There's a bit more to the story than simply solving a problem. I have other plans for the software and we have ideas about how we want to move it forward.
One of the key features is being able to "tag" an item on someone's wish list as "bought" or "buying". This allows others viewing the list to know that item has been taken. But there's also a requirement that the original author of the list/item cannot see that it has been bought otherwise there's no element of surprise for them come time to open the gift(s) :-)
Still, I highly doubt that there are not any apps that do this already. I mean, my family uses Amazon wish lists and set it so that you can't see when stuff is purchased.

Spreadsheets don't enable that privacy/secrecy.
