A clean and simple currency calculator that supports the conversion to/from the following frequently traded currencies:

- USD, EUR, JPY, GBP, AUD, CAD, CHF, CNY, HKD, NZD, SEK, KRW, SGD, NOK, MXN, INR, RUB, ZAR, TRY, BRL, TWD, DKK, PLN, THB, IDR, HUF, CZK, ILS, CLP, PHP, AED, COP, SAR, MYR, RON, LKR, VND.

It uses the latest available exchange rate for each currency and tries to use a previously retrieved exchange rate during bad network conditions (e.g., bad connectivity in public transportations, airplane mode etc.).
