Irkless for Getting Things Done
If you run GTD, the lists you expect are already there: an Inbox, Someday, Waiting For, Delegated and a review that walks you through every project. You don't have to build them from tags and filters first.
Capture: everything into the Inbox
Press n and type it in one line. Call the plumber #calls friday
lands in the Inbox, tagged and due Friday. On a Mac, a shortcut catches it from any app;
on an iPhone, the share sheet or Siri.

Clarify: empty the Inbox when you have a minute
Take each item in turn and decide where it goes: a project, Today, Someday, Waiting For, Delegated or the bin.

Organise: lists that match the method
Areas for the parts of your life, projects inside them, subtasks inside those. Waiting For holds what you're expecting from someone; Delegated holds the jobs you've handed off and still need to chase.

Someday / Maybe
Ideas you might get to, out of sight until you want them.
Contexts as tags
#calls,#errands,#computer, nested if you like.A tickler that runs itself
Give a task a start date and it stays hidden in Upcoming until then.
Due dates only when they're real
Start and due are separate, so a deadline means a deadline.
Reflect: a review that walks you through
Each project has its own review interval. Review puts the ones that are due in front of you one at a time, the most neglected first. Tidy it, mark it reviewed, step to the next. Why the weekly review matters

Engage: Today, on purpose
Anytime holds every next action you could do. Today holds just the ones you've picked, grouped by area, so the list you work from in the morning is short enough to trust.

On every computer you use
The same lists in any browser, in the terminal, and in the Mac and iPhone apps (private beta). Moving from another GTD app? Bring your tasks with you, or see how Irkless compares with Nirvana, Things 3 and OmniFocus.
