IBKTmoy

IBKTmoy is a bookkeeping application focused on tracking personal income, expenses, and the resulting balances. It organizes content using a grid-based layout and a five-section navigation system, offering a clear, distinct style for each ledger page. Users can manually record income, expenses, refunds, and account transfers. An overview screen uses a waterfall chart to illustrate how the final balance is derived, while a dedicated balance page displays monthly bar charts alongside cumulative annual trends; for any categorized amount, users can drill down to view the original individual transactions. A comparison feature allows for side-by-side analysis of two different time periods—aligned by calendar day—detailing how specific income, expense, and refund entries contribute to the difference in the balance. Monthly reports store statistical parameters, calculation versions, transaction summaries, and personal notes, with support for reordering, document export, and the retention of historical versions. Categories, accounts, themes, and encrypted backups are all managed locally. All amounts are calculated in whole-unit subunits (e.g., cents), and account transfers are excluded from the balance, ensuring consistency between daily record-keeping and periodic financial reviews.
