I just purchased this app today and wanted to share it. It is called iBullion. Basically, you enter the amounts of precious metals you have, and it keeps a running total for you. You can enter the price you paid and it will keep up with you gains and losses. It can also be password protected. It is basically just an electronic copy of your collection. It defiantly isn't for everyone, but I really enjoy knowing how much my stack is worth at all times.
