"Want to stay on top of the market, but don't want to be chained to your computer? If you have an iPhone, you're golden, because apps have turned the iconic device into the ultimate market tool."

Several free or low cost apps that will get you all the info you need to get involved in the market, be it futures, commodities or even stocks. The one above, Currency Calculator, is even on sale for $0.99 USD and might also be handy if you are traveling.
