Families & sub-groups
PWA on mobile & desktopGroup trips are never just “split equally”.
Someone pays by card, someone else pays cash, a couple shares one room, a guest joins halfway through the trip, and some costs should roll into the next one. Splitter is built for those real-world cases.
- Multiple people can pay the same expense
- Costs can split by exact amount, percentage, shares, or manually
- Families and sub-groups settle internally
- Guests can participate without creating accounts
- Historical FX stays fixed once an expense is entered
- Trip balances can roll into the next trip
Designed for real trip bookkeeping
Multiple payers
Record one expense with more than one payer, useful for mixed card and cash payments.
Five split modes
Split equally, by exact amount, by percentage, by weighted shares, or with manual adjustments.
Families and sub-groups
Group members into families or couples so internal balances stay clean automatically.
Multi-currency
Choose any currency per expense. Rates are snapshotted at entry so historical balances never drift.
Guests
Add people without accounts. They participate immediately and can claim their spot later.
Resolve balances
Log partial or full payments at any time during the trip.
Debt simplification
Reduce the group's debts to a minimal set of transfers.
Activity feed
Every change to a trip is traceable in a clear audit trail.
Receipt photos
Attach receipt images to expenses when the group needs context.
Trip rollover
When one trip ends, carry unsettled balances into the next trip as opening balances.
From first expense to final settlement
