How Calendar Circle keeps everyone in sync

Watch a single event flow from one person’s calendar — in any platform — out to the rest of the family.

Built for households running on different calendars

One person on Outlook for work, another on Google for personal life, the kids on iCloud through their iPhones — Calendar Circle bridges them all without forcing anyone to switch.

Families

Parents juggling work calendars, kids’ school events and weekend plans — finally see the whole week in one view.

Couples

Stop the “are you free Friday?” messages. See each other’s commitments without merging calendars.

Extended Family

Coordinate visits, holidays and shared responsibilities across grandparents, siblings and adult children — on whatever calendar they already use.

What makes Calendar Circle different

All three platforms

Google, Microsoft 365 and Apple iCloud in the same circle. Mix and match however your household actually works.

Never blocks availability

Other people’s events appear marked “free” on your calendar — visible, never reserving your time.

Colour-coded by member

Each person gets a colour. One glance and you know whose event it is — no extra tapping, no name labels needed.

Auto-sync every 10 minutes

New event added on Outlook? It shows up on the family’s Google and Apple calendars within minutes — automatically.

Secure by design

OAuth for Google and Microsoft — we never see your password. Tokens encrypted at rest. Your data is read-only.

One-click invitations

Send each member a link, they sign in with their own calendar account, done. No spreadsheets, no admin panels.
