FOR GROUPS THAT TRAVEL TOGETHER

The group trips Splitwise can't handle.

A shared kitty, subgroups within trips, and balances that carry over to next year. Built for the friend, scout leader, or treasurer who's always keeping the group's money in order.

Settled up

You've done this before.

Every year, the same dance.

Someone keeps the kitty (probably you)

Different people send different amounts. Some chip in extra “just in case.” Others pay exactly their share. Receipts pile up.

Splitwise hits the daily limit mid-trip

Free tier limits make it useless for a real trip. Pro is overkill for one weekend a year. So you switch back to a spreadsheet.

And next year, you start from zero

Splitwise forgets your balances. Tricount loses data after updates. The friend with the spreadsheet is exhausted.

There's a better way to do this.

WHAT MAKES KITTYBOOK DIFFERENT

Built around how groups actually work.

01 · The kitty

A real kitty, not just IOUs.

Everyone deposits into a shared pot. Different amounts are fine — some pay exactly their share, others chip in extra “just in case.” The app tracks who put in what, who has credit, who still needs to top up.

When the trip ends, you don't owe each other random amounts. You know exactly what each person paid in, what they spent, and what's left in the pot.

02 · Subgroups

Subgroups within your trip.

Half the group goes wine tasting. The other half goes hiking. Three of you order pizza, the rest cooked. In Splitwise, you'd manually check and uncheck names for every single expense.

In Kittybook, you create subgroups once — “wine night,” “hikers,” “pizza crew” — and reuse them anywhere. Costs go to the right people automatically.

  • Define groups once, reuse anywhere
  • Costs split across the right people
  • The feature Splitwise users have requested since 2013

03 · Carry-over

Balances that carry over.

When the trip closes, surplus doesn't vanish. It becomes each person's personal credit for next year — automatically. Raymond paid €25 extra last year? That's his starting balance this year.

For groups with a yearly tradition — ski trips, scout camps, summer houses, bachelor parties that became an annual thing — this is the difference between “starting over every time” and “an actual ongoing treasury.”

HOW IT WORKS

Three steps. Less than five minutes.

1

Create your group and event

Add the people, pick a date, name your trip. “Ski Trip 2027” or “Summer Camp 2026” — anything you want. Done in under a minute.

2

Track money as it moves

Deposits into the kitty. General costs split across everyone. Subgroup costs split across some. Personal expenses charged to one person. The app does the math, you don't.

3

Close out, carry forward

At the end of the trip, see exactly where every cent went. Pay everyone out, or let the surplus become next year's starting balance — your call.

WHY NOT JUST USE SPLITWISE?

Because Splitwise was built to split a dinner bill.

Not to run a group treasury. Here's how Kittybook compares to the alternatives.

WHO IT'S FOR

Built for groups that organize together. Year after year.

If you keep doing this with the same people — this is for you.

Annual ski trips

Same crew, same week, every year. Your balances should remember.

Scout & youth camps

Transparent treasury. Parents see where every cent went.

Vacation house collectives

Shared property, shared bills, individual extras. Stop arguing in August.

Bachelor parties

Pre-pay the Airbnb. Track who joined which activity. Split fair.

Sports clubs & teams

Away matches, equipment, end-of-season events. Your treasurer deserves better than Excel.

Friend group traditions

The annual weekend, the wine club, the supper club. Whatever you keep doing together.

Large family trips

Multiple generations, different budgets. Fairness without awkwardness.

Student associations

Praesidium kassa, weekends, special events. Real treasurer accountability.

WHY KITTYBOOK EXISTS

Built by the friend with the spreadsheet.

I run an annual weekend with a group of friends. For years, I tracked the money in Excel — partial payments, extra deposits, who owed what, what was left over for next year. Splitwise couldn't do half of it. Tricount lost track between trips.

So I built what I needed. Then a friend asked if she could use it for her scout group. Then someone else for their vacation house. Now it's here, for anyone who needs it.

If you're the one who keeps the group's money, this is for you.
