I strongly recommend

Very useful App, even if 3G or Wi-fi are disabled. Recently I were in South África and Mozambique, and I could make conversions from and to rand, meticals, US dollars and brasilian reais. Even when the rates arent updated, the App is useful, giving us idea of the prices. I strongly recommend this App.
