Korean Currency is a free Android application developed by irmavepdev that provides its users with foreign exchange rates based on Korean currency (KRW). With this app, you can quickly check the exchange rates of major countries and calculate exchange rates in detail view by touching anywhere on the screen.

The app displays the current currency and changes against yesterday, and it is based on Korean time (GMT-9). However, it does not report on Saturdays, Sundays, and Korean holidays. The app also features an exchange rate list, a calculator, a widget, and a notification system that alerts users when the exchange rate meets certain conditions. It is important to note that exchange rate information is not updated on weekends and holidays, and data usage settings are required to use widgets or notifications when using mobile data instead of WiFi.

Overall, Korean Currency is a convenient tool for anyone who needs to keep track of foreign exchange rates and wants to calculate exchange rates quickly and accurately.
