Kudos on creating something. It looks like it will be slick, and the impression is that it will be nice to use. But ... No way of trying it without registering? No way of seeing what it looks like? No list of "cards" in the system? Can I add new data? There's very little information to make a decision as to whether to invest time and effort in registering and then learning.
