Splitwise alternative that splits by ratio, not evenly — free, no sign-up
FAMI-KAN is a free, no-sign-up bill-splitting web app for families, roommates, and group trips who need fair splits, not just even ones. Set a custom ratio per person (adults pay 1 share, kids pay 0.5, infants free) and every expense splits accordingly — automatically. Also tracks a shared "deposit" wallet for pre-collected trip funds and calculates the minimum number of transfers to settle up. 100% free, unlimited, no ads, no account needed.
