Personal Finance Tracking App

Overview

Billang is a gamified personal finance application designed to make expense tracking more engaging and approachable. Instead of relying on notebooks or spreadsheets, users can record daily transactions, organize their finances, monitor budgets, and visualize spending habits through an intuitive mobile experience.

By combining financial tracking with gamification, the application encourages users to build consistent money management habits through progress tracking, streaks, and achievements.

Problem

Managing personal finances manually is often repetitive and difficult to maintain. Recording every expense on paper or across multiple apps makes it challenging to review spending patterns, monitor savings goals, and understand where money goes over time.

Billang was created to provide a centralized and interactive solution that simplifies expense management while motivating users to stay financially disciplined.
