Todoist — To-do list & calendar

Todoist is a task management app that helps users capture, organize, and complete tasks across all devices. The iOS app provides quick task entry, project organization, due date scheduling, and priority flagging. What differentiates Todoist is its natural language processing — users type "Call mom tomorrow at 5pm" and the app parses the task, date, and time automatically. The app scales from simple personal to-do lists to complex team project management.

Todoist's interface is minimalist to the point of disappearing — the focus is entirely on tasks, not the app containing them. The red accent color signifies priority and urgency without overwhelming. Task entry appears instantly from any screen, prioritizing capture speed above all else. The visual hierarchy surfaces what's due today while keeping future tasks accessible. Projects and labels provide structure without mandatory organization — users can be as simple or complex as their needs require. The design respects that productivity apps fail when they become work themselves.

• **Natural Language Input**: "Email report every Friday" creates a recurring task with the correct due date. This reduces the friction of date pickers and dropdowns for users who think in sentences rather than forms.

• **Quick Add Shortcut**: The persistent "+" button enables task capture in under 3 seconds. Speed matters because ideas are forgotten if capture feels burdensome — Todoist optimizes for inbox zero mentality.

• **Priority Levels**: Four priority levels (P1-P4) with color coding enable triage without complex systems. Users can ignore priorities entirely or use them heavily — flexible structure accommodates different workflows.

• **Smart Scheduling Suggestions**: When adding tasks, the app suggests dates based on patterns ("next Monday" based on typical usage). This accelerates scheduling while maintaining user control.

• **Karma Points**: A gamified productivity score rewards task completion and consistent habits. The system provides motivation without punishing missed tasks — positive reinforcement only.
