Not A Browser vs one sec

25 August 2026 · facts checked against public sources on that date

one sec is the gentlest tool in this comparison set and the one people are fondest of. It intercepts you as you open something, makes you take a breath, and then asks whether you still want to.

It is aimed at a specific failure, it hits it precisely, and the browser is not that failure.

The failure it is built for

There is a particular way of using a phone that everybody recognises and nobody decides on. Your hand goes to your pocket. The phone is unlocked. The app is open. You are scrolling. At no point did a thought occur that you would describe as wanting to do this, and you could not say what you were looking for.

one sec puts a breath in that gap. Not a block, since you can always continue, just enough delay to let the deciding part of you catch up with the doing part.

For that behaviour it works, and the reason it works is that there was never any intention to override. The autopilot only wins when nothing interrupts it, and a few seconds is enough of an interruption.

Two different kinds of losing an hour

Here is the distinction the whole page rests on.

The unconscious hour. Forty minutes of scrolling you cannot account for. No decision was made. Friction fixes this, because there is no intent for it to fight.

The deliberate hour. You opened the article somebody sent, which was a perfectly reasonable thing to do. You read it. Then there was a link at the bottom, and a search bar at the top, and you followed one thing to the next for an hour. Each individual step defensible, the whole thing an accident.

A breathing exercise does nothing for the second kind. Every step you would be pausing before is a step you have a legitimate reason to take, and you will breathe and proceed, correctly, every time. The pause has nothing to catch.

The second kind is what a browser produces, and it is the one Not A Browser is built for. Not by making the reading harder, but by making sure that when the article ends there is nowhere to go next.

Asking versus not asking

There is a design difference underneath this that is worth naming.

one sec asks you a question at the moment of temptation: do you really want to open this? That is a reasonable question and it is being put to the least reliable version of you. tired, at the end of the day, holding the phone already.

Not A Browser asks nothing, ever. There is no prompt, no timer and no decision, because there is no address bar to decide about. The choice was made once, in daylight, when you set the default browser.

Neither approach is universally better. Asking builds awareness, which is worth having. Not asking is more reliable, and gives you nothing to learn from.

Pricing, briefly

one sec is free for one app, which is a genuinely fair free tier, so you can find out whether the mechanism works on you at no cost. Beyond that it is around $2.99 a month, or roughly $50 once for lifetime access.

The lifetime option is the interesting one. In a category about spending less of your attention, a recurring charge sits a little oddly, and the tools that offer a one-off price (one sec's lifetime tier, and Brick's hardware) are quietly the better-aligned ones. Not A Browser has no price to compare yet, which sidesteps the question rather than answering it.
