Currency Calculator

Compare costs before exchanging. Track your average rate afterwards.

Compare the quotes you receive, record your own exchanges and understand prices while travelling. Quotes, exchange records, card estimates, alerts and widgets use South Korean won (KRW) as their reference currency.

COMPARE EXCHANGE COSTS
Enter the rates and fees offered by banks or exchange counters to compare 2–5 quotes. See the total KRW cost for the same foreign-currency amount, or the amount you could receive for the same KRW budget. Quotes are entered manually; the app does not collect bank quotes or execute exchanges.

TRACK YOUR OWN AVERAGE RATE
Record foreign-currency purchases, sales, KRW amounts and separate fees. View your remaining balance, its weighted average purchase rate and the average rate across all purchases. These figures are calculated from the records you enter.

Read prices from photos
Photograph a price tag or choose an image from your gallery to read and convert a price. Select among multiple prices, edit the amount or currency, and view the recognized text. Photo recognition runs on your device.

36 INTERFACE LANGUAGE CHOICES
Choose from 36 language options, including English, Korean, Japanese, Chinese, Hindi, Arabic and French. Follow your device language or choose in Settings. Exchange records, quotes, alerts and widgets use KRW as their reference currency.

CURRENCY CONVERSION
Convert amounts across 48 currencies, including US dollars, Japanese yen and euros. Check the reference rate's date and source alongside your calculation.

FAVORITES AND RATE HISTORY
Keep frequently checked currencies in a dedicated watchlist. Explore available historical reference rates on a chart. Historical coverage varies by currency and provider.

TARGET RATE ALERTS
Set a KRW-based target and choose an at-or-above or at-or-below condition. The app checks rates periodically and can notify you when the observed rate meets your condition. Notification permission is required. Data update schedules, battery-saving settings and network conditions may delay checks and delivery. These are not real-time market-price alerts.

ANDROID HOME SCREEN WIDGET
View reference exchange rates for up to three selected currencies against KRW on your home screen. Check the reference date and update status, or refresh manually.

MORE CALCULATION TOOLS
Use a standard or scientific calculator, estimate overseas card-payment costs and calculate exchange-rate discounts. Light and dark themes are available.
