Finally order in thousands of addresses!

BusyContacts delivers on its promise as an address book manager. The list view is very handy for adding data and filters allow you to create address groups conveniently.
The programme is versatile and connects to the main CarDAV servers and clouds. Records can be hosted synchronously on different servers, making duplicates history.
If you need to work with a mass of addresses, this programme is highly recommended. For quick access, however, the GUI of the nomal address book is a bit more convenient.
