Managing personal finances has become increasingly challenging in today’s digital economy where online payments, mobile banking, and electronic transactions occur frequently. Many individuals perform numerous financial transactions every day, yet they rarely maintain proper records of their income and expenses. As a result, it becomes difficult to understand spending patterns and maintain an effective budget. Although traditional methods such as notebooks or spreadsheets can be used for financial tracking, they often require continuous manual effort and are not convenient for everyday use.

Mobile technology offers an accessible and efficient solution for personal financial management. This paper presents the design and development of a Budget Manager Android Application that helps users monitor their income and expenses using a smartphone. The proposed application allows users to record financial transactions, categorize expenses, and view summarized reports that highlight spending patterns. The system also incorporates graphical representations such as charts to make financial information easier to interpret.

The application is designed with a layered architecture consisting of a user interface layer, application processing layer, and database layer. This structure ensures efficient data handling and smooth user interaction. By simplifying expense tracking and providing clear financial insights, the proposed system aims to improve financial awareness and support better budgeting decisions.
