This is the best application to track stocks.
If you are looking for a simple way to track stocks, this application is a great option for you. The whole idea behind the application is that it will notify you whenever the price of the stock you are interested in will increase or decrease. This is really helpful if you are looking to make a profit or if you are trying to get out of a price level. The whole point is to keep you on top of the market and to let you know the moment the market makes a move.
