When looking for an app to scan barcodes, this came up in the search results. It's an app to manage all your keys. You can add pictures of them, give them descriptions, and put who they belong to. It's supposed to be for people who loan out keys often so they can keep track of who has what key and how many there are. But I don't see why you couldn't use this as an index of all your keys. I believe this works on all generations of iphones but this will only work on a fourth generation ipod touch. I don't know if this app is available for other smartphones. Below is what the app looks like and all the information you can fill in when you add a key.
