Sync Google Calendar to iPhone & iPad

This guide walks you through adding your Google Calendar to the built-in Calendar app on your iPhone or iPad, so your events, reminders, and appointments appear automatically across all your devices. You’ll need your Google account credentials (email and password or app password) and a stable internet connection. No third-party apps are required.

What You’ll Need

An iPhone or iPad running iOS 15 or later (the steps are similar on older versions).
Your Google account email address and password. If you use two-factor authentication, have your phone ready to approve the sign-in.
An internet connection (Wi-Fi or cellular) to add the account initially.

Step-by-Step

Open the Settings app on your iPhone or iPad. It’s the gear icon on your home screen.
Scroll down and tap “Calendar” (or “Mail” > “Accounts” on older iOS versions). The exact path depends on your iOS version, but you’re looking for the Accounts section.
Tap “Accounts” (if you’re in Calendar) or “Add Account” if you’re in Mail. On iOS 15 and later, you’ll see “Accounts” at the top of the Calendar settings.
Tap “Add Account” (or the plus icon). A list of account types appears.
Tap “Google” from the list. This opens a Google sign-in page.
Enter your Google email address and tap “Next”. Then enter your password and tap “Next” again. If you have two-factor authentication enabled, you’ll be prompted to verify it (e.g., tap a prompt on your phone or enter a code).
Review the permissions screen and tap “Allow” to let the iPhone access your Google account data.
Choose what to sync. You’ll see toggles for Mail, Contacts, Calendars, and Notes. Make sure the “Calendars” toggle is ON (green). You can turn off the others if you only want calendar sync.
Tap “Save” (or “Done”) in the top right corner. Your Google Calendar will now start syncing.
Open the Calendar app to verify. Your Google events should appear, often within a few seconds. If you have multiple Google calendars (e.g., a work calendar and a personal one), they’ll all appear as separate calendars in the app.

Common Mistakes

Not toggling Calendars on during setup. If you leave it off, your calendar won’t sync. Go back to Settings > Calendar > Accounts > your Google account and turn it on.
Using the wrong account type. Some users tap “Other” and try to set up CalDAV manually. That’s more error-prone. Always choose “Google” for the simplest setup.
Forgetting to enable sync in the Calendar app’s default list. Even after adding the account, your Google calendars might be hidden. In the Calendar app, tap “Calendars” at the bottom, then make sure the checkmark next to your Google calendars is green.
Expecting two-way sync to be instant. Sync can take a few minutes, especially if you have many events. Pull down on the calendar list to force a refresh.

Tips

Set the default calendar so new events you create on your iPhone go to your Google calendar, not the local “iCloud” calendar. Go to Settings > Calendar > Default Calendar and pick your Google account.
Use the Google Calendar app if you need more features like color-coding, event attachments, or the “Find a time” scheduling tool. The built-in Calendar app is fine for basic viewing and creating, but the Google app is more powerful.
If you have multiple Google accounts, repeat the steps for each one. They’ll all appear in the Calendar app under separate calendars.
To remove a Google calendar later, go to Settings > Calendar > Accounts > your Google account and toggle off Calendars, or delete the account entirely.

Troubleshooting

Calendar not syncing at all: First, check your internet connection. Then go to Settings > Calendar > Accounts > your Google account and tap “Sync” (or “Fetch New Data”) and set it to “Push” if available, or “Every 15 Minutes” if not. Also, try turning the Calendars toggle off and back on.
Events appear but don’t update: Pull down on the calendar list in the Calendar app to force a refresh. If that doesn’t work, restart your iPhone (hold the power button and volume up, then slide to power off).
Sign-in fails: Make sure you’re entering the correct Google password. If you use two-factor authentication, you may need to generate an “App Password” in your Google account security settings and use that instead of your regular password.
Duplicate events: This usually happens if you’ve previously synced via a different method (e.g., a CalDAV account). Remove the old account in Settings > Calendar > Accounts, then add the Google account fresh.
Only some calendars show up: In the Calendar app, tap “Calendars” at the bottom. If your Google calendars are grayed out, tap the info icon next to them and make sure “Show in Calendar” is enabled.

Frequently Asked Questions

Is it possible to sync only specific Google calendars? Yes. After adding your Google account, open the Calendar app, tap “Calendars” at the bottom, and you’ll see a list of all your Google calendars. Tap the info (i) icon next to any calendar and toggle off “Show in Calendar” to hide it. It will still sync in the background, but won’t display.
Will my Google Calendar events sync back to Google if I create them on my iPhone? Yes, as long as you create them in a Google calendar (not the local iCloud calendar). When you create a new event, tap the “Calendar” field and choose your Google calendar. It will sync back to Google within a few seconds.
Does this work with a Google Workspace (business) account? Yes, the steps are identical. Just sign in with your work email and password. If your organization requires special security, you might need to contact your IT admin for an app password.
Can I sync Google Calendar without using the Settings app? No, the only way to sync natively with the built-in Calendar app is through Settings > Calendar > Accounts. You could use the Google Calendar app instead, but that’s a separate app.
Why is my calendar not showing events even though it’s synced? Check if you have any filters active in the Calendar app (e.g., “Only shows events with attachments”). Also, make sure the calendar is not set to “Hidden” in the Calendars list. Finally, check that the event’s time zone is correctâ€”if the event is set to a different time zone, it might appear at an unexpected time.
Will syncing drain my battery faster? Push sync can use a bit more battery, but it’s usually negligible. If you’re concerned, set the fetch to “Manual” or “Every Hour” in Settings > Calendar > Accounts > Fetch New Data. You’ll still get updates, just less frequently.
