one sec vs ScreenBuddy: The Best one sec Alternative for iPhone
Two friction apps, one honest decision
- Friction strength: one sec adds a short breathing pause (about 5 to 10 seconds); ScreenBuddy uses a fixed 25-second countdown.
- Enforcement: one sec's iPhone setup runs through Shortcuts, which you can dismiss; ScreenBuddy runs on Apple's Screen Time framework, so apps stay locked by default.
- Daily limits: both offer them now, but ScreenBuddy's hard cap locks the app until midnight with no override.
- Platforms: one sec covers iOS, Android, and desktop; ScreenBuddy is iOS-only.
- Price: one sec is cheaper (about $19.99 a year, roughly $50 lifetime); ScreenBuddy costs more ($39.99 a year, $99.99 lifetime) but offers a pay-once option.
Is ScreenBuddy a good one sec alternative?
The best one sec alternative for iPhone is ScreenBuddy if a gentle pause has stopped working for you. one sec is cheaper, cross-platform, and its research pedigree is strong. ScreenBuddy is iOS-only and costs more, but its friction is harder to tap through: a longer 25-second countdown, a daily cap that locks apps until midnight, and enforcement that runs on Apple's Screen Time framework instead of dismissable Shortcuts. one sec is the gentler nudge. ScreenBuddy is the harder guardrail.
At a glance
one sec vs ScreenBuddy
Both apps come from the same school of thought: add a moment of friction between the impulse and the app, and a lot of mindless opens simply stop happening. Where they split is how hard that friction pushes back, and how easy it is to slip past on an iPhone.
| Feature | one sec | ScreenBuddy |
|---|---|---|
| Core mechanism | Breathing pause before apps open (adjustable, roughly 5 to 10 seconds) | 25-second countdown before apps open (fixed) |
| Daily time limits | Yes, on Pro (strict block, per-app budgets, doomscroll emergency brake) | Yes, hard daily cap per app, locks until midnight with no override, separate weekday and weekend caps |
| iPhone setup | Runs through the Shortcuts app | Runs on Apple's Screen Time (Family Controls) framework |
| Default enforcement | Gentle, you can dismiss the pause or turn the automation off | Apps are locked by default, the daily cap cannot be overridden |
| Platforms | iOS, Android, and desktop via browser extension | iOS only |
| Free option | One app free, forever | 3-day free trial on all plans |
| Monthly | About $3.99 | $3.99 |
| Annual | About $19.99 | $39.99 |
| Lifetime | Around $50 | $99.99 |
| Research | Independent Heidelberg and Max Planck study, about 57% fewer app opens | Uses the same friction approach with a longer pause and hard caps |
The short version: one sec costs less and follows you across more devices. ScreenBuddy is the stronger pick when the pause has stopped working and you want something on your iPhone that you can't casually wave away. Pricing is from each app's US listing as of July 2026 and varies by region.
How one sec works
How one sec Works, and Where It Slips on iPhone
one sec puts a brief intervention between your tap and the app. You reach for Instagram, a breathing exercise or a reflection prompt appears for a few seconds, and then you decide whether to keep going or back out. The free tier covers one app. Pro (about $19.99 a year) adds unlimited apps, extra intervention styles, a strict block mode, per-app time budgets, and a doomscroll emergency brake that pushes you out after a long session.
The approach has real evidence behind it. An independent study run with the University of Heidelberg and the Max Planck Institute found that adding a short pause before opening selected apps cut app opens by about 57% over roughly six weeks. That is the strongest published result for the pause-before-opening method, and it is a big reason one sec earns its reputation.
The catch on iPhone is how the pause is delivered. On iOS, one sec works through the Shortcuts app. Shortcuts was built for convenience, not self-control, so the automation shows a dismissable banner, and it can be switched off in Settings in a few taps. For a mild habit, the gentle nudge is often enough. If you have already caught yourself tapping straight through the breathing exercise on autopilot, or the Shortcuts automation keeps breaking, that is usually the moment people start looking for a one sec alternative with more teeth. Our honest one sec review after 30 days goes deeper on living with it day to day.
How ScreenBuddy works
The iOS-Native Difference
ScreenBuddy is built only for iPhone, and it uses that focus to enforce harder. Instead of Shortcuts, it runs on Apple's Screen Time (Family Controls) framework, the same system Apple uses for its own restrictions. That means the apps you choose stay locked by default. Opening one starts a 25-second countdown, and you watch the timer before the app will open. Fifteen extra seconds over one sec's pause does not sound like much, but it gives the impulse more time to fade.
The second layer is the daily limit. Set a 30-minute cap on Instagram, and once you have spent it, the app locks until midnight with no override button and no way to buy back time in the moment. You can set different caps for weekdays and weekends. The countdown handles the individual impulse. The limit handles the pattern of drifting back in ten times a day.
