The pile goes away. One thing comes back.

A list of forty tasks is a paralysis machine when your brain will not pick. One Thing takes the whole pile, asks a short series of questions, and returns a single task with the rest hidden until it is done.

Triage is the whole interface, not a view option you have to remember to switch on. There is no backlog screen to open in a weak moment, because the screen that shows you everything is the thing that was hurting.

§ I

§ I — The program

Take the whole pile.
Hand back one.

What One Thing does with everything in your head, what it refuses to do to you afterwards, and the word attached to a price that is not printed yet.

Dump it in the order it falls out

Everything: the errand, the email you have reread four times, the vague dread with no name yet, the thing that is only a thing because someone mentioned it in March. It goes in unsorted, unpunctuated, and in whatever order your head releases it.

There is no project to file it under and no field you must complete before it will accept the next one. Sorting at the moment of capture is a tax on the one part of this you were always able to do.

The pile

A short series of questions

Then the pile is triaged — not by you staring at it and feeling the weight, but by answering a few small questions about each thing in turn. How long is it really. Does it matter this week. Is it actually yours to do. Is it, on inspection, not actually a thing.

Small questions are answerable when large ones are not. Deciding what to do next out of forty options is the task you cannot start; deciding whether one item takes two minutes or two weeks is a task almost nobody freezes on.

The triage

One task, and the rest genuinely hidden

What comes back is a single task. Not a list with one item highlighted, not a filtered view you can widen — the rest is put away until this one is done, because a list you can peek at is a list you will peek at.

Nothing was lost to hide it. Everything you dumped is still held, still yours, and comes back one at a time in the order the triage decided. Finish the one on the screen and the next one arrives.

The one

Nothing here is keeping score

No streak to break, no badge to earn, no chart of the days you managed it and the days you did not. A week where you opened this twice is not a debt, and there is nothing in here that will treat it as one.

That is a design decision rather than a missing feature. Anything that counts your consistency eventually punishes you for the weeks that are hardest, and this is built for people who have already been punished by enough software.

No score

The word attached to a price that is not printed yet

Pricing published before launch. There is no figure on this page because there is no figure yet, and inventing one to make a page look finished is how a product starts lying before it ships. When there is a price it is printed here first, plainly, before anything can be bought.

It will not be a trial that becomes a subscription while you are not looking, and there will be no tier holding the useful half of your own pile behind it. Thirty days, money back, no reasons asked attaches to whatever price is published — it is a term of the house, not a courtesy that can be withdrawn.

Your tasks stay on the device. No ads, no streaks, no productivity guilt. We will not add an account requirement later, we will not sell what you dumped, and we will not use it to train anything.

The house's word

The pile was never the problem. Being asked to choose from it, forty times a day, with the part of your brain that does not do choosing — that was the problem, and it is the only thing this program takes away.

Standing prohibitions

Five things One Thing will not do, held as terms of the program rather than as a roadmap that can quietly change.

  • No streaks, badges, or confetti — a day you did nothing is not a debt to us
  • No backlog screen, no project tree, no nested sub-tasks to maintain
  • No notification engineered to bring you back for our sake
  • No feed, cohort, or leaderboard — nobody else sees what is in your pile
  • No ads, no data sold or brokered, and nothing you dumped used to train a model
§ II

§ II — The price

Published before it is
charged.

What a price will be attached to, printed while there is still no price to print.

Pricing at launch

Announced at launch

One Thing is not priced yet. The figure is published on this page before launch and before anything can be bought — no trial that turns into a subscription, no tier holding half your own pile back, and thirty days to ask for the money back on whatever the figure turns out to be.

The terms

  • Pricing published before launch
  • Your tasks stay on the device
  • No ads, no streaks, no productivity guilt
§ III

§ III — Questions

Asked, answered,
printed.

The questions people who have already uninstalled six task apps actually send before they will put a seventh on a phone.

I have quit every productivity app I ever downloaded. Why would this be different?

Because the others asked you to build and maintain a system, and maintaining a system is the exact thing your brain will not do reliably. There are no projects to set up here, no tags to keep tidy, and no weekly review to fall behind on. You dump, you answer a few short questions, you get one task. If you vanish for three weeks, nothing has decayed and nothing is owed — the pile is simply where you left it.

What if the one thing it hands me is not the one I want to do?

Pass on it and the next one comes. It is a handed-over task, not an order, and the triage is not claiming to know your day better than you do. The value is not that the choice is correct; it is that you are looking at one thing instead of forty and can answer yes or no to it in a second.

Where does the rest of the pile go? I need to know nothing is lost.

It is all still there, on your device, in the order the triage put it. Hidden is not deleted — nothing you dump is ever dropped, summarised away, or quietly aged out. The rest is out of sight because seeing it is what stopped you, not because we stopped keeping it.

What is this going to cost?

The price is published on this page before launch, and nothing can be bought until it is. There is no trial that becomes a subscription and no tier that holds part of your own pile back. Whatever the figure is, thirty days to ask for the money back comes with it.

Is this treatment for ADHD?

No. One Thing is a focus tool, not a medical device, and nothing in it is diagnosis, treatment, or medical advice. It does not assess you, it has no opinion about your symptoms, and it is not a substitute for a clinician. If getting started is consistently costing you work, relationships, or health, that is worth raising with one.

The register

Be written in for the day One Thing opens.

One address, kept on our ledger and used twice at most: the day the price is published, and the day it ships. No newsletter follows it, and it is never attached to anything you dump into the app.
