Salary-cycle household budget — see how much you've spent and how much is left this month.
Monthly Budget is a household budgeting app built around your salary cycle rather than the calendar month. You set your payday, and the app shows a cycle card with how much money is left (or how far you are in the red) and how many days remain until your next paycheck. Expenses can be split into fixed and variable so the app can compute your available amount automatically, and a calendar view colors each day by income and spending. Everything is stored locally first, so it works fully offline; an optional serverless sync exchanges JSON files through a shared Google Drive folder you control — there is no Sia Makerlab server.
