🚀 I Built a Bill Splitting App Using HTML, CSS & JavaScript

After spending time splitting travel and group expenses manually, I decided to build a simple solution.

So I created Pay Splitter.

✨ Features

• Create trips
• Add friends
• Record expenses
• Automatically calculate who owes whom
• Smart settlement to reduce unnecessary payments

🛠 Tech Stack

• HTML
• CSS
• Vanilla JavaScript
• Firebase Authentication
• Capacitor
• Android Studio

Challenges

Some interesting problems I solved while building it:

• Google Sign-In inside Android WebView
• Optimizing APK size
• Managing offline data
• Settlement calculation

What I Learned

Building a real project teaches much more than tutorials.

I learned about authentication, APK generation, deployment, debugging, and improving user experience.

I'd love to hear your feedback or suggestions for future features.

Happy coding! 🚀
