Start a group calendar

£14.99 for the whole group.

You won’t have to chase anyone. We do the nudging.

Up to 24 friends, family or teammates each fill a few doors in secret. From 1 December you all open the same door every morning, see who made it and pile into the comments.

How it works for the organiser

  1. 1

    Name it

    “Our years at university”, “Team 2026”, or anything goes.

  2. 2

    Share one link

    People join with a first name. No accounts, no app.

  3. 3

    Hand out the doors

    Spread them evenly in one tap, or give the keen ones more.

  4. 4

    Sit back

    We nudge anyone who’s behind. Missed doors become a question for everyone.

  5. 5

    Open together

    From 1 December, one door a day, for everyone at once.

You won’t have to chase anyone

  • Friendly nudges.

    We remind people before their deadline and again on the day, so you never have to be the one who asks.

  • Rolling deadlines.

    Each door is due two days before it opens, so you can start before everyone’s done.

  • No empty doors.

    If a door’s missed, that day turns into a question for the whole group.

Not everyone’s techy? No app, no account. If they can open a WhatsApp link, they’re in.

Nobody has to guess who made it

Every door shows who’s behind it: name, face and colour. Then everyone can react and reply, so each day turns into a little conversation.

Our years at university

Door 7 is open.

    What you’d order if we were all at the pub tonight

Doing it with work?

It works brilliantly for teams. You get an emailed receipt you can put through expenses.

Share a door with the world (optional)

Any member can share their own door with a link. The whole calendar only goes public if everyone agrees.

Questions

What if someone doesn’t fill their doors?
We send them a few friendly nudges. If they still miss it, that day becomes a question for the whole group, so the door is never empty. Often it’s the liveliest day of the lot.
Does everyone need an app or an account?
No. It’s a link. People join with a first name and fill their doors on any phone or computer.
Can the organiser see what’s behind the doors?
No. Everyone only sees their own doors until they open, so the organiser gets surprised too.
We’re in different countries. Does that work?
Yes. The organiser picks one time zone and the door opens for everyone at the same moment, wherever you are.
Is it too late to start?
You can start until 20 December. Your calendar runs from that day to the 24th, at the same price, and we’ll tell you how many doors you’ll get before you pay.
Can strangers see our calendar?
Not unless you choose to share it. Each person decides whether their own door can be shared.
Can children join?
Group members need to be 13 or over. Children can appear in photos and videos, added by an adult.
