The app needs an internet connection to change currency. While using the app, we can update the exchange rates by pressing the update button. Easy to use, just enter the amount to be converted and set the exchange rates to be converted. Conversion is already running when you enter the amount! It also launches two conversions at a time. The main conversion is counted when the right-hand value is marked in yellow. To select the main conversion, just tap the value. The last conversions are achieved by dragging the screen to the right. On the settings screen, you can set the rate of the selected conversion to appear on the icon. The exchange rate occasionally requests an update on the icon. Show Badge is subscription-based. You can query a few conversions for a selected auction, the value of the exchange rate that can be retrospectively reached for 365 days. Retrieving Advances is subscription-based. You can query a few conversions for a selected date period, the value of the exchange rate that can be retrospectively reached for 365 days.
