The problem with Slack and the like is that it's communication based, not work based.

The problem with Todoist and Wunderlist and the like is that it's work based, not communication based.

Slack is awesome at communicating. But it has no checklist, no todo, no collaboration tools that fulfill most needs. They're all half baked.

Wunderlist has checklists and todos and can be used to track collaboration efforts by linking Google Docs or Sheets to a task for example, but communication is still horrible. It's nowhere close to being a main communications channel.

So most end up using a combination of apps.

But this is also one of the greatest detriments to productivity. Having to juggle apps.
