They have a live free app that you can download, play with, and give feedback on. So far so good.
However, it appears you have to create an account to interact with the app at all, which is not in the spirit of Show HN.
If a new startup posted a Show HN that required giving a live email address, they would be criticized for it (and most people probably wouldn’t go any further).
EDIT: it would be great if one of the founders could create a dummy account that we could log in with. That's something other founders have done in the past, and it would be more in the spirit of Show HNs:"Please make it easy for users to try your thing out, ideally without barriers such as signups or emails. You'll get more feedback that way.
