It is very good application.
But when I try to add currency it is not possible to add more then one. Type currency rate that you are interested in using following scheme:
example: eurusd=x and you have the exchange.
When I try to add second it is open in new page and when press back it is no appear in main page.
And one suggestion is it possible when click on stock or currency rate to be possible to see graph for last 1 day, 5 day, 1M, 3M, 6M, 1Y.
As it is in Sense because HTC stocks tab stop working. See attachment
Edit: I found it - when I click on the currency from second page it is appear on the first page. So now stay my request to add history.
