MoneyCalin - Budget & Schedule

MoneyCalin is an app that brings your calendar and budget together in one place.

Manage your schedule and spending on the same screen — so your daily plans and cash flow stay naturally connected. See a full month of events and expenses at a glance, and understand your spending patterns through intuitive statistics.

Works without any server or login — all your data is stored safely on your device only.

Calendar • View schedules and transactions together on a single calendar • Supports single, multi-day, recurring, and multi-date events • Manage checklists (sub-tasks) inside each event • Smooth month navigation with left/right swipe • Swipe to delete, with a top banner to undo

Budget • Quick income/expense entry with categories, payment methods, and linked assets • Automatic month-over-month change calculation • Custom monthly start date (based on your payday) • Multi-condition filters — transaction type, category, payment method, amount range • Recurring expense, income, and transfer rules

Assets • See net worth at a glance with a donut chart of your assets (cash, accounts, investments, liabilities) • Drill down into each asset and adjust balances manually — changes are reflected in your budget automatically

Made for Korean users • Dedicated category for gift money (weddings, funerals, etc.) with sent/received statistics • Yearly goal tracking • 5 color theme presets • Multiple font options • JSON backup & restore — export through the Files app to share via email or messaging apps • CSV transaction export (Excel-compatible)

Privacy • No data collection, no login required • All data stays on this device only • No ad SDKs, no analytics SDKs, no crash reporters • Uninstalling the app deletes all your data with it
