Basic Expense Tracker Application: This app serves as the initial assignment (Assignment 1) for the IDATA2503 - Mobile Applications course at NTNU. Provided below is the essential documentation needed for this task.
Overview of the Application: This app is centered around a single screen called "ExpenseScreen." This screen plays a crucial role in managing all the expense-related information and actions. It's essentially the go-to place for everything related to expenses; we like to call it the "Single Source of Truth."
On this screen, you'll find a list that you can scroll through, showing all your expenses. Additionally, there's a simple chart above the list that gives you a visual representation of how your expenses are distributed across different categories. This chart makes it easy to see where your money is going. So, in a nutshell, this screen helps you keep track of your expenses and see where your money is being spent.

We worked together by discussing the class diagrams and commenting eachothers code. We didnt really have any problems with the projects, so there wasnt much help we could give eachother.
