There are a fair few Burndown products for Trello, including our existing Corrello Agile Dashboard tool. But most of them are pretty basic, and Corrello has a lot of features some teams just don't need. So... we decided to pull the Burndown Charts out of Corrello, along with our daily email and Slack updates. For teams that want the best Burndown Charts for Trello, but don't need all the other stuff Corrello brings with it!

Nice work. Love that it puts data front and center each morning via slack and email. I'm sure it would help teams avoid that "last day of the sprint" update.
