Currency Master

The most practical currency converter on the iPhone, with a builtin simple calculator and trend charts.

Designed to be used on the go, while abroad. Great care is taken not to connect to the internet unless you explicitly allow it to (to avoid any unnecessary roaming fees). It starts fast, gets you back to the last pair or list you were examining.
