This is an application focused on managing records, providing a convenient and efficient user experience. You can quickly add each piece of data at any time without waiting; you can also accurately query historical records based on custom criteria and easily view detailed information. The statistics page uses a clear and intuitive data visualization approach, including two core charts: a bar chart displaying total expenditures by category, and a line chart showing daily expenditure trends. Both charts support filtering by day, month, and year, allowing you to understand expenditure changes at a glance. In addition, the application displays key data in real time, with total expenditures, daily expenditures, and the highest expenditure type always clearly visible, helping you accurately grasp your financial situation and easily manage expenditures.