Both apps lean on the same behavioral idea, the one Stanford researcher BJ Fogg formalized as B = MAP: a behavior happens when motivation, ability, and a prompt line up at the same moment. Friction quietly lowers ability, so the reach for the phone fizzles before it becomes a 40-minute session. ScreenBuddy's bet is that on an iPhone, friction you can't dismiss in two taps does that job more reliably.
Pricing
one sec Is Cheaper, ScreenBuddy Enforces Harder
There is no way around it, one sec is the cheaper app. Its annual plan runs about $19.99 against ScreenBuddy's $39.99, and its lifetime plan sits near $50 against ScreenBuddy's $99.99. one sec also gives you one app free forever, while ScreenBuddy offers a 3-day free trial on every plan rather than a permanent free tier.
So the money question is straightforward. If price is the deciding factor, one sec wins, and it is a genuinely good app. ScreenBuddy asks you to pay more for a specific trade: native iOS enforcement that is harder to bypass, a longer countdown, a hard daily cap, and a $99.99 lifetime option for people who would rather pay once and never see another subscription. Whether that is worth double depends entirely on whether the gentle version has been working for you.
How to choose
Who Should Switch, and Who Shouldn't
Switch to ScreenBuddy if you are on iPhone and the pause has stopped changing your behavior. If you tap through one sec's breathing exercise without thinking, if the Shortcuts setup keeps breaking, or if you want a daily cap that actually locks you out instead of nudging you, the native enforcement is the upgrade you are looking for. It also fits people who want the simplest possible setup: pick your apps, set your limits, done, with no accounts or automations to maintain.
Stay with one sec if you use Android or a desktop browser, since ScreenBuddy is iOS-only and cannot help you there. Keep it too if your habit is mild and a light nudge is all you have ever needed, or if the lower price and the free single-app tier matter most to you. one sec's research pedigree and cross-platform reach are real advantages, and for a lot of people the gentle version is exactly right.

Other options
Other one sec Alternatives Worth a Look
ScreenBuddy is not the only option if one sec isn't fitting. A few others, depending on what you need.
-
ScreenZen
Free with no paid tier and friction-based like one sec, with a slightly different flow. It's the natural first stop if budget is the main issue.
-
Opal
A polished, iOS-first blocker with deep focus modes and detailed stats, though it's the most expensive of the group at around $59.99 a year and adds social features many people don't need.
-
Freedom
Works across phones and computers and locks whole sessions, which suits people whose distractions live on a laptop as much as a phone.
Bottom Line
Which One Wins?
Neither app wins outright, because they solve the same problem at different strengths. one sec is cheaper, works everywhere, and has the research pedigree. If a gentle pause changes your behavior, it is an easy recommendation.
ScreenBuddy is the better one sec alternative for the specific person who has already tapped through the pause too many times on iPhone. The longer countdown, the hard daily cap, and enforcement that runs on Apple's Screen Time framework are harder to wave away. If that is you, ScreenBuddy is on the App Store with a 3-day free trial.
Frequently Asked
FAQ
What is the best one sec alternative for iPhone?
For iPhone specifically, ScreenBuddy is the closest alternative that enforces harder. It uses a longer 25-second countdown and a hard daily limit, and it runs on Apple's Screen Time framework rather than Shortcuts, so the gated apps stay locked by default. ScreenZen is the best free alternative, and Opal is the most feature-rich if you don't mind the higher price.
Is ScreenBuddy better than one sec?
Neither is better in every case. one sec is cheaper, works on iOS, Android, and desktop, and has strong published research behind its pause. ScreenBuddy is iOS-only and costs more, but its friction is harder to tap through and its daily cap locks apps until midnight with no override. If a gentle pause works for you, one sec is enough. If you keep slipping past it, ScreenBuddy adds the enforcement one sec's default setup does not.
Does one sec have daily time limits like ScreenBuddy?
Yes, one sec Pro now includes strict block, per-app time budgets, and a doomscroll emergency brake. The difference is enforcement. one sec's iPhone setup runs through Shortcuts and can be dismissed or turned off, while ScreenBuddy's daily cap runs on Apple's Screen Time framework and cannot be overridden once you hit it.
Which is cheaper, one sec or ScreenBuddy?
one sec is cheaper on every tier. Its annual plan is about $19.99 versus ScreenBuddy's $39.99, and its lifetime plan is around $50 versus ScreenBuddy's $99.99. Monthly pricing is roughly the same at about $3.99. one sec also has a permanent one-app-free tier, while ScreenBuddy offers a 3-day free trial.
Does ScreenBuddy work on Android?
No. ScreenBuddy is iOS-only. If you need something for Android or a desktop browser, one sec is the better fit because it runs across iOS, Android, Mac, Windows, and Linux from one account.
Is the pause approach actually backed by research?
Yes. An independent study run with the University of Heidelberg and the Max Planck Institute found that adding a brief pause before opening selected apps reduced app opens by about 57% over roughly six weeks. That study evaluated the one sec mechanism. ScreenBuddy uses the same underlying friction approach with a longer countdown and added daily limits.
