You have tried a blocker before. It held for a week, then you turned it off. The right blocker is the one you can eventually stop using. In a Pew Research Center survey of 9,750 U.S. adults, Bishop and colleagues (2026) found that 45% had tried to cut back on their phone in the past year, and about one in four of those called the attempt very successful. The Offline.now Matrix is a self-reflection framework that maps your motivation to change your phone habits against your confidence that you can, and sorts the result into four types, each with its own starting place. This comparison is written for the Overwhelmed type, with a line for Ready near the end.
Offline.now is a directory of therapists and coaches who work on screen and phone use, and the home of the Offline.now Matrix, a two-question self-reflection framework that finds your starting place. The Matrix supplies the criteria below. No criterion is weighted so that any product wins. A blank cell means we could not verify the fact on October 23, 2026.
Why compare blockers on these criteria?
Because they predict what happens after you stop paying. Our earlier comparison asked whether screen time apps help, or just add more to manage, and it settled on four questions. Does the tool change the environment, so the pull is weaker without you doing anything? Does it leave a skill behind, so you are different when it is gone? Does it add a system to maintain? Is there evidence for the approach, even if there is no study of the product itself?
This post adds two columns: price as of a stated date, because subscription prices move, and the type it fits, because a tool that suits one reader will fail another.
How do the seven options compare?
Mechanisms come from each vendor’s own site or App Store listing. Prices are what we could read on October 23, 2026. Where a page could not be reached, the cell is blank.
| Option | Mechanism (vendor’s description) | Changes the environment | Leaves a skill | Adds a system | Evidence | Price as of Oct 23, 2026 |
|---|---|---|---|---|---|---|
| iOS Screen Time, Android Digital Wellbeing | Built into the phone: a usage report, per-app limits, scheduled downtime | Partly; limits can be dismissed with a tap | No | Yes, a report to read | No trial of either feature found; see Goodday (2026) on trackers | Free, included with the phone |
| Opal | “Instantly Block apps and websites you choose at a specific time of day.” Deep Focus “can’t bypass or cancel” | Yes, during a session | No | Yes, sessions and schedules to set | No published trial of Opal found; closest evidence is Castelo (2025) on timed blocks | US App Store listing: US$19.99 monthly, US$99.99 yearly |
| one sec | “A mindful pause before you can open distracting websites,” and the same for apps | Partly; the app still opens | Yes, the pause is a habit you practice | Low | A six-week field study of 280 users, Grüning and colleagues (2023), with the app’s developer as a co-author | Essentials free; paid tier priced inside the app |
| Brick | A physical device; apps you choose are blocked while the phone is “Bricked” and return when you tap the phone on the Brick | Yes | No | Low once modes are set | No published trial found; closest evidence is Castelo (2025) | US$84 one time; Brick Night US$184 |
| Cold Turkey | Windows and macOS blocker for “social media, games, apps, YouTube, or the entire internet”; Pro adds scheduled and locked blocks | Yes, on the computer only | No | Low | No published trial found; closest evidence is Castelo (2025) | Blocker Free at no cost; Pro CA$49 one time (“Pay once, own forever”) |
| ScreenZen | “Delay before opening your app,” with the wait growing each time you open it; optional block at a daily goal | Partly; the app still opens | Yes | Low | No published trial found | Free; optional tips of $5 to $40 |
| Forest | “Plant a seed,” and “if you cannot resist the temptation of using your phone and leave the app, your tree will wither” | No; it rewards, it does not block | Partly, for focus stretches | Yes, sessions and a forest to tend | No published trial found | Free with in-app purchases; US App Store: $5.99 monthly, $35.99 annual |
What does each option actually do?
Screen Time and Digital Wellbeing report and limit
Both phones ship with a usage report, per-app time limits and a downtime schedule. They cost nothing. The weak point is the same on both: when a limit arrives, one tap extends it. For many people the weekly number is the whole experience. This is the free baseline. If a paid tool does no more than this, the money bought a prettier report.
