Shared living expenses
You share a flat. How do you keep the bills fair?
Rent, electricity, internet, groceries — shared living costs are small individually but add up fast. Futari puts both of your records in one place so neither person has to keep mental track.
"Did I already pay the electricity bill this month?"
Fixed shared costs are easy to lose track of because they feel routine. Futari logs each payment as it happens — you'll always know what's been covered and what hasn't.
"Should we split 50/50 or by income?"
There's no single right answer. Futari supports 50/50, income-ratio splits, and one-person-covers-it modes. Set it once and the maths takes care of itself.
"One of us fronts most things and it's hard to keep count."
Futari's running balance always shows who's put in more. No need to ask, no need to keep track in your head.
How Futari helps
Flexible split modes
50/50, by income ratio, or one person covers it all — pick a mode and Futari handles the math automatically.
Real-time sync
One person records something and the other sees it instantly. The ledger is the conversation.
End-to-end encryption
Your ledger is visible only to the two of you. The server never decrypts what you record.
Chapter-based history
Moving in, getting married, new job, new home — each life chapter becomes a new ledger chapter. The past is always there to look back on.
