Professional and amateur investors, take note. Google's free Finance for Android app streams U.S. stock quotes, business news and data charts to your phone, and syncs with your Google Finance portfolios. The latest version adds the ability to sync multiple accounts, making it a must-try for all Google Finance users who need access to data and trends on the go via their Android device.

That said, there's a fair amount of "buyer beware" warnings attached to the app. Only U.S. stocks are supported, which makes it a no-go for all global investors (and, frankly, who isn't these days?)

Plus, with the recent upgrades made to the Google Finance web site, here's hoping Google improves this app to match; importing your portfolios results in some data corruption issues, and you can't see the net gain or loss to your investments as a whole.To boot, some quotes I viewed were more than 10 minutes old. Plus, the service runs in the background, draining battery life.

That said, your mileage might vary. If you're already using Google Finance to store and work with your portfolios, give the app a try. If not, the Android marketplace offers many other apps to track stocks in a much more friendly, consistent way (Stock Alert anyone?).
