BillSplitter: Share Costs

BillSplitter helps friends, families and coworkers track shared expenses and see exactly who owes whom — no spreadsheets, no mental arithmetic.

SPLIT THE WAY YOUR GROUP ACTUALLY SPLITS
• Evenly across everyone
• Exact amounts per person
• By percentage
• By shares (one person counts double, another counts once)
Totals always reconcile to the last cent: remainders are redistributed so the split amounts add up to exactly the bill amount.

DEBT SIMPLIFICATION
If An owes Binh and Binh owes Chi, the app suggests An pays Chi directly. Fewer payments for the same money. You can also view debts pair by pair, exactly as the bills recorded them.

PAY BY QR CODE
Add the accounts where you receive money: a Vietnamese bank, a Czech bank or Revolut. Whoever owes you taps "Pay" and sees a VietQR or Czech QR Platba code with the amount and payment note already filled in — just scan it with a banking app. For Revolut it links to your Revolut page. Debts in another currency are converted at the latest exchange rate, and reminders say exactly how much to pay and to whom. BillSplitter never holds or moves money: the transfer happens in your own banking app.

GUESTS — NOT EVERYONE NEEDS THE APP
Add someone to a bill with just a name. When they want to track their own share, send an email invitation: their bills, splits and settlements move to their real account and the balances stay identical.

MULTI-CURRENCY FOR TRIPS ABROAD
Each group has a base currency; bills entered in another currency are converted at the rate you set. Over 80 currencies, including zero-decimal ones such as Vietnamese dong, Japanese yen and Korean won.

SHARED FUND AND RECURRING EXPENSES
Everyone contributes to a group fund up front, then meals and rides are deducted from it. Fixed monthly costs like rent or internet are created automatically on the day you choose.

TRIP NOTES
Itinerary, places to eat, where to stay, spots to visit — kept inside the group and checked off when done.

CLEAR STATISTICS
Charts show how much the group spent on food, how much on transport, and who has fronted the most money.

WORKS OFFLINE
Add bills even where there is no signal. The app syncs when connectivity returns, without creating duplicates.

FIVE LANGUAGES
Vietnamese, English, German, Chinese and Czech.

FREE, NO ADS
No in-app purchases, no advertising, no selling your data. You can delete your account and all your data from inside the app.
