If you are an avid iPad user, and you follow financial markets at all, you should definitely give StockTouch from Visible Market a try. Whether you are a financial pro or simply a budding investor, you will definitely find some really useful features here. In fact, the app was recently named the top finance app for the iPad in 2011 by Apple's App Store Rewind.
From our time with it, we found that the award was well-warranted. The dynamic charts that were designed taking cues from a video game engine were especially easy to follow. The ability to check the top 900 U.S. and Global stocks was handy. We really liked how easy it was to find tons of news that was specifically linked to your favorite stocks. This was amazingly useful. The app has such a huge plethora of fantastic features, there are simply too many to name them all. The only nitpick we had was that there was no auto-refresh for true "real-time" stock evaluations. (Either that or we simply couldn't find the preference for it.)
Regardless, this was a minor quibble and does not mar the versatility and feature-rich power of this great app! Check out the links below for more info.
