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.
"The rooms aren't the same size. Should electricity still be 50/50?"
Flatmates rarely split exactly in half: the bigger room pays a bit more, the person home all day takes more of the electricity. Futari can split by ratio, and once the ratio is set you can apply it to each expense without redoing the maths.
"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.
Open only to you two
Only your two accounts can open the ledger. Connections are encrypted over HTTPS, and sensitive details like a child's legal name or ID number are encrypted again before they're stored.
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.
Common questions
- What's a good app for splitting costs with a roommate?
- Futari is a shared ledger built for two people. It supports multiple split modes and real-time sync — so shared living costs are always visible to both without needing group chat reconciliation.
- How do we keep shared bills from turning into an argument?
- Log it when you pay and pick how it's split: rent by room ratio, shared supplies 50/50. If one of you fronts a cost, the running balance remembers it, so who pays next and how much is still owed is just a glance away.
- We're flatmates, not a couple. Can we still share a ledger?
- Yes. A ledger is for exactly two people, and you can invite your flatmate to join; you don't have to be partners. If one of you moves out and leaves the ledger, the shared history stays in a past chapter you can look back on.
