Sumzy — Split Expenses

Who owes whom, and how much — per currency. Sumzy is a clean, fast way to split shared expenses with friends, roommates, couples, and trips. ADD IN SECONDS Log an expense in four taps. Equal, exact, percentage, or share-based splits — the amount always adds up to the cent, never a rounding penny lost. MULTI-CURRENCY, DONE RIGHT Run a trip in BRL, USD, and EUR at the same time. Balances, debt simplification, and settle-up are always per currency — Sumzy never mixes or converts them, and never shows a fake "grand total". SETTLE UP See exactly who to pay, in each currency, with the fewest transfers. Record cash or manual payments and watch the balance zero out. WORKS OFFLINE Everything is instant. Add expenses on a plane or in a dead zone — they sync automatically when you are back online, exactly once. IN YOUR LANGUAGE English, Portuguese, Spanish, French, German, Italian, Japanese and Chinese from day one. Real localization, not an afterthought.
