🚀 Overview

Budget Tracker – Money manager, expense tracker, budget with AdMob Ads is a complete Android application for
personal finance management—recording expenses/income, setting monthly budgets, and visualizing spending with charts.
Built from real-world experience helping small teams ship finance utilities, the flow mirrors what users expect: add a transaction → auto-categorize → track against budget → export or back up.
