Todoist

Todoist is the most-installed task manager across all platforms, trusted by 40 million users in over 150 countries. Its natural language input instantly parses dates, projects, and priorities from phrases like "Meeting with Sarah tomorrow at 3pm #work p1," saving an average of 10 seconds per entry compared to manual input. The Karma system gamifies completion, and the API powers more than 100 integrations. Unlike Linear, which focuses on team workflows, Todoist excels at individual task management — and its parent company Doist remains fully remote, profitable, and VC-free, a rare achievement in SaaS.
