Split Instant

Split Instant makes splitting bills with friends, family, and groups fast and effortless — no sign-up, no accounts, and no internet connection required. Whether it's a trip, a dinner, rent, or any shared expense, Split Instant helps you track who paid what and instantly calculates exactly who owes whom — with the fewest possible transactions. KEY FEATURES Create Events Set up an event for any occasion — a trip, dinner, party, or shared household expense — and add the people involved in seconds. Individual or Family Splits Split costs person-by-person, or group people into families/households and split by family unit instead. Add Expenses Your Way Log expenses with flexible splitting — equal shares, custom amounts, or by who actually participated in each expense. Instant Settlement Calculation Split Instant automatically works out the simplest set of payments needed to settle everyone up — no manual math, no spreadsheets. Track Who's Paid Mark settlements as paid as people pay each other back, so you always know what's still outstanding. Reusable Members, Groups & Families Save friends, groups, and families once and reuse them across every new event — no retyping names every time. Multiple Currencies Choose your preferred currency for accurate, clearly formatted totals. Share & Export Share a settlement summary directly to WhatsApp, or export a clean PDF of the full event breakdown to keep or send along. 100% Private, Fully Offline Split Instant works entirely on your device. There's no account, no login, and no server — your events, expenses, and personal data are never uploaded anywhere. Uninstalling the app removes all your data, so we recommend exporting a PDF before you do. WHO IT'S FOR Split Instant is built for roommates, travel groups, couples, families, and friend groups who want a fast, no-friction way to split shared costs without creating accounts or navigating a complicated app. Simple. Private. Instant.
