After trying out many Slack apps, my team finally gives up and decides none of the current ones had what we needed. It should be easy to have a standup or daily without your tool getting in the way, but that apparently isn't the case.
Some of the tools touted the possibility, but for some reason have a ridiculous price point. After much deliberation we decide that we could create something that would work for us, and hopefully for others. We'll share it when it is ready. :)
