FinSense - Smart Expense Tracker

FinSense is a Progressive Web App (PWA) designed to look and feel like a premium mobile app. It features Smart SMS Parsing, Expense Trends, and Dark Mode.

How to Run Locally (Developer Mode)

You need two terminals open to run the full stack (Frontend + Backend).

1. Start the Backend (Server)

This manages the Database (MongoDB) and API.

cd backend
npx nodemon server.js

Port: 5000

2. Start the Frontend (UI)

This runs the React Interface.

cd frontend
npm run dev

Port: 5173

3. Open the App

• Go to: http://localhost:5173
• Mobile View: Right-click > Inspect > Toggle Device Toolbar (Ctrl+Shift+M) to see the mobile layout.

How to Share / "Send" the App

Since this is a PWA (Web App), you have two options:

Option A: The Web Way (Recommended for Hackathons)

You deploy the website to the internet. Users visit the link and click "Add to Home Screen".

1. Push code to GitHub.
2. Connect GitHub repo to Vercel or Render.
3. Share the URL (e.g., finsense.vercel.app).
4. Users install it instantly (No APK download needed).

Option B: The Native APK Way (Advanced)

To get a real .apk file that you can send via WhatsApp:

1. You must convert this project using Capacitor.
2. Requirement: You MUST have Android Studio installed on your PC to build the final file.
3. Commands:

   cd frontend
   npm install @capacitor/core @capacitor/cli @capacitor/android
   npx cap init
   npx cap add android
   npm run build
   npx cap sync
   npx cap open android

4. Then, inside Android Studio, you click "Build APK".
