Extremely Good

Would be 5 stars but:

No landscape mode (really).
Interface a little cumbersome until you get used to it. The way you need to enter the amounts is confusing until youve done it quite a number of times.

On the plus side, the comprehensive nature of the currencies included and the clear display of results are excellent.
