This is a bookkeeping application designed to manage amounts with inherent uncertainty. It utilizes a system of lines and graduated scales to clearly distinguish between confirmed amounts, estimated impacts, and records awaiting verification. The app supports the logging of income, expenses, transfers, and refunds; for uncertain figures, it allows users to define upper and lower bounds, while also capturing details such as dates, accounts, categories, and supporting documentation. The home screen provides an overview of income, expenses, and potential balance ranges. The ledger view offers search, filtering, and receipt/document management. A dedicated "associations" section tracks shared totals, equivalencies, and balance-based constraints. The verification page allows users to preview the ripple effects of confirming specific amounts, while the statistics page visualizes the origins of funds through bar, line, area, donut, and waterfall charts. The application employs stable variables to link original expenses with subsequent refunds, propagating constraints with integer-level precision to calculate feasible ranges—all while avoiding redundant computations. With support for data backup, restoration, and spreadsheet import/export, the app helps users transform vague recollections into reliable, structured financial records.
