The Top 20 Investing Apps for the iPhone and iPod Touch

Stock trading has gone mobile. Today you can research top stocks to buy, keep tabs on your portfolio, and execute trades from pretty much anywhere. That's thanks in large part to the popularity of mobile devices like the iPhone and Blackberry in the business world.

But with so many applications out there ― more than 50,000 for iPhone alone as of last count ― it's hard to tell which ones are worthwhile and which are just worthless. That's why we've compiled this list of the best Investing Apps for the iPhone…

Now, with today's release of the iPhone 3G S, traders will be able to make market moves even faster than before in addition to checking the Penny Sleuth's Twitter page…

Here's a look at some of our favorite FREE applications for the iPhone and iPod Touch. While we can't provide an exhaustive list of every investing application available for the iPhone and iPod Touch today, this should get you started with investing on the go:

1. Apple's Stocks App
One of the biggest changes in Apple's just-released iPhone 3.0 software was the newly improved Stocks app.  The reason that this app took the number-one spot in our Investing app countdown is simple: everyone has it.

Since Stocks comes on every single iPhone and iPod Touch that leaves the factory, it makes a whole lot of sense to use this program to keep track of your portfolio and find news and share data on top stocks market. The single best addition to Stocks is the interactive chart feature that you can access by holding your phone or iPod horizontally. 

2. iSwim and E*Trade Mobile Pro
iSwim and E*Trade Mobile Pro are two new apps that are available free of charge from Thinkorswim and E*Trade, two of the more popular brokers out there. If you're a client, you can execute trades in real-time from anywhere where you have cellular or Wi-Fi service, something that sets these two apps apart from the slew of apps that just provide quotes.

If you're not a Thinkorswim or E*Trade client, you can still download these apps and use them to check out quotes on stocks and options.

3. Bloomberg
If you're on the lookout for economic and investing news, Bloomberg's self-named application is your best bet. That's because addition to the standard stock quotes that all the rest of our top apps can provide, Bloomberg offers a feed of its award winning financial news service.

While the app isn't quite as versatile as the company's Bloomberg Anywhere app for Blackberry users who have a $1,700 monthly subscription to their professional service, the free iPhone app is definitely still worth checking out.

4. iTrade Stock Market Simulator
If you're looking for a way to trade without putting your money on the line, the iTrade Stock Market Simulator might be a good solution for you. The app gives you a $100,000 virtual stock portfolio that you can use to hone your investing skills.

iTrade also features real-time stock quotes and investment research to make the trading simulation as realistic as possible.

5. Morningstar
Morningstar's investment application is one of the newest additions to the stable. The app features investing ideas provided by the analysts at Morningstar.com. It's also the app that's most adept at providing data on mutual funds.

6. Forbes Intelligent Investing
One of the more interesting investing apps on the iTunes App Store is Forbes' Intelligent Investing. The entertaining program contains a repository of Forbes articles, including market forecasts and commentary, and ― more importantly ― one-on-one investment videos with the pros.

7. Black Gold
If commodities are your cup of tea, Black Gold should be on your iPhone or iPod Touch. The app features mobile price-watching and charts for crude oil, gold, natural gas, and heating oil.

8. FX360
FX360 is a mobile window into the world of currency trading. This free app offers real-time forex quotes and commentary from the minds at Global Futures and Forex. If you're new to trading currencies, the analysis you'll find at FX360 should give you enough guidance to get your feet wet in the FX game.

9. TheStreet.com Mobile
If you're a Jim Cramer fan, you shouldn't miss TheStreet.com Mobile. This app lets you download your favorite news, commentary, and analysis from TheStreet.com, and read it on the go ― even when you're not within range of cellular service. TheStreet.com Mobile's Cramer section offers articles from the "Mad Money" guru as well as access to continuously updated market data.

10. iStockManager
Are you a TD Ameritrade customer? If so, iStockManager lets you perform real money trades with your TD Ameritrade account. While this piece of software isn't from the broker itself, it does offer a number of attractive features like streaming level II quotes, option chains, and account information. The iStockManager software is also available for Blackberry.
