What is Todoist?
Todoist is one of the longest-standing task management apps (founded in 2007!). You get exactly what you'd expect from Todoist — the ability to create tasks, prioritize them, and organize them with labels. You can view your tasks in a list, kanban view, or calendar view (paid tier).
With the rising popularity of time blocking, Todoist has received immense pressure from it's customers to build a calendar view and allow for task time blocking. That said, time blocking is a secondary feature to Todoist and is quite barebones compared to other daily planners. Many folks integrate Todoist with Sunsama or Akiflow for the full daily planning experience.
If considering Todoist for business, whether you're an individual or a team, there are better task management apps available that will give you more productivity power (e.g. other tools that will allow you to schedule meetings, time block tasks, manage projects, see your workload, and collaborate with team members), so as a heads up, make sure to consider those before diving head first into Todoist for business.
