Flatshare, couple, club: one shared pool where everyone adds their expenses. The app works out who owes what — and you settle in one tap.
The moment you share costs with a group over time, money gets blurry — and a little awkward. Always the same three headaches:
Everyone starts motivated, then expenses get lost in the group chat. Three weeks later, nobody knows where the group stands.
The question everyone puts off because it's awkward. The accounts get tangled, and that's where little tensions between friends start.
There's always someone who pays for the group… and then chases their money for weeks, never daring to ask.
Every expense goes into the shared ledger. Balances recalculate in real time — nothing gets lost.
The app says who owes what, in black and white. No more debate, no more mental arithmetic at the restaurant.
The fewest transfers to bring everything back to zero. You settle, and you move on.
Everyone adds their expenses, the app keeps the ledger in real time — balances up to date, zero math, zero awkwardness.
Other apps settle a trip, a dinner — then end up forgotten. Flish is your long-term group life : the flatshare that keeps going, the club, the collective. All your shared pools in one place.
From setup to the last euro settled — no spreadsheet, no argument.
Pick the type (flatshare, couple, club…), invite by QR. Your people join without even creating an account.
Someone fronts the money? They add the purchase. The app splits it by shares — equal or weighted.
The app works out the fewest transfers. You see your balance big and clear, you settle, done.
Everyone sees the same ledger — balances, expenses, settlements. No grey areas.
A QR is all it takes to enter a pool. You create your account later, or never.
The treasurer can run it all alone: add participants with no access, enter expenses for them. Our real differentiator.
Flatshare, couple, club or informal collective: the same tools, a theme per pool.
From the flatshare to the informal collective — each pool carries its own theme, from everyday to lightly serious.
Rent, groceries, bills, internet. The household's shared pool, always up to date — without the shared spreadsheet nobody fills in.
Expenses for two, without counting every cent day to day. You balance up whenever you want.
Treasury, dues, expense claims. The rigor of a proper ledger, readable by every member.
Team, crew, unregistered group: a shared treasury, with no bank account and no paperwork.
Every movement logged, every balance traceable. My flishbook for my statement, the big one flishbook for the whole group — printable, verifiable, balanced to the cent.
The best money app is the one you barely open. Flish is the group's memory : it files the expenses, works out the shares, keeps everything in order. You jot it down in two seconds — and get back to what matters.
Everything is logged, dated, traced. You have nothing left to remember.
No more math, no more chasing, no more unspoken tension that kills the mood.
You always know, exactly, where you stand. Without thinking about it.
