Google Calendars not showing in iOS7


I had a reasonably frustrating time with this issue this morning, and it took me about 2 hours to finally solve. So here’s hoping the following might save you a few minutes…

Problem: Google Calendars (eg from Google Apps) no longer show in iOS7 Calendar apps. Also Contacts don’t sync with Google contacts.

Solution: You need to completely delete your Google account from your iPhone and re-add it, making sure you use an Application password (if you use Google 2-step verification).


My email, calendar, contacts, etc are all part of Google Apps. For years these have all working seamlessly on my iPhone and iPad as well as my Android devices – a Nexus 7 and and HTC One.

However for the past week or two my calendar hasn’t been syncing on my iPhone. And after a little testing it turns out my Contacts weren’t syncing either.

Googling this, it turns out to be a pretty common issue, but with a variety of scenarios. My scenario is a little cloudy though, but amounts to this:

  • I upgraded my iPhone 4S from iOS6 to iOS7 on 22 September.
  • I backed up my iPhone 4S on 04 October
  • I inherited an iPhone 5 on 04 October – it was running iOS7
  • I did a complete reset of the iPhone 5
  • I restored my iPhone 4S backup to the iPhone 5
  • I realised on 16 October that my iPhone 5 is not syncing my Google calendar
  • Summary: The iPhone 5 is running iOS7 with my backup restored to it

Why mention this timeline? Simply because given how long it took me to realise the issue, I’m not sure whether the issue is due to iOS7 itself, OR to a restore to iOS7. eg I don’t actually know if the Calendar was syncing back when I upgraded my 4S to iOS7.

Why did it take so long to realise? Well, I use the GMail app for all my mail, and that has worked fine. Whereas I don’t actually use the Calendar app that much.

2-step Verification a possible contributor?

One other important item to note: my Google account uses 2 step verification – which I think is likely quite relevant to the issue.

My suspicion is that restoring a backup to iOS7 somehow voids a previous Google application password for the Google account.

Deleting Your Account

I tried various things (people suggested turning off SSL, just deleting the calendars from Settings, using other calendar app, adding a new Google 2-step application password, etc), but in the end I solved the issue by completely removing my Google Account altogether and then re-adding it.

This might sound scary, but actually you won’t lose anything – it’ll all get re-synced down once you add the account again. Here’s the steps I went through (you can click to enlarge any images):

First, go into Settings, and then > Mail, Contacts, Calendars:


Here’s how it looks before you delete – that’s my Google account there:

Before I delete my account

Drill into the account. And click the big red ‘Delete Account’ button. You’ll get the scary confirmation screen. Click ‘Delete from My iPhone’. It’s OK, trust me.

See that big Delete Account button - that's the one you click This is the scary message you get - proceed

You may find that after deleting, Settings then bombs out. That’s fine. Go into Settings again. Here’s how it looks after deleting:

Yep, my account is now gone

Adding the Account back in again

Click the Add Account, and you’ll see this screen.

Choose ‘Google’. In days gone by, you probably chose ‘Exchange’ but you don’t need to do that anymore. Choose Google:

Choose the Google option

Start entering your details.

Start entering your Google App details

Here’s the really important part – if your account uses 2-step verification, you need to enter an Application password here. It’ll be a special once off 16 character password you get from your Google account.

You can get it from here:

then choose the 2 Step verification section (or click here:

You can see all your current application passwords  here:

Generate a new Application password:

Generate a new Application specific password

and then enter it into your iPhone new account setup:

Important - enter your 2-step verification Application password here It will be 16 characters long

Enter the password, and then set the description as you like:

Name it appropriately

Click Next, and the account will verify. You’ll see a confirmation screen with green ticks – but I forgot to take a screenshot of that.

Click Save and then you’ll arrive back at the main accounts list, and Ta-Da there’s your account added back in:

Ta Da - it's back

And your account will now show in Calendar again:

Yay - my Calendar is back

The default settings for Calendar syncing is 1 month I think – you can set this to be longer (Eg if you want to see all your calendar appointments from months ago.

Other Options

The reason that most of the calendar apps were affected is because they use the main Account settings from iPhone Settings.

However, you can also use a different app that has Google authentication built in (ie similar to how the GMail app does). One example of this app is Sunrise. So, even if after going through all of the above and you still can’t fix it, you could try installing Sunrise and using that instead. It’s actually a really nice Calendar app.


And finally, for no good reason, here’s Lamby:

It's Lamby!
