The ledger for groups that share the costs
Why Flishbook
Every group that shares expenses eventually lives the same scene. Someone opens a spreadsheet, fills it in for two weeks, then forgets it. The others never open it at all. And a month later the same question keeps going around: "wait, how much do I owe you again?"
Meanwhile there's always the one person who fronts everything: the groceries, the deposit, the shared gift, the dinner. Without counting, because counting would feel awkward. Except that, in the end, the imbalance adds up — and usually in silence.
Flishbook exists so that moment never comes. You log an expense, the app works out who owes what to whom, and everyone sees where they stand. No spreadsheet to maintain, no mental arithmetic, no awkwardness. Just accounts that stay clear, all the time.
Where we stand
Plenty of free tools carry a hidden price: your data. We chose the opposite. Flishbook shows no ads, doesn't track you, and sells nothing to anyone. That's not a marketing line — it's the way the product is built.
So how do we keep the lights on? One shared pot is free for life, for up to ten participants — enough for the real life of a flatshare, a couple or a small collective. Those who want more pots or more participants move to flish+, a pay-what-you-want subscription: you decide yourself what it's worth to you.
We'd rather live off the people who like the tool enough to support it than monetise everyone's attention or history. It's slower, but it's honest — and it lets us look you in the eye.
For groups that last
Splitting the bill for one dinner is something plenty of apps can do. Flishbook is built for what comes after: groups that keep existing, month after month.
A flatshare with its recurring bills. A couple with a shared budget. An association that calls in dues, tracks its spending categories and closes its financial year. An informal collective with a small kitty to keep alive.
That calls for a real ledger: an audit journal that keeps a trace of everything, vaults to set money aside by purpose, categories with reports and CSV export, sign-off on large expenses by designated signatories, and a clean way to close a project. One treasurer can even run the whole thing alone, add participants without asking them to create an account, and record entries on their behalf. Everyone else joins with a QR-code scan, no password — a simple code by email is all it takes.
Who publishes Flishbook

Being based in Switzerland matters to us: it's a demanding framework for data protection, and it fits our refusal of advertising and tracking.
