About

Sync Contacts for Google

Features
Read full description

Keep your iPhone contacts and Google (Gmail) contacts perfectly in sync — automatically, in both directions. If you use both an iPhone and a Google account, your contacts get split into two lists that never quite match. A name you save on your phone never reaches Gmail. A number you fix in Google never shows up on your iPhone. Sync Contacts for Google fixes that for good: one contact list, always up to date on both sides. WHY PEOPLE SWITCH • No account limits — sync your whole address book, not a capped preview • Two-way sync — add or edit a contact anywhere and it appears on both sides • Runs in the background — sync happens automatically, and instantly whenever you open the app • Private by design — your contacts go straight from your phone to your own Google account. We never see them, store them, or sell them. BUILT SO YOU NEVER LOSE A CONTACT • See exactly what will happen before your first sync — nothing changes until you approve it • Automatic backups before every sync, with one-tap restore • Deletion guard pauses any sync that would remove a large number of contacts, so an accident can't wipe your address book • Smart duplicate detection merges the same person on both sides instead of creating copies PERFECT FOR • Anyone who lives in Gmail or Google Workspace but uses an iPhone • Setting up a new iPhone and wanting all your Google contacts on it right away • Keeping iCloud and Google contact lists as one merged, always-current list • Cleaning up and de-duplicating a messy contact list HOW IT WORKS 1. Sign in with Google (that is the only account you need) 2. Choose two-way, iPhone → Google, or Google → iPhone 3. Review the preview and tap Start — that's it SIMPLE, HONEST SYNC Contacts move directly between your phone and your Google account over a secure connection. There is no middle server holding your data. Background sync depends on iOS, so it typically runs several times an hour to a few times a day — and always the moment you open the app. Google, Google Contacts, and Gmail are trademarks of Google LLC. This app is an independent utility and is not affiliated with, endorsed, or sponsored by Google.
