categorization / tagging is the most important thing to me
I want to see all of the contacts with a certain tag/group. This seems easy enough with the native contacts “group” functionality.
When I’m in a specific contact, I want to see all of the tags associated with that contacts. It seems crazy that the native contacts app cannot do this (or I haven’t figured out how to do this), so I’m leaning towards BusyContacts
I’m happy with either iOS or Mac apps.
I have no need to send group emails/messages to these people.
I have about 1500 contacts that I’m trying to manage.
It uses the native contacts, and turns Mac/iOS groups into tags. You can view all the tags for a given contact within their card, and also build Smart Groups around tags and other filters. Everything syncs to Mac and iOS version.
I gave up on BusyContacts. I used it as a secondary app for complex searches and filters, even though I didn’t like looking at it on the reg. I quit it completely after it lost contacts/data a few times. YMMV.
