Thanks for the question about this. For some context we drink a lot of coffee at my office. We have two pots (bold & light roasts). People never know when coffee is ready or brewing without going to the kitchen. We have a #coffee channel so people can post that they are brewing, but then we had issues with people stealing cups before the pot was done (don't do this).
So this app gives an interface for people to just click their face and the bot will handle it from there. It says that a pot is brewing, and 12 minutes later will post that the pot is ready.
To your point, it is just a mobile app with a slack integration. I built it to test out jasonette, which was a great experience, but I have no delusions of grandeur here.
