Ask HN: Anyone recall a simple project dashboard web app seen here last year?

Last year a startup was discussed here offering an incredibly simple shared tasks web app. I think it had a charcoal background.

The idea was a single page a team could glance at to see what the current tasks or priorities are. There may also have been an activity stream for individuals' updates, though I don't recall for sure.

This was not a full project collaboration tool like http://www.nozbe.com, and far simpler than even https://taskant.com/.

It was more like a pinboard of note cards of what a team should be working on.

The minimum viable product aspect and black background stuck with me, but I can't recall the name or even search terms to look for it.

Any ideas what web app I'm thinking of?
