People in this splitCurrency
Add at least two people to start logging expenses. The split needs at least a payer and someone to split with.
How the math works. Each expense is split equally among whoever was on the line for it (everyone by default, or a subset). Whoever paid is credited the full amount, each sharer is debited their share. Net balances roll up across all expenses, and the "who pays who" list runs a greedy settlement that always uses the fewest possible payments.

About Shared Expense Splitter

Split shared expenses across roommates, a couple, or a trip group. Multi-person, multi-expense ledger that computes balances and the minimum number of payments to settle up.

Different from a tip calculator: that's a one-bill split. This is an ongoing ledger — weeks of grocery runs, the Airbnb deposit, the Costco trip, gas on the way back. Each expense has a payer, an amount, and an optional subset of people it's split among (defaults to everyone).

Whoever paid is credited the full amount; each sharer is debited their share. Net balances roll up across all expenses, and the 'who pays who' list runs a greedy settlement that always uses the fewest possible payments. All on-device — no group account, no cloud sync. Most useful for 3-6 people; works for any size.
