Smart Daily Expense Tracker Application Using Kotlin

Personal finance management plays a vital role in maintaining financial stability, yet many individuals fail to track

their income and expenses regularly. Existing expense tracking methods such as manual records and spreadsheets are

inefficient and error-prone. This paper presents the design and development of a mobile-based Expense Tracker Application

using Kotlin for Android devices. The proposed system allows users to add income and expenses, categorize transactions, view

transaction history, and calculate real-time balance using a local database. The application focuses on simplicity, offline

functionality, and efficient data storage. Testing results indicate that the system performs accurately and provides a smooth user

experience. The application aims to enhance financial awareness and assist users in effective budgeting and expense control.
