With Contacts Sync, you can quickly & easily sync your Google or Outlook contacts with iPhone, giving you access to your contacts wherever you go. This app distinguishes itself with its reliability, ease of use, speed, and with a true “2-way sync” that merges changes made to either account. This is the #1 app for syncing contacts both in terms of downloads & reviews.

Also of significance, this app syncs your Google labels or Outlook categories with iPhone. For instance, you may have organized your Google contacts into groups such as “friends,” “family,” and “coworkers.” After syncing, your iPhone and Google groups will match. Once your groups are synced, you can easily send group emails from your iPhone.

New for 2022, the app is now capable of syncing your Outlook contacts with one of your iPhone accounts, such as iCloud. Your Outlook contacts can belong to a personal account, such as Outlook.com, or a business account, such as Office 365.

New for 2021, the app is now capable of syncing 2 Google accounts with each other, so you can share the same contacts between a personal Google account and a work Google account, for example!
