Track who paid, who owes, and the fewest payments to settle — across friends, groups, trips, and currencies. No spreadsheets, no awkward texts.
FairFold does the arithmetic so nobody has to keep a running tally in their head.
Enter what was spent and who was in on it. Split it evenly, by shares, by exact amounts, or by percentage — even across multiple payers.
Every net balance recomputes instantly and stays exact — per person, per currency. No stored number a bad sync could corrupt.
FairFold collapses the tangle of IOUs into the fewest possible payments. Pay, mark it done, and the group zeroes out.
Trips, roommates, dinners, and the friend who "forgot their wallet" again.
One trip, five currencies. Each amount stays whole in its own currency — conversions are shown, never baked in, so nothing rounds away.
Turn a web of who-owes-whom into the minimum number of payments. One tap, fewest transfers, everyone lands at zero.
Guest groups let people join by link — no account, no download. First-class from day one, not a stripped-down side door.
Add someone to the group by scanning a QR code across the table. No typing phone numbers, no waiting on an invite.
Add an expense on a plane or a basement bar. It's saved locally and syncs the moment you're back online — no lost entries.
See where the money actually went — by group, by person, over time — with charts that read clearly instead of just looking busy.
Splitting money between friends should never be "roughly right." Under the hood, FairFold treats every cent like it matters — because someone always notices when it doesn't.
Whole-cent accuracy. Money is stored as exact minor units, never a floating-point approximation. A split of €10 three ways always sums back to €10.00.
Balances are derived, not stored. Every balance is recomputed from an immutable ledger the server owns — no mutable number a stale device can overwrite.
Per-currency, always. A group can hold euros, yen, and dinars at once — each tracked in its own real precision, never collapsed into one fuzzy total.
