BanBan Ledger - Couple Budget

Living together, made simpler.

BanBan Ledger is a shared expense tracker and bill-splitting tool designed for couples, partners, and two people building a life together.

Record meals, transportation, shopping, household expenses, travel, income, and shared costs in one synchronized ledger. Flexible splitting, settlement tracking, budgets, spending insights, savings goals, a shared calendar, and widgets make managing life together easier.

【A Shared Ledger for Two】

Create a shared ledger and connect with your partner using an invitation code.

Both partners can add and review transactions, keeping shared income and expenses organized in one place. You can also create private personal entries to manage shared and personal finances in the same app.

【Flexible Expense Splitting and Settlement】

Quickly record an expense or income with an amount, payer, tag, payment method, date, and optional note.

・Split expenses equally
・Set custom percentages or exact amounts
・Choose who paid
・Exclude payment methods from settlement
・Select entries to settle
・Review settlement history

Meals, household purchases, trips, subscriptions, reimbursements, and shared bills can all be recorded clearly.

【Budgets and Spending Insights】

Review daily transactions through the calendar and understand monthly income, expenses, balances, and category breakdowns through visual reports.

Set a monthly budget or create budgets for individual tags and payment methods. Transactions can be excluded from analysis while remaining safely stored in the ledger.

【Recurring Transactions and Savings Goals】

Create recurring income and expenses to reduce repetitive monthly entry.

When a selected date does not exist in a month, choose to use that month’s final day or skip the month.

Create savings goals and track progress toward trips, shared purchases, future plans, and other milestones.

【Shared Calendar and Anniversaries】

Manage plans, trips, birthdays, anniversaries, and important dates in a calendar shared between two people.

Events support single dates, date ranges, monthly and yearly recurrence, reminders, Taiwan public holidays, and lunar calendar dates.
