Development of Financial Planner Application Software Based on Waterfall Model

Financial planning is necessary, especially for those who started to have savings. It can be achieved through thorough planning, organizing, directing, and controlling financial activities. To overcome these problems, we developed and designed the financial planner app. It can help all our users to control their money flow according to their budgets every month. In developing this project, Business Model Canvas is used to assess the key points and Waterfall Model is used to define the process. All requirements of the financial planner app are modeled using Use Case Diagram. To cope with the reduplication of coding for the app development, we used the Object-Oriented approach and made a Class Diagram to portray the relation between objects involved. Besides that, we also use Sequence Diagram to develop the flow process of our system. We also developed a prototype of the User Interface to give a picture of how the app's visuals. Finally, we used the Black Box Method for testing the “Financially” app and the results are given in the form of tables representing every page. We hope that this “Financially” app will be helpful and the impacts on our users align with the purpose of the creation of the app.
