Group trips end with a spreadsheet nobody trusts: five people reconstructing who paid for dinner on day three. The fix is logging each shared cost when it happens — who paid, how much, split how — so the final settle is arithmetic, not archaeology.
Thirty seconds: payer, amount, split. The running total per person stays visible all trip, which also quietly caps the 'order three appetizers' drift.
One transfer per person after the trip, computed from the ledger. No mid-trip Venmo chains, no IOUs aging into resentment.
