How to Share a Family Calendar Between Google, Outlook and Apple

It is one of the most common frustrations in modern family life: Mum uses Google Calendar on her Android phone. Dad has Outlook through work. The kids are on iPhones with Apple Calendar. Everyone has events, but nobody can see each other's schedules.

The result? Double-booked weekends, missed school pickups, and the dreaded "I thought you were taking them to soccer" text at 4pm on a Saturday.

If this sounds familiar, you are not alone. The problem is not that families are disorganised — it is that calendar apps were never designed to work across platforms.

Why sharing calendars across platforms is so hard

Each major calendar platform has its own sharing model, and they do not play nicely together:

• Google Calendar lets you share with other Google users via email. Non-Google users get a read-only ICS link that does not update reliably.
• Microsoft Outlook sharing works beautifully — as long as everyone is on the same Microsoft 365 tenant. Family members with personal accounts cannot easily share with those on work accounts.
• Apple Calendar (iCloud) shares within the Apple ecosystem via Family Sharing. But if even one family member has an Android phone, the whole system breaks down.

The core issue is that each platform treats calendars as walled gardens. Google talks to Google, Apple talks to Apple, and Outlook talks to Outlook. There is no built-in bridge between them.

The workarounds (and why they fall short)

Most families try one of these approaches:

1. Subscribe to ICS feeds

You can export a Google Calendar as an ICS link and subscribe to it from Outlook or Apple Calendar. The problem? These feeds only update every few hours (sometimes up to 24 hours), and they are read-only. You cannot edit events from the other side.

2. Use a shared Google Calendar

This works if everyone has a Google account, but it requires non-Google users to maintain an extra account just for the family calendar. Events also will not appear in their primary calendar app alongside their own events.

3. Use a separate family calendar app (like Cozi)

Apps like Cozi provide a shared family calendar, but they are a separate silo. You end up checking two calendar apps — your own plus the family one — and things inevitably fall through the cracks.

The better solution: automatic cross-platform syncing

What families actually need is a service that connects their existing calendars together — so events added to any calendar automatically appear on everyone else's, regardless of which app they use.

That is exactly what Calendar Circle does.

How Calendar Circle works for families

Calendar Circle sits in the middle of your family's calendars, connecting them all together. Here is how to get started:

Step 1: Create your circle

Sign up at calendarcircle.com.au and create a new circle for your family. Give it a name like "The Smith Family".

Step 2: Invite your family members

Send invitations via email. Each family member signs up with their own account — they do not need to change their calendar app or create any new accounts elsewhere.

Step 3: Connect calendars

Each person connects their preferred calendar using secure OAuth sign-in:

• Google Calendar — sign in with your Google account
• Microsoft Outlook — sign in with your Microsoft account (personal or work)
• Apple iCloud — connect using an app-specific password

Step 4: Events sync automatically

Once everyone is connected, Calendar Circle syncs events across all calendars in your circle. When Mum adds "Dentist - Tuesday 3pm" to her Google Calendar, it appears on Dad's Outlook and the kids' Apple Calendars within minutes.

No manual updates. No checking multiple apps. No missed appointments.

What makes this different from other approaches

• Everyone keeps their own calendar app. No one has to switch or learn something new.
• Two-way sync. Events flow in all directions, not just one way.
• Near real-time updates. Changes appear within minutes, not hours.
• Privacy controls. Share as much or as little as you want — busy/free only, or full event details.
• No calendar clutter. Shared events appear as a separate calendar layer that you can toggle on or off.

Affordable family pricing

Calendar Circle is designed for Australian families, with plans starting at just $3.50 AUD/month for couples and $7 AUD/month for families of up to four. Yearly plans are also available from $36/year. Every plan includes a 21-day free trial with no credit card required.

Compare that to CalendarBridge, which charges US$48/year (roughly A$75) for just two calendars — and does not include family sharing features.

Frequently asked questions

Do all family members need to sign up?

Yes, each person creates their own free account and connects their calendar. This ensures secure access — Calendar Circle never asks for your calendar password (Google and Microsoft use OAuth, Apple uses app-specific passwords).

Will it show my work events to my family?

You choose which calendar to share. If you have separate work and personal calendars, you can share just the personal one. You can also choose to share only your busy/free times without event details.

What if someone in my family does not have a smartphone?

Calendar Circle works with any calendar that supports Google, Microsoft 365, or Apple iCloud — including desktop apps like Outlook for Windows, Mac Calendar, and the Google Calendar web app.
