Here's my story!</p> <h2> Why I Built This? </h2> <p>I was tired of using complicated finance apps. So I decided to build one myself! It took time but the result is something I'm really proud of.</p> <h2> What FinTrack Can Do? </h2> <ul> <li>Track Income and Expenses - Add transactions with categories</li> <li>Financial Analytics - Donut chart + Monthly bar chart </li> <li>Savings Goals - Set targets and track progress</li> <li>Monthly Budgets - Set limits per category, get alerts when exceeded</li> <li>Recurring Transactions - EMI, subscriptions, rent - all automated</li> <li>Biometric Lock - Fingerprint / Face ID security</li> <li>Export Data - Download as CSV</li> </ul> <h2> Tech Stack </h2> <p><strong>Web Version</strong></p> <ul> <li>HTML5, CSS3, Vanilla JavaScript</li> <li>LocalStorage for data persistence</li> <li>Canvas API for charts</li> </ul> <p><strong>Android Version</strong></p> <ul> <li>Kotlin + Jetpack Compose</li> <li>Room Database (SQLite)</li> <li>MVVM + Clean Architecture</li> <li>Hilt for Dependency Injection</li> <li>WorkManager for background tasks</li> <li>Biometric API</li> </ul> <h2> App Screens </h2> <p>The app has 7 screens:</p> <ol> <li>Home Dashboard</li> <li>Audit Ledger (Transactions)</li> <li>Financial Analytics</li> <li>Monthly Budgets</li> <li>Savings Goals</li> <li>Recurring Transactions</li> <li>Settings</li> </ol> <h2> Live Demo </h2> <p>Try it right now in your browser!</p> <p><strong><a href="https://idyllic-crostata-12b745.netlify.app" rel="noopener noreferrer">https://idyllic-crostata-12b745.netlify.app</a></strong></p> <h2> GitHub Repository </h2> <p><strong><a href="https://github.com/Tpal41/FinTrack-Andriod-project" rel="noopener noreferrer">https://github.com/Tpal41/FinTrack-Andriod-project</a></strong></p> <h2> What I Learned </h2> <p>Building FinTrack taught me a lot:</p> <ul> <li>How to structure a clean MVVM architecture</li> <li>Working with Room database and DAOs</li> <li>Jetpack Compose for modern Android UI</li> <li>Chart rendering with Canvas API</li> <li>LocalStorage for web apps</li> <li>Netlify deployment</li> </ul> <h2> Final Thoughts </h2> <p>If you're thinking about building your own app - just start! It doesn't have to be perfect. FinTrack started as a simple idea and turned into something I actually use daily.</p> <p>Drop a star on GitHub if you found it useful!</p> <p><strong>Thakurpal Rajput</strong><br><br> Email: <a href="mailto:thakurpalrajput45@gmail.com">thakurpalrajput45@gmail.com</a><br><br> GitHub: <a href="https://github.com/Tpal41" rel="noopener noreferrer">@Tpal41</a></p> javascript webdev beginners android
