Ever been on a trip where everyone keeps asking:

"Who paid for lunch?"
"How much do I owe?"
"Can someone calculate everything?"

I've been there more times than I can count.

Instead of passing around spreadsheets or scrolling through chat messages, I decided to build Pay Splitter.

💡 The Idea

Pay Splitter is designed to make shared expenses simple.

Whether you're:

✈️ Traveling with friends
🏠 Sharing rent with roommates
🍕 Splitting restaurant bills
🎉 Organizing events

It keeps track of every expense and calculates exactly who owes whom.

✨ Features
👥 Create trips and groups
💰 Add shared expenses
🧮 Smart settlement calculation
🌍 Multi-currency support
📶 Offline mode
📱 Direct UPI QR payments
🔗 Share trips instantly

I'd Love Your Feedback
