Todoist

Todoist is the most elegantly designed task management app available, striking a rare balance between simplicity and power. Natural language input is best-in-class -- typing 'review quarterly report every Monday at 9am p1' creates a recurring high-priority task instantly. The project hierarchy with sub-tasks, sections, and labels provides flexible organization without complexity. Karma points and goal streaks add lightweight gamification that genuinely motivates completion. The app is exceptionally polished across every platform including Linux, with reliable sync and offline support. Integration with 80+ tools including Google Calendar, Slack, and Zapier extends its utility into broader workflows. The API is well-documented for automation enthusiasts. App store ratings (4.8 iOS, 4.6 Android) are among the highest in the productivity category. For project management specifically, Todoist handles personal and small team projects well but lacks the timeline views, resource allocation, and reporting depth that larger teams need from dedicated PM tools. The free tier is functional but limited to 5 active projects. As a pure task management tool, Todoist is the best in class.
