I'm disappointed with the majority of the stock market apps out there. Mainly, the charting sucks! Lets start a thread on what apps we've found useful: Daily Finance (Brand New!) - DailyFinance is by AOL. It's website is DailyFinance.com and I actually like it! You can get news and good quality charts, although they are line charts rather than bar or candlestick. Gives real time intraday quotes (major plus). The details section gives lots of good info about your stock. Also allows you to view biggest movers (gainers and losers) in the 3 big markets (NYSE, NASDAQ, AMEX). Lacking: Like to see more on commodities and currencies. Includes some, but the charting only allows intraday. Like to see bar/candlestick capabilities. Get rid of large menu icons while viewing charts so we can see them bigger on screen. Add some technical analysis capabilities. So far, this has been my favorite app. iStockManager (TD Ameritrade) - Bravo to Ameritrade to bring a trading app to the Android market. It's truely awesome and the best in all aspects as compared to the rest of the market apps. The only reason this great app isn't my favorite is that it provides delayed data (20 minutes delayed) unless you have an Ameritrade account. Also doesn't provide commodity or currency info (you can't trade those at Ameritrade anyways). So if you wanna see how your stock is doing mid-day, you don't get live data. But for checking out daily charts after hours, it can't be beat. I love this app for charting only. Allows bar/candlestick and lots of technical analysis. Charts fill up screen and look good! Stock Quote - This program has come a long way since it's beginnings. Uses Google charts, but allows bar/candlestick charting with some basic TA. One of the major downfalls is that it's difficult to keep looking at new stocks. Gotta keep going back and forth with windows. Also doesn't remember chart preferences and everytime you have to go into settings to tell it you want candlestick/bar with TA whenever you pull up a new stock. Allows good live info on commodity futures and currencies. This could be a good app if developed further. Basically, it gives really good charts and info, but you really have to work for it each time! Google Finance - Basic program. Gives live info. It's fast to pull up for some quick quotes. Horrible charting. But very easy to use. I use this most often during the day when away from my home computer to keep track of some stocks because it's so fast and easy. DOW Jones and Nasdaq 100 - Two programs for quickly looking up gainers/losers, 52 week high/lows, opening gaps, biggest volume stocks, etc. You cannot type in individual stocks, but you can research the ones that have made the list above. Delayed quotes (but live on indexes). Cool app for researching stocks afterhours. You only get the ideas for stocks from these apps, but you need to use another program to really research stocks. So, what have you other traders discovered out there?
