Together as one — your family's private home
Family expenses, split fairly and settled in one place.
A shared expense tracker for the household, a trip and the everyday — the running answer to who owes whom, without a spreadsheet.
Record what someone paid, split it equally or by share, and Onna keeps the running answer to who owes whom — across a trip, a household, or the everyday. Statements, budgets and settlements sit beside it, so nobody has to hold the arithmetic in their head.

Your first few minutes
- Start a trip or a quick split, and name who is in it.
- Add an expense; each person’s share is worked out, equally or by share.
- Settle through your own UPI app, and mark it done.
Onna never moves money. The UPI link opens your own bank app on your own device, and who has settled is what the people in the trip say.
