one sec vs Naze: Two Ways to Pause Before an App Opens

Quick answer: Choose one sec if product-specific peer-reviewed evidence, browser support, and a choice of intervention styles matter most. Choose Naze if you want to name the reason for opening an app, choose how long you need, and then decide whether the open still makes sense.

These apps are closer to each other than a traditional hard blocker. Both add friction between an impulse and the app. The key difference is what they ask you to do with that pause.

Platforms	iOS, Android, and browser extensions	iPhone and Android
Websites	Browser extension support	Phone apps only
Best fit	Varied friction and research-backed self-nudging	Concrete intentional use for apps you still need

How one sec works

One sec intervenes when you try to open a selected app or website. Depending on your setup, it can show a breathing animation, mirror, text task, rotation prompt, conversational reflection, or another form of friction.

After the intervention, you can dismiss the opening or continue. One sec also offers blocking, a “re-intervention” feature for long sessions, intention tracking, emotion tracking, and browser extensions.

The range is a real strength. If one type of pause becomes too familiar, you can change it. Browser support also makes one sec more useful for people who move from a phone app to the same service on a laptop.

What the one sec study actually found

One sec has an advantage that should be stated plainly: it has product-specific peer-reviewed evidence.

A 2023 study in Proceedings of the National Academy of Sciences followed 280 people who used one sec throughout a six-week field experiment. The researchers reported:

36% of attempted target-app openings were dismissed after one sec intervened.
Opening attempts fell 37% from the first week to the sixth week.
Combined, actual target-app openings were 57% lower after six weeks.

The paper also ran a preregistered online experiment with 500 participants to separate the parts of the intervention. The explicit option to dismiss the opening had the strongest effect. The short delay also reduced consumption. The deliberation message by itself was not effective in that experiment.

That nuance matters. It is tempting to summarize the study as “a mindful message cuts usage by 57%.” The study supports the complete one sec intervention, not every reflective prompt in every product.

It also analyzed people who completed all six weeks in its main field results. As with any behavior-change study, results for an individual can differ.

How Naze works

Naze makes the intended use more concrete before the app opens:

Select an app you want to use more intentionally.
When you try to open it, choose why.
Choose how long the task should take.
Continue with that plan or leave.

The combination of reason and duration is the distinction. A reason answers what am I here to do? The duration answers how much time does that task deserve?

This is useful for mixed-purpose apps. YouTube can be a tutorial and a Shorts feed. Instagram can be a message inbox and an endless stream. Reddit can contain one saved answer and an hour of detours.

Naze does not have a published peer-reviewed product study comparable to one sec’s PNAS paper. Choose one sec if that evidence is your deciding criterion.

The biggest difference: varied friction or a concrete plan

One sec gives you several ways to interrupt the open. The intervention itself is the main event.

Naze uses one tighter flow to turn the open into a plan. The reason and chosen duration are the main event.

If your automatic behavior is very fast and repetitive, a breathing delay, mirror, or physical action may break it more effectively. If your problem is that useful and unplanned use blur together, stating the reason and duration may give you a clearer boundary.

Choose one sec if…

Peer-reviewed evidence is important to you.
You want several intervention styles to rotate.
You need a browser extension for distracting websites.
You want re-intervention after a set amount of time.
A direct dismiss-or-continue choice is enough to change the behavior.

One sec is the honest winner on research depth and intervention variety.

Choose Naze if…

You want to record the purpose before access.
You want to decide the session length before the feed appears.
You still need the app for messages, tutorials, work, or another defined task.
You prefer a consistent, minimal flow instead of selecting among many intervention types.
You want the habit to become “use with a plan,” not simply “wait before use.”

Which is better for YouTube?

It depends on the failure point.

Choose one sec if you need an intervention before the app and another interruption after you have been watching for a set time. Its browser support is also useful if you move to youtube.com.

Choose Naze if you want to define the session before it starts: “watch the saved repair guide for 12 minutes,” for example. That is a different goal from blocking YouTube completely.

For a hard iPhone limit, Apple’s Screen Time may be more direct than either tool. See our guide to blocking YouTube on iPhone.

Can you use one sec and Naze together?

You may be able to, but stacking two interventions on the same app can become cumbersome. A clearer setup is to give each tool a different job, such as one sec for browser distractions and Naze for selected phone apps.

Start with one tool and one app. If the behavior changes, keep the setup small. Complexity can become another reason to turn everything off.

Frequently asked questions

Are one sec and Naze the same kind of app?

They are both friction-based screen-time tools, but the interaction differs. One sec offers varied interventions and a dismiss option. Naze asks for the reason and intended duration before access.

Is one sec scientifically proven?

A 2023 PNAS study found meaningful reductions among six-week one sec users, including 57% fewer actual target-app openings by the end of the field period. That supports one sec as a complete intervention. It does not prove that every pause app produces the same result.

Has Naze been studied in a peer-reviewed trial?

Naze does not currently publish a peer-reviewed product-specific outcome study comparable to one sec’s PNAS paper.

Does Naze work on Android?

Yes. Naze is available on Google Play as well as the App Store.

Which one should I try first?

Choose one sec for research-backed intervention variety and browser support. Choose Naze for a focused reason-and-duration flow before phone apps open.
