"Contacts Sync" is the best app for syncing Google contacts. You can download it at:
While "Contact Mover" can sync Google contacts, "Contacts Sync" is the better choice as it offers the following advantages:
- Using "Contacts Sync", your Google contact updates will appear on the web immediately at google.com. With "Contact Mover," there may be a delay, as "Contact Mover" depends on iOS to transfer changes to the web, and iOS sometimes stalls.
- Using "Contacts Sync," you can sync your contact groups so that they appear on your iPhone. "Contact Mover" does not have this capability.
- Using "Contacts Sync," you can sync a Google account even if it is not configured in your iPhone Settings > Passwords & Accounts.
