We're no Wall Street wizards -- we're more Kevin Bacon's character in his bike messenger days in Quicksilver than Vin Diesel in his Ferrari days in Boiler Room -- but in the final analysis, one thing's very clear: the iPhone's built-in Stocks app sucks, which you don't really come to realize and appreciate until after you've played with these heavier-duty options from AOL and Bloomberg. It leads us to wonder why it's there to begin with, and furthermore, why they've continued to work on it for 3.0 by adding landscape mode. Like the equally-weak Weather app, Apple would be better served by cutting Stocks out of the firmware and leaving it to companies that have the know-how and the vested interest in producing a quality product (like, say, The Weather Channel in place of Weather). As for the battle between Bloomberg and Daily Finance, they're both fantastically detailed with tons of options for tracking your portfolio, checking out a variety of chart time ranges in landscape view, staying up on corporate and world news, and keeping tabs on global indexes. Ultimately, we'd say they're neck-and-neck; since they're free, we recommend you download and try them both. We preferred the way that Daily Finance presented news for individual stocks -- on their own tab to reduce clutter -- and liked the fact that you have far more news categories available to you. On the flipside, we marginally preferred the high-contrast visual appearance of Bloomberg -- it seemed just a little more "professional" to us. Either way, though, do yourself a favor and relegate Stocks to some unused page at the very back of your home screen.
