About this app

byosw is built for the times you spend money with other people — group trips, shared rent and utilities, dinners with friends, gifts for someone, family expenses. It tracks who paid, who owes whom, and settles with the fewest transfers.

【Sound familiar?】

• Eight friends took turns paying on a trip, and now nobody can untangle the currencies.
• Roommates split utilities, but the bill is different every month and someone always feels shortchanged.
• Dinner for six, but two skipped the appetizers and one didn't drink — splitting evenly isn't fair.
• A group gift where everyone chipped in different amounts.
• You spotted a friend a cab fare three months ago and forgot.

byosw handles all of these.

【How it fits real life】

• Travel: Create a "Tokyo Trip" group, log expenses as they happen. At the end, byosw tells you who should transfer what to whom — usually two or three transfers settle the whole trip.
• Roommates: Create an "Apartment" group, split utilities by your preferred ratio (room size, headcount, or usage), and clear it month-end with one tap.
• Dinners: Open the app at the table, enter amounts and pick who joined — people who didn't come don't pay. Shared appetizers and individual drinks both work cleanly.
• Reimbursements: The Friends tab aggregates debts across all your groups, so you see at a glance who owes you and who you owe.
• Multi-currency: Yen for souvenirs, TWD for the hotel, USD for the taxi — auto-converted to your preferred currency.

【Premium in other apps, free here】

Many bill-splitting apps hide useful features behind subscriptions — advanced split methods, currency conversion, group limits...

byosw includes them all, free:

• Four split methods: equal, exact, percentage, shares
• Live multi-currency conversion
• Smart settlement (minimum transfers to clear all debts)
• Real-time push notifications, activity history, friend system
• Three sign-in methods, three languages, light/dark themes

Settle the money, then go enjoy each other's company.
