01 / Context

Personal Finance Tracker is a responsive web application designed with simplicity and usability in mind. It offers a clean interface that works across different devices while storing data securely using the browser's Local Storage API.

02 / The Challenge

Users often find existing financial tools either too simplistic, lacking necessary insights, or overly complex. The goal was to build a secure, client-side only solution that encourages better budgeting habits without needing a backend.

"Managing personal finances should not require users to understand complex financial systems."
