AA-split couples ledger
You agreed to split fairly. Now how do you keep it straight?
50/50, taking turns, splitting by category — whatever your system, Futari logs it and keeps the running balance. No mental accounting, no end-of-month arguments.
"We said we'd go AA, but we never know who owes what."
The hard part of AA isn't deciding the split, it's remembering. Log the payer and the split at the moment you pay and the balance builds up, so you can both see how far apart you are right now.
"We take turns paying, but the amounts are never equal."
Alternating who pays looks fair in practice, but the amounts diverge over time. Futari records every transaction and shows the real balance — so fairness is measured in numbers, not turns.
"Some costs are AA, others are covered by one of us — we need both."
Futari supports multiple split modes in the same ledger. One expense can be 50/50, another fully covered by one person — no need for separate lists.
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 the best app for an AA-split relationship?
- Futari is a shared ledger built for two people from day one. It supports 50/50, income-ratio, and one-person-covers modes — and calculates the balance automatically so you never have to do the mental maths.
- How do I log taking-turns payments in Futari?
- Log whoever paid as the payer and choose 50/50; do the same when it's the other person's turn. When the turns match but the amounts don't, the balance shows the gap, and a settlement clears it.
- Can we log AA dinners with friends too?
- Yes. Your own AA split lives in the main ledger; for a dinner with several people, open an outing and send the link to your group. Friends join without installing anything, and when it ends you get suggested transfers, at most one fewer than the number of people.
