BCSIDelux vs BTGCIV

BCSIDelux is an application designed to analyze how personal fund allocation shifts across different life stages. Its home screen connects these stages via a blue timeline and a horizontal expenditure structure chart, helping users grasp the changing priorities of fund allocation at each turning point. The analysis employs a standardized classification system to compare metrics such as daily averages, fixed expenses, and category proportions; it visualizes structural evolution using Shannon entropy, expenditure concentration, Jensen-Shannon distance matrices, and percentage point differences. A structural simulation feature allows users to adjust category amounts or ratios, previewing the resulting allocation against both fixed and new total expenditure levels. Refunds and net negative expenditures are handled separately to prevent skewed distribution data. Data is stored locally on the device, with support for transaction editing, category tracking, and file import/export, all complemented by fine-lined charts and text-based index navigation. These metrics characterize the financial structure, enabling users to track financial changes and gain insight into each life stage.

BTGCIV is an application designed for managing income and expenses using natural language. It features a soft, grid-based card interface organized into four sections: Input, Verification, Ledger, and Statistics. Users can enter daily transactions in plain English; the app processes this text locally on the device to generate draft records for confirmation. By leveraging field-specific rules, an on-device classification model, and a personalized dictionary, the app identifies amounts, dates, categories, and accounts—while also handling complex scenarios such as shared expenses, transfers, refunds, discounts, and outstanding payments. Users can tap on any field to view the original source text, and manual confirmation is required whenever the app encounters ambiguity. Drafts retain the date and time zone from the moment of entry, ensuring that the intended meaning remains consistent even if the app is accessed on a different day. Once confirmed, records are saved as discrete transactions, preventing duplicate entries. The Ledger section supports manual entry, editing, deletion, account management, and the viewing of transaction receipts. The Statistics section visualizes income/expense structures and balance trends through bar charts, pie charts, and line graphs, with options to export ledger data and archives.
