Here is how to synchronize your Google Calendar with your iPhone Calendar:

  1. Open the Settings application on your device's home screen.
  2. Open "Mail, Contacts, Calendars".
  3. Tap "Add Account".


4. Select Microsoft Exchange. iOS 4.0+ allows multiple Exchange accounts. However, if you're on a device that doesn't let you add a second account, you could also use CalDAV to sync Google Calendar and IMAP to sync Gmail.

Enter Account Info.

5. In the "Email" field, enter your full Google account email address. If you use a address, you may see an "Unable to verify Certificate" warning when you proceed to the next step.

6. Leave the "Domain" field blank.

7. Enter your full Google account email address as the "Username".

8. Enter your Google account password as the "Password". (If you are a 2-step Verification User, please use an Application-Specific Password instead.)

9. Click 'Next' at the top of your screen. Choose 'Cancel' if the "Unable to Verify Certificate" pop-up appears.

10. When the new "Server" field appears, enter

11.Press 'Next' at the top of your screen again.

12. Select the Google Services (Mail, Calendar, and Contacts) you want to sync. To receive and respond to meeting requests on your device, both Mail and Calendar need to be turned on and new invitations need to be enabled in your Google Calendar Settings.

To enable new invitations, sign in to your Google Calendar using the web browser on your phone or computer. Go to Calendar Settings > Calendars and click on the Notifications for the calendar you want to sync. Under Email, check "New Invitations" (and any of the other "Invitation Settings" you want enabled), then click 'Save'.

13. Unless you want to delete all the existing contacts and calendars on your phone, select the Keep on my iPhone (or iPad or iPod touch) option when prompted. This will also allow you to keep syncing with your computer via iTunes.

If you want to sync only the "My Contacts Group", you must choose to "Delete Existing Contacts" during the Google Sync install when prompted. If you choose to keep existing contacts, it will sync the contents of all contacts group instead. If there are no contacts on your phone, the latter will happen -- the contents of your ll Contacts Group will be synced.


Synchronization will begin automatically if you have push enabled on your device. You can also open the Mail, Calendar, or Contacts App and wait a few seconds to start a Sync.
