About
ContactZapp syncs your contacts between Google, Microsoft, Apple and CardDAV, both ways.
Most professionals have a work account and a personal account. The two treat you as two different people, and your phone only knows the contacts in one of them. ContactZapp keeps the same contacts in both, and on your phone. Save a contact once, and it’s in every account.
