An occasion worth repeating
Every group has its thing.
Cairn keeps the plan, the people and the shared money together — year after year.

A few examples
And whatever brings your group together.
Big calendar dates, small personal traditions — and everything in between.
For the dates everyone knows
Oktoberfest, Lowlands, Zwarte Cross, 4Daagse, Amsterdam Dance Event and Rock Werchter all create the same practical puzzle: different arrival times, changing schedules, meetup points and shared costs. Cairn gives the group one calm place to keep those details together after the tickets are booked.
For the traditions only your group knows
The annual cabin weekend, a family reunion, a birthday trip or something your friends invented years ago deserves the same shared home base. Keep the itinerary, people and expenses together without turning a familiar tradition into an administrative job.
Example occasions only. Cairn is not affiliated with the event organizers named on this page.

HOW IT WORKS
From group-chat chaos to one shared plan
Create the trip
Name the occasion, set the dates, and Cairn builds the home for everything else.
Everyone joins
One link. The whole group lands on the same page — no accounts to chase.
Build the itinerary
Add events, mark who's in, attach costs. Splits follow attendance automatically.
Run Event Day
Rally Points, live statuses, and offline essentials when it matters most.
THE ITINERARY
A timeline everyone actually sees
No more scrolling the group chat for the address. Events, times, and meeting points live on one shared timeline — and everyone answers for themselves.
Attendance per event, not per trip. "I'm in" for the main stage, "out" for the sunrise hike — no guilt, no guessing.
The guide travels with the trip. Door codes, Wi-Fi, house rules — pinned where everyone can find them.
One announcement, not forty messages. Plan changes reach the whole group at once.
THE MONEY
You owe €36.50. That's it.
No spreadsheets, no guilt math. Expenses attach to events, splits follow who actually showed up, and everyone sees the same clear number — in plain words, never a cryptic balance.

EVENT DAY
When the crowd swallows your group
Set a Rally Point before you go in. One tap says "Arrived" or "En route" — and the essentials stay on your phone even when the venue kills the signal.
