Keep your iPhone contacts and Google Contacts up to date with two-way sync or a one-way direction you choose. REVIEW BEFORE YOU SYNC See proposed additions, updates and removals before your first sync. Compare individual contact fields and choose the iPhone account or list you want to sync. You can also preview later syncs and enable review before applying changes. SYNC YOUR WAY Choose two-way sync, iPhone to Google, or Google to iPhone. Control automatic sync and deletion syncing separately. Background timing is managed by iOS and depends on device settings, network access and system conditions. CONTACT SAFETY Local safety backups are saved before your first sync and before updates or removals. Export backups as vCard files for manual recovery in Contacts or Google Contacts. Importing a backup adds contacts; it does not automatically undo a sync. Deletion protection pauses unusually large removals for review. CLEAR STATUS See completed changes, inspect activity and check sync health. The app explains connection problems and Google update limits so you can decide what to do next. PRIVATE BY DESIGN Contact data moves directly between your device and your Google account. Our scheduling service does not receive your address book. Google sign-in tokens are stored in your device’s Keychain and sent only to Google. Optional background scheduling uses a push identifier and scheduling information; see our privacy policy for details. No contact limit, advertisements or subscriptions. The app interface is currently available in English. A read-only preview with sample data is available before connecting Google. Photos, groups and notes are not currently synced. This independent app is not affiliated with, endorsed by or sponsored by Google. Google, Google Contacts and Gmail are trademarks of Google LLC.
