A multiplatform mobile application for finance management with integration to banking institutions

The bachelor's thesis focuses on the development of a multiplatform mobile application for personal finance management with integration into banking institutions. The main objective is to create a practical tool that enables users to efficiently manage their finances, plan budgets, and analyze spending habits, thereby addressing the shortcomings of current applications on the market. As part of the thesis goal, the application also includes integration with banking interfaces for automated transaction loading and real-time balance synchronization, eliminating the need for users to manually input data. The thesis is based on an analysis of the current market state and the identification of key user needs. Based on these findings, a mobile application is designed as a solution for users who require comprehensive personal finance management, including expense tracking, budget planning, asset and debt management, with the possibility of automatic integration with bank accounts. The application is built on a client-server architecture using the MVVM design pattern. For development, the React Native technology was chosen, enabling multiplatform functionality on both Android and iOS devices, along with a robust backend built on Java Spring Boot. The main contribution of the thesis lies in a comprehensive multiplatform finance management application with advanced expense analysis, automatic banking integration, asset and debt management, robust security, and a personalized user interface that surpasses the limitations of current solutions. Additionally, it includes advanced analytical tools for financial flow visualization. Unique features also include support for asset and debt management, including the generation of accounting reports. The result of the thesis is a fully functional application that has been thoroughly tested and meets all proposed functional requirements. Among the most important implemented features are transaction management, multi-user mode, comprehensive security, and customizable user interface. The development followed the Agile methodology, ensuring flexibility and efficiency throughout the process. The thesis presents a concrete practical solution that combines user-friendliness with advanced features. Compared to existing applications on the market, it offers a more comprehensive approach to personal finance management while maintaining technological sustainability and potential for further development.
