It has a super clean UI with the most robust field options of any contacts manager I've used. It is far more powerful than Google, Outlook, or iCloud Contacts. It seems to sync pretty quickly with both Google and iCloud, but you can always manually sync it.
I love that it integrates with BusyCal (another fantastic sister software).
It has some unique things like social network integration but I do not utilize that very often. Review collected by and hosted on G2.com.
The only downside is it may not be an approved App / service for work (not the fault of BusyContacts). I use this on my home computer but am unable to put it on my work device, so I'm forced to manage those contacts separately, which is frustrating.
Lastly, I have a license via Setapp, which makes it more affordable than buying it as a stand-alone app, which is kind of expensive, in my opinion.
The downside to adding more fields and info is that it doesn't push back everything to the main source (Google Contacts). So if you want to see all the details you've added, you would have to always view it in BusyContacts. Review collected by and hosted on G2.com.
