one sec vs Cohesive

Most of the category disagrees with Cohesive about almost everything. one sec is the interesting exception, because it starts from a premise we’d sign: the reach is the moment that matters, not the total.

Where the two part company is what you do with that moment.

First, the practical fact: one sec is released and Cohesive is not. There is no version of “switch” available today. If you’re choosing something to install this week, install one sec.

What one sec does

From one sec’s own pages, as of 31 July 2026:

• Friction before the app opens. Instead of blocking outright, it interrupts — a deep breath, a mirror reflection, typing something, a conversational prompt — so the automatic reach has to become a deliberate one.
• Scheduled blocking too, if you want it. It can block distracting apps on a schedule.
• Platforms. iOS, Android, and a browser extension for Windows, macOS and Linux, with cross-device sync.
• Pricing. A free tier, described on their site as the essentials, plus a paid “one sec pro.” We couldn’t verify a current figure from their own pages, so we’re not quoting one — their store has it.

The design is genuinely thoughtful. Putting a second between impulse and action is the smallest intervention in the category, and small is a virtue here.

What Cohesive does

Nothing at the fork. That’s the whole difference.

Cohesive isn’t present when you reach for the app. It’s what you open afterwards — often minutes later, sometimes the next day — to record what happened and what was around it. Two taps, and that’s a complete session. If you continue, one question you can answer by remembering something. At the end, everything you said comes back and you decide whether any of it is worth keeping, in your words.

What accumulates isn’t a count of interruptions survived. It’s a short list of sentences about what matters to you, which you can edit and export.

Where they genuinely differ

one sec asks: was this reach deliberate? A good question, asked at the only moment it can be asked, with a mechanism sized to the two seconds available.

Cohesive asks: what was this reach standing in for? A question that can’t be asked at the fork — you have no attention to spare there — so it’s asked later, when remembering is possible.

The second question has an answer the first can’t reach. The first has an effect the second can’t have. Neither of these is a criticism.

Side by side

	one sec	Cohesive
Available now	Yes	No — waitlist only

Free tier	Yes	7-day full-access trial (planned)
Paid	“one sec pro” — see their store	€92.99 once, or €14.99/mo (planned, not active)

Could you use both?

Yes, and it’s the combination that makes the most sense of any in this category. They don’t overlap: one sec is at the fork, Cohesive is after it. One makes the reach deliberate; the other works out what the reach was about.

That’s not a sales line — it’s the honest read, and it’s also why we don’t think of one sec as a competitor so much as the other half of the same observation.

Which one to pick

Pick one sec if you want something today, you want the reach itself slowed down, you don’t want to be locked out of your own apps, or you want the same behaviour covered on a laptop as well as a phone.

Wait for Cohesive if the friction is no longer the problem — you already pause, you already know you’re doing it, and the question you’re stuck on is what you’d rather be doing instead.

If that second description fits and you want to try the idea now, you don’t need us: catch one moment and write down what was around it. A notes app does that.
