Reviewers largely praise Todoist for doing one thing very well: capturing and organizing tasks quickly without extra complexity. They repeatedly call it simple, fast, reliable, and easy to use across devices, with strong natural-language entry, recurring tasks, integrations, and enough flexibility for personal use or small teams. Several say they keep coming back to it after trying heavier tools. The main criticisms are that it feels behind on AI and automation, some advanced planning features are missing, and parts of collaboration, guidance, pricing, or calendar support could be better.
