Is there an iPhone app that lets you plug in the number of shares you own and your cost basis so that you can see your gains and losses in real time?

For example, let’s say I bought 20 shares of KO at $50 per share. Now KO is selling for $45 per share. If I log on to my Fidelity or Scottrade or whatever account, I will see that I’m down $200. What I want is an app that I can plug that information into so it will show me the $200 loss according to the current price of the stock. I know Fidelity and most brokerage firms have their own apps that would do this, but I don’t feel comfortable using an app that is connected with my actual account. I’m looking for something where I can plug in the information manually that isn’t linked at all to my real accounts.
