Simple Discount Calculator

At the store, shopping online, or splitting a bill after dinner — settle the tricky math in a few taps with this fully offline calculator. No account, no network, no permissions required.

🏷️ Discount Calculator
Enter the original price and discount rate to instantly see the final price and how much you saved. Stack discounts (like "30% off plus an extra 10% coupon") and the app works out the real effective discount for you — flat coupon amounts are supported too.

⚖️ Unit Price Comparison
Enter the price and volume for Product A and Product B to compare the price per 100g (or 100ml, or per item) and see which one is actually cheaper. Use the 1+1 / 2+1 preset buttons to quickly apply bulk-deal quantities.

👥 Split Bill
Enter the total and the number of people to get the amount per person. Choose to round up, round to nearest, or round down, and see the leftover amount when it doesn't divide evenly.

📋 Copy Results
Copy any result straight to your clipboard as text to paste into notes or chats.

🌏 Korean / English support
Pick your preferred language right in Settings.

🔒 Privacy-friendly
No sign-up or login needed, and nothing you calculate is sent to a server.
