Works

I wish I didn’t have to use this app - but I’m very glad that I have it and it works well. I use the Mac OS X and the iOS versions.

I use apple products, Google apps and Gmail for critical communication, and Groups of contacts to manage different teams and projects.

This is the only solution that I have found that maintains groups accurately across these two conflicting platforms.

As a bonus, granular control over wiping/restoring contacts from cloud or devices and duplicate merging are helpful when things that should “just work” end up “just not” working and then you’re left with “just garbage” where your contacts used to be.
