Budget Burndown is a personal finance app that borrows the idea of a "burndown chart" from Agile software development. You set a monthly budget, which is plotted as an expected spending rate. Your actual spending plots against it as the month goes on. If you keep the lines matched up, you stay on budget.
It's a uniquely simple and logical way to visually track your spending across multiple cards.
There are no ads, credit scores, annoying emails, or overly-complicated designs. It's completely automatic. There's dark mode. There's a home screen widget. You don't even need to create an account.
