Is there any app or site there that simply shows the current price of my stock, the cost I put into it, and the difference all on one page?

I've created a spreadsheet that does this, but I have to continually enter the current stock prices manually.
I know this isn't the ideal way to analyze stock, but I would like to see the running total of my stock compared to what I've invested.

The portfolio page containing your stocks shows this. Whatever online brokerage you use.

The brokerage house you have an account with will show you that.

Your broker's web site should do this. Or you can automatically get the stock price with the "get data from the web" feature if you use Excel.
