Contacts Sync for Google Gmail allows you to quickly and easily sync your Gmail and Mac contacts so you can have access to your contacts wherever you go. This app stands out from the competition with its reliability, ease of use, speed, and with a true "2-way sync" that allows you to merge changes you've made to your Gmail and Mac contacts.
Also of significance, this app syncs contact groups with Google. For instance, you may have your Gmail contacts organized into groups such as "friends," "family," and "coworkers." After syncing, your Mac groups will match your Gmail groups.
With the customizability that this app provides, it can be used in a number of creative ways. For example, you can backup your Mac contacts to Gmail, you can sync iCloud contacts with Gmail, or you can perform syncs in one direction only (such as Gmail to Mac).
