Currency Watcher (formerly Currencies) is market leader in currency rates tracking and conversion. With 2.0 update it is even better than before and really beats other currency converters. Just rotate your device to landscape mode to see history.
You can find other apps too complicated, because they offer many buttons and currency rates. However, this app wants to give you all rates as quickly as possible. For this reason Currency Watcher disposes of two modes:
1) Overview mode
Default mode after launch. You will see overview off all rates
as in Exchange office so you don't have to enter any value for conversion.
2) Conversion mode
If you need to convert some specific value of money to other currency, just tap to display and enter the value on the custom designed keyboard. Value will be converted to all supported currency
Currency Watcher offers 34 currencies. Data is provided by European Central Bank once a day. App needs internet connection in order to download rates, but if you have no connection, it uses the last downloaded rates.
