WOW is this app gorgeous! I didn't get it at first because I didn't think I had any use for a stock app when I saw it under New & Noteworthy once, but now that it's free I decided to give it a try. It's universal for both iPhone/iPad. Lets you look at US/global stocks, has this great interface, and the sounds are a nice touch too. Can't wait until my dad gets home so I can share the wealth!
