About this app

Room for today. Ready for tomorrow.

Sseulon sets aside planned expenses from your budget until next payday and shows your daily spending amount. Keep track of everyday spending from your own entries, without connecting bank accounts.

See what is left today
Set a budget period and your next payday. Sseulon divides the budget over the remaining dates, including today, and subtracts today’s ordinary spending. Before a period starts or after it ends, review its records and balance instead of a daily allocation.

Set planned expenses aside
Reserve money for upcoming expenses before dividing your daily budget. When an expense occurs, record its actual amount and date. Linked planned expenses are not deducted twice from today’s ordinary allowance. Recording one as paid updates your records; it does not make a payment or transfer money.

A quick entry, a clearer day
Enter an amount and date, then choose Food, Café, Transport, Shopping, Home or Other. Add a note when useful and review the period’s expense history. Use the calendar to see spending and planned items by date, and review weekly totals and category amounts.

Use your currency
Choose Korean won, US dollars, Japanese yen or euros. Each period uses one currency, with no exchange conversion. KRW and JPY use whole units; USD and EUR support two decimal places. Daily allocations round down to the smallest unit, and overspending remains visible as a negative balance.

Your records stay on your device
Enter and review budgets offline without signing up. Budget amounts, expenses and notes are not sent to the Company’s server or included in advertising requests. Export all records and settings as JSON and restore from a backup. After confirmation, restore replaces all current app data rather than merging records. Backups are plain text without a separate password.

Choose Korean or English and light, dark or device appearance. Banner ads are included, but viewing or tapping an ad is not required to use budgeting. Advertising and external services you select may use a network connection.

Sseulon calculates amounts from your entries. It is not a bank balance service or financial advice and does not provide bank or card connections, actual payments, transfers, lending or investments.
