This is a personal bookkeeping application centered on calculation. Users can input data, verify the amount, select a category and an account, and save each transaction. All calculated results are automatically rounded according to the precision requirements of the selected currency. When entering multiple transactions in succession, the app retains the previously selected category and account; it also restores any incomplete calculations and the cursor position, while preventing duplicate entries from accidental repeated taps. Each transaction record preserves both the original calculation process and its modification history, with any adjustments to the amount requiring explicit confirmation. The statistics page offers bar charts, pie charts, and line charts, and allows users to view transaction history filtered by date, category, or account. Frequently used entries can be saved with notes, pinned to the top, or reordered. Transfers between accounts automatically update the respective balances without being counted as income or expenditure. Additionally, users can export data to spreadsheets, create encrypted backups, and migrate their information using a recovery code.
