A calm, capable place for everything you have to do — a simple list when you want it, a full GTD system when you need it. And the only one that answers “am I actually keeping up?” with a number.
Free forever for the core. Premium is $24/year.
Tell us how you think about getting things done, and we'll show you Principal Task in your language. You can cross over anytime.
Just get things done. A to-do list that just works — type it, see today, check it off. No setup, no jargon, no learning curve.
See the simple way →New to staying organized? We'll show you a simple, opinionated way to get on top of everything — four easy habits, plain language.
See the organized way →Folders, contexts, priorities, statuses, and stars — the five dimensions, native. Built for next-action thinking and the weekly review.
See the GTD way →Context, folder, priority, status, and star — the five dimensions of every task. Capture loosely and stay flat, or organize tightly and slice by anything. Same tasks, your structure. New accounts come seeded with a few starter folders and contexts, so you're productive on day one.
Custom folders organize your tasks by project or area of focus.
Custom contexts to track where and how a task can actually be done.
Set a priority and star the tasks that can't wait, so your most important work stays in front.
Folders, contexts, priorities, statuses, and stars — all five dimensions visible at a glance.
Your Task Velocity score is the rolling 30-day ratio of tasks completed versus created. Above 1.0×, you're ahead. Below 1.0×, your list is growing faster than you can clear it. It answers “am I keeping up?” with a number, not a vibe — and the score is free for everyone.
Go Premium for Task Velocity history — your score charted over time and filterable by folder, context, priority, or status, so you can see exactly where the backlog is building.
Above 1.0× you're ahead · below 1.0× the list is winning.
Powerful when you want it, invisible when you don't.
Visualize your tasks in a Kanban board grouped by status, priority, folder, or context. Move work forward with a single drag — on mobile and web.

Group your activities with limitless nesting of tasks — organize as deep as your work requires.
Find your tasks using the included filters, or define your own to surface exactly what's actionable now.
Create recurring tasks and get reminders via in-app notifications or Pushover, so you're always on time.
Write task notes in enhanced Markdown — headers, checklists, links and more — to capture and organize your thinking, right on the task.
Every dimension, reminders, nested tasks, recurring, Markdown, custom filters and the Dashboard are free. Premium adds the rest.
