Currency Calculator

From currency conversion to exchange records, keep the numbers clear. Currency Calculator helps you prepare for travel and manage everyday foreign-currency calculations. Follow your favorite currencies, record actual exchanges and compare the quotes you receive. 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. INTERFACE LANGUAGE The app supports English, Korean, Japanese, Simplified and Traditional Chinese, Indonesian, Vietnamese, Latin American Spanish and Brazilian Portuguese. It follows your device language, or you can choose a language in Settings. Several tools use the Korean won (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. EXCHANGE RECORDS AND AVERAGE RATES Record purchases and sales of foreign currency, KRW amounts and additional fees. View your remaining foreign-currency balance, its weighted average purchase rate and the average rate across all purchases. 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 Explore available historical reference rates on a chart.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. EXCHANGE QUOTE COMPARISON Enter the rates and fees you receive to compare two to five quotes. Compare the total KRW cost for a fixed foreign-currency amount, or the foreign currency you could receive for a fixed KRW budget. Quotes are entered manually; the app does not fetch bank quotes automatically or execute exchanges. 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.
