Simple instant calculator for converting currencies.
Android version of Euro Calculator (Eurokalkulaator) distributed by Estonian government to ease the transition to euro currency in Estonia.
This calculator could be used for other currencies as well, just change the exchange rate in settings for desired currency pair.
Helps a lot when you travel.
It does not require an internet access, neither does it download the latest rates.
You have to set up that manually and this is because when you travel you often do not have data access with roaming. And you really do not care about the currency rates changes since you already have exchanged some money. So you can set up exactly the rate you have used for exchange.
