The Windows Phone Blog reports that the official Fidelity Investments app, described as "a powerful mobile solution providing you with news and trading tools in the palm of your hand", is now available for Windows Phone. The app offers Fidelity customers access to their workplace savings account and the ability to trade stocks, options and mutual funds.

Even if you're not a Fidelity customer the apps still services a useful general pupose financial news and information tool, supplying the latest news from a range of industries, as well as real-time stock quotes, and interactive stock charts.

A stand out feature is the excellent support for Live Tiles. Individual stocks and securities can be pinned to the start screen and will update automatically to show the latest prices. The tiles will also change colour (red or green) to reflect pricing trends and, for double size tiles, flip to show related news headlines. 

Colour is used thoughtfully throughout the app to enhance the display of information, but it also makes the app more attractive and eye-catching than the typical financial data app, reflecting the high quality design of the app. The quality of data on offer, as you would expect from a big name brand, is excellent and should be one of the key draws for this app.
