imported, while you can export to these formats too in addition to PDF.
Alternatively you can also try out iContacts. Both Kontakter and iContacts are good, but I have said this before and I will say it again, these contact managers will only go mainstream if they allow users to sync contacts with Google Contacts, iPhone, and more. Enjoy!
