I have been using Wikinvest for several weeks now on my 9900 and am quite impressed. The app allows you to both track your portfolio as well as look up quotes. It also has a news feed for the stocks in your portfolio, news feed for the markets, and a screen showing the performance of the various markets. I don't use the website often but there is a website where you can view all of the same info from the app as well as create manual portfolios such as a watchlist (brokerage accounts can be added in the app, manual portfolios have to be created on the website). If you pull up a particular stock, the page view is decent containing a performance chart, day range, 52 wk range, headlines,analysis, and financial data…not as extensive as going to my eTrade webpage but for an app, more than sufficient. You also get a weekly performance email, containing portfolio performance and your top performers and worst performers of the week. Finally, for those who have accounts with multiple brokers, its serves as a nice hub when you want a quick update on all your accounts or is a solution for brokerage firms that don't have a stock app. Oh, and its free.
