Futari — Shared Ledger

Futari is a shared ledger made for two people. Not a cold money tracker — a place where two people note down each day together, and see it together. Look back, and you'll remember how that stretch of life felt. Record together, see together ・One ledger for both of you — who paid and how it splits is always clear. ・Automatic splitting and settle-up, so no one has to do the math in their head. ・One person can start first; the other joins later. Turn the days into a spectrum ・Expenses, income, and recurring entries build up into your shared record. ・Monthly review: at the start of each month, last month becomes a note the two of you write to each other. ・Trip ledger: open a separate ledger when you travel; it folds back into the main one when you return. More than money ・Keepsakes: car, home, child, pet, plant, insurance — note down the things you care about together. ・Multi-currency: record in the local currency abroad; it converts back to your home currency automatically. Use it with peace of mind ・End-to-end encryption: sensitive fields are encrypted with AES-256-GCM before they're stored — no plaintext in the database. ・Data is stored in Tokyo, Japan, protected by encrypted transport and access control. ・You can delete your account anytime from Settings. ・Free to use, on iOS / Android / Web. Two people, one ledger. Keep the days as light you can look back on.
