CashFlowMate: A Cross-Platform Mobile Application for Personal Financial Management

Abstract

Personal financial recording remains a challenge for most people because it is generally done manually or solely relying on memory. This condition causes transaction data to be easily lost, is difficult to monitor, and makes it difficult for users to accurately determine income and expenditure flows. This study aims to design and build a Flutter-based personal financial recording mobile application that can record income and expenses, manage transaction categories, display financial reports in graphical form, and provide monthly installment reminders through a local notification feature. The research method used is software engineering with a Waterfall development model that includes requirements analysis, system design, implementation, testing, and maintenance. Data collection techniques were carried out through literature studies and observations of the running system, as well as system testing using black box testing and white box testing. The results of the study indicate that the application was successfully developed and all main features can function properly according to the system design, including the transaction recording process, financial report visualization, transaction history, and automatic installment reminders.
