The app will update at regular intervals set by the user himself, meaning whether or not the currency is up to date will depend entirely on the user. This means you can always have the exchange rates for more than 150 currencies up-to-date.
Of course, you can also use this feature without an Internet connection, meaning you can take the app anywhere and use the currency value that was current at last connection time.
Currency Convertor is an app to check exchange rates and easily do currency conversions. In addition, thanks to its simple interface, it only takes a few seconds to complete the task you want to do.
