Group trips, kept together.
The plan, the people, and the money — finally in one place.
Now onboarding early group organizers
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.
Plan and split
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 PLAN
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. Costs 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.
