Katalogz lets you manage a list that is as detailed as your imagination. Store anything from baseball cards to countries you've visited. It's as easy as logging in and creating a customized katalog. Start tracking your odds and ends or your most important data today!
Technically speaking, Katalogz is a masterpiece and a scalability nightmare. I achieved a way to create an infinite amount of "data models" encapsulated within a few tables. As awesome as this sounds it also starts to break down exponentially as the database grows, since everything is stored in the same place. I still use it to keep track of all of my little things, but on a consumer-use basis it isn't a feasable solution... but it is still very cool.
