A self-contained monthly budgeting planner: a bill list, a real calendar for daily spending, and a stamped Net Amount summary that updates as you type.
Add your bills and income once — due dates and amounts sync straight onto the calendar.
Mark anything recurring (monthly, weekly, biweekly, daily) and it carries forward automatically.
Everything saves locally in this browser as you go — nothing is uploaded anywhere.
Bill Categories
Bills are grouped automatically by icon. Utilities, Credit, and Other are built in and can't be changed; every other category can be renamed, reassigned a different icon, or removed.
Manage Accounts
Each account tracks a separate bank account independently. Switch between accounts using the tabs above the calendar.
