one sec and Munen are the two apps people mention when they want a pause instead of a wall. Both interrupt the moment you tap a distracting app. The difference is what decides the pause. In one sec, you do, once, per app. In Munen, your own recent behavior does, every night. This page lays out both so you can pick the one that matches how you actually fail with your phone.
one sec details come from one sec's public App Store listing, website, FAQ and help center as of September 2026. If anything is out of date, email support@munen.app and it will be corrected.
The short version
- one sec interrupts. When you open a flagged app it shows an intervention, by default a breathing exercise, and then asks whether you still want to continue. You choose the intervention type and its timing. It can also block apps completely in scheduled sessions and kick you out after a set time.
- Munen paces. When you open a flagged app it shows a pause of 0 to 10 seconds and then gives you a limited access window of a few minutes. Both values depend on a zone that is recalculated every night from how you used those apps the day before. Munen names the five zones from Pause (hardest day) to Flow (best day).
If you want a ritual you design yourself, at the same intensity every time, one sec is built for that. If you want the resistance to rise and fall with your week without you touching settings, that is what Munen does.
Side by side
| Munen | one sec | |
|---|---|---|
| Core mechanic | Adaptive friction: a pause of 0 to 10 seconds plus an access window of a few minutes every time you open a flagged app | Intervention on open: breathing exercise by default, then a "continue or close" choice |
| What decides the pause | Your zone, recalculated nightly from your usage of the flagged apps. You pick the overall intensity (gentle, balanced, firm) and a hard-day mode | You, per app: intervention type and when and for how long it appears |
| Intervention types | One pause screen that shows your own reason for using the phone less and one of the alternatives you chose (read, message someone you love, breathe) | Breathing (4-7-8, box breathing), mirror, rotate phone, type random text, math problems, conversational reflection. Types beyond breathing are Pro |
| After you get in | Access window of a few minutes, then the pause returns. Balanced intensity: 4 to 10 minutes depending on zone | Re-Intervention kicks you out after a set period; Emergency Brake for long scroll sessions |
| Complete block | Not by default. Optional firm hard-day mode closes flagged apps on your worst days, and you turn it on yourself | Yes, scheduled block sessions, bedtime blocks and strict block sessions (Pro, iOS) |
| Bad day handling | Zone moves at most one step per day; downward moves only at the nightly recalculation, never mid-day. A genuine effort day by 8 pm lifts you one zone from the two lowest zones | No automatic adjustment; the intervention stays as you configured it |
| Setup per app | Pick apps once from the native picker. No Shortcuts automations | Shortcuts automation per app on iOS. one sec 6.0 on iOS 26 says it can add them for you from "Add Intervention" instead of you building each one by hand. Screen Time API is used for blocking and shields |
| Reflection tools | Usage journal, streaks and achievements, an AI coach that knows your week (3 messages and 1 journal reflection per week free, generous use on Premium), SOS screen for the impulse moment | Journaling, intention tracking, emotion tracking |
| Websites | Not covered | Safari extension on iOS, browser extension on desktop (Pro) |
| Apps covered free | Up to 3 apps free, unlimited on Premium | 1 app free, unlimited on Pro |
| Account required | No for the free tier; only at checkout or first AI use | Account for cross-device sync |
| Where usage data lives | On the device; the zone is calculated on the device. Anonymous usage analytics are sent. AI features send what you write plus a summary of your week's numbers, only when you use them | Intervention logic runs on the device; one sec states it cannot look at your data. App Store privacy label: usage data not linked to identity |
| Platforms | iPhone | iPhone, iPad, Mac, Android (via Accessibility Service), browser extension |
| Free tier | Adaptive friction, zones, focus sessions, journal, streaks and achievements, SOS grounding, a weekly taste of the AI, 2 weeks of history | 1 app, breathing intervention, Re-Intervention on that app |
| Paid price | 4.99 USD/month or 39.99 USD/year, 14-day free trial | one sec FAQ: 3.99 EUR/month, 14.99 EUR/year or 99.99 EUR lifetime, with a 1-week trial and a student discount. App Store listing shows 2.99 to 4.99 USD/month and 19.99 to 29.99 USD/year |
| Availability | 132 countries; not in the EU, UK, Switzerland or South Korea | Worldwide |
Where each one fits
You want to design the ritual. A 4-7-8 breath before Instagram, a mirror before TikTok, a typed sentence before Reddit. one sec gives you a menu of interventions and lets you decide when each one fires. Munen has one pause screen and it does not let you pick the exercise; it shows your own reason and one of your alternatives instead.
You want the pause to react to your week. With one sec the breath is the same on a great Sunday and on a Thursday where you opened Instagram forty times. Munen's zone reads those forty opens overnight and gives you a longer pause and a shorter window the next day. A good week loosens it again. You can still step in and adjust the zone or the intensity yourself.
You need a wall at set hours. one sec's scheduled and strict block sessions close apps completely during a window. Munen's focus sessions do that on demand or on a schedule, but the rest of Munen is not built around fixed windows and never blocks by default.
You want websites and the desktop covered. one sec has a Safari extension and a desktop browser extension. Munen is an iPhone app that works on apps only.
You want more than one app for free. one sec's free plan covers a single app. Munen's covers three, with the full adaptive engine, zones, journal and focus sessions. Both put unlimited apps behind the paid tier.
Frequently asked
Can I use both? You could, but two pauses on the same app stack up and get annoying fast. Pick one mechanic per app. If you like one sec's interventions on one app and want Munen's adaptive pace on the rest, that works.
Does Munen have a breathing exercise? The pause invites you to breathe, and the SOS screen walks you through grounding steps when the urge hits. It is not a menu of exercise types like one sec's.
Does one sec adapt to my usage? Not on its own. You set the intervention and its timing per app, and it stays that way until you change it. Its Re-Intervention and Emergency Brake react to how long you have been in the app during the current session, not to your week.
Which one is cheaper? For one app, one sec's free plan is enough. For several apps, Munen's free plan covers three and its Premium is 39.99 USD/year after a 14-day trial. one sec Pro is 14.99 EUR/year per its own FAQ, with a lifetime option, as of September 2026.
How does this compare to a blocker like Opal? Both one sec and Munen keep the app reachable by default; Opal closes it during sessions. See Munen vs Opal.
Munen is free on the App Store. The friction engine and zones do not require an account or a subscription.
one sec is available at one-sec.app and on the App Store.
