Ive been using
yahoo finance for years. The desktop version and iPhone app. Both are great and love the improvements on new iPhone app. I just wish yahoo went into brokerage business so I dont have to keep entering my purchases in yahoo. Tda (3 versions of apps. Lol), Etrade, and Optionshouse stink. Actually the next best app is Robinhood which is an app that you can trade stocks on for no commissions. Go figure, the 2 free sites have the best apps!!
