What it is

Sinking Funds Tracker is an offline app for anyone budgeting for planned costs: car insurance, holiday gifts, car repairs, vacations, property tax, school costs, pet care and more. Add a fund with the amount needed, the next due date and how often it repeats: every year, every 6 months, every 3 months or one time. The app works out how much to set aside each month. Tap Fund this month to add each fund's monthly amount in one go. When the bill comes, tap Paid it: the cost comes out of the fund and the next due date moves ahead. You can also spend part of a fund early. The dashboard shows your total in funds, the monthly set-aside, bills due in the next 60 days and funds that are short. Every fund shows ready, saving or short. Reports show money put in and spent each month, spending by fund and the yearly cost of every fund. The app does not connect to your bank or move money. It is a planning tool, not financial advice. Your data is saved only in your browser.
