Split Bill - Pay Friends

Paid the restaurant bill for your friends? Get paid back instantly with PromptPay QR codes!

Split Bill is the easiest way to divide restaurant costs among friends. Generate individual PromptPay QR codes for each person, so they can scan and pay you back instantly through their banking app. No more manual calculations or awkward "did you transfer yet?" conversations!

Key Features

[Automatic PromptPay QR Code Generation]
You pay the full restaurant bill, then the app creates individual QR codes for each friend. They simply open their Thai banking app (SCB, Kbank, Bangkok Bank, etc.), scan their unique code, and confirm. Amount, payee phone number, and reference are pre-filled automatically.

[Two Ways to Split Bills]
- Equal Split: Divide evenly among 2-10 people with automatic remainder distribution
- Itemized Split: Add each menu item individually and assign who ordered what. Perfect for restaurants where everyone ordered different dishes or drinks at different prices.

[Precise Satang-Based Calculations]
Our system calculates using satang (1 Baht = 100 satang) for maximum precision. No floating-point errors or rounding mistakes. The total always adds up perfectly.

[Multiple PromptPay Account Management]
Add multiple bank accounts and PromptPay phone numbers. Set your primary account for receiving payments. All QR codes automatically use your selected primary account.

[Payment Status Tracking]
Check who has paid and who hasn't. Mark people as paid when you receive their transfer. The app shows real-time payment progress (e.g., "2/5 paid").

[Complete Bill History]
Review past bills to see where you dined, with whom, and how much was spent. All bills are stored locally on your device for privacy.
