KBS CE

KBS CE is an expense-tracking application centered on a weekly discretionary budget, presenting financial data through a clear, dashboard-style interface. The app features five distinct sections: "This Week," "Add Entry," "Transactions," "Weekly Report," and "Settings." It allows users to set and save a unique budget for each week, log expenses, income, and refunds, while automatically calculating net spending, remaining budget, and any overage in real time. Users can gain insights into their spending patterns through seven-day bar charts, categorical donut charts, and cumulative line graphs, with the ability to review historical weekly records at any time. Transaction entries can be searched, edited, deleted, or adjusted by date, and users have the flexibility to decide whether specific income items should increase their available budget. Additionally, the app supports data import and export, device authentication (security lock), and offline functionality—ensuring that weekly budgeting remains transparent and manageable, while balancing ease of daily use with the privacy of personal financial data.
