Fantastic App

I’ve only had the app for approximately 30 minutes and it is working like a champ - Prior to using the app I went to Gmail and cleaned up my contacts (merged duplicates, deleted some contacts) then I synced my iPhone (w/app) so it reflected the new contacts, then I used the Mac app - now whatever device I am on I have the most current contacts (set 2-way sync to auto). Worth the $3.99 it has saved me more than that in time.