Opal blocks on a schedule
Opal blocks the apps and sites you choose at times you set. Its listing describes Focus Sessions synced with the phone’s Focus Mode, and a Deep Focus level that cannot be bypassed or cancelled while it runs. That is a genuine environment change for the length of the session. It also asks for upkeep: sessions to schedule, allowances to adjust. The US App Store listing shows $19.99 a month or $99.99 a year. Opal’s own pricing page could not be reached on October 23.
one sec adds a pause
one sec sits between your tap and the app. The vendor describes it as “a mindful pause before you can open distracting websites,” with the same concept on the phone. The app still opens if you want it to. Each pause is a small rehearsal of noticing the urge and deciding. It is also the one app here with a published study of its own. In a six-week field study of 280 users, Grüning, Riedel and Lorenz-Spreen (2023) found that one sec cut actual opens of the chosen apps by 57 percent, and a follow-up experiment with 500 people found the option to dismiss the attempt did most of the work, with the time delay second and the reflective message adding little. One limit travels with it: the app’s developer is a co-author. The essentials are free; the paid tier is priced inside the app and the site does not show it.
Brick puts the switch in the room
Brick is a small physical device. You set up modes in the app, choosing which apps and sites are blocked or allowed, and the phone stays in that state while it is “Bricked.” Unbricking requires tapping your phone against the Brick, so the switch lives wherever you left the device. The design moves the decision out of your pocket and onto a shelf. The vendor’s site lists Brick at US$84 and a newer Brick Night, which blocks chosen apps automatically when you enter your sleep space, at US$184 (prices read October 23, 2026).
Cold Turkey locks the computer
Cold Turkey Blocker runs on Windows and macOS. It blocks websites, applications or the whole internet, and the Pro version adds scheduled blocks and locking features so a block cannot be lifted early. It does nothing for the phone in your hand. For a reader whose problem is the laptop at 11 p.m., that is the right scope. Blocker Free costs nothing and includes a seven-day trial of Pro; Pro is CA$49, “Pay once, own forever” (vendor pricing page, October 23, 2026).
ScreenZen makes each open slower
ScreenZen inserts a delay before a chosen app opens. You can set the wait to grow each time you open the app that day, and you can set a daily goal that blocks the app when you reach it. It is the closest free option to one sec. The developer lists no subscription, only optional tips from $5 to $40 on the US App Store.
Forest rewards the stretch
Forest is a focus timer. You “plant a seed,” it grows while you stay in the app, and “if you cannot resist the temptation of using your phone and leave the app, your tree will wither.” Forest does not block anything. It rewards a stretch of attention, which suits work sessions more than bedtime scrolling. The US App Store lists it as free with in-app purchases, with a $5.99 monthly and a $35.99 annual Early Bird plan.
What does the research support?
The best evidence is for a block with a start and an end. In a preregistered randomized trial of 467 adults, Castelo and colleagues (2025) blocked mobile internet on participants’ phones for two weeks. Daily screen time fell from 314 minutes to 161 during the block, and sat at 265 two weeks after it ended. Ninety-one percent improved on at least one measured outcome. About a quarter of participants kept the block on for 10 of the 14 days, and the benefits held for people who slipped. The block worked because the environment changed.
Trackers on their own are a weaker bet. In a perspective piece, Goodday and colleagues (2026) argue that health trackers and apps have mostly delivered data, and data alone rarely changes behavior. This is expert opinion, so it carries less weight than a trial result.
The goal is to stop needing the tool. Suchy and colleagues (2026) interviewed 31 adults about how mental health apps fit into daily self-care. The best outcome in the sample was the person who no longer needed the app. Thirty-one interviews cannot say how common that is. They do say what to aim for.
Short breaks have mixed results. Reviewing 21 studies of digital detox, Radtke and colleagues (2022) found some improved well-being and others changed nothing. Apart from the one sec field study, none of these studies tested the products in this comparison. What they support is an approach: a block that changes the environment for a set period, and a practice you can carry after the block ends.
Which blocker fits your type?
The type decides the tool. Overwhelmed means high motivation and low confidence, so you genuinely want to change, and what you’ve tried hasn’t stuck. For that reader a hard lock is a risk, because the first bypass confirms the story. What the Overwhelmed type needs is a small win that is visible by Friday. A pause tool does that. So does one scheduled block on one app for one hour.
The Ready reader can hold a hard block. Brick or Cold Turkey will be used as designed, and the environment change does most of the work. The question for Ready is scope: the phone or the computer.
| Type | What the week needs | Fits |
|---|---|---|
| Overwhelmed | One small, visible win | one sec or ScreenZen on one app; or an Opal session on one app, one hour, one week |
| Ready | A lock that holds | Brick for the phone, Cold Turkey for the computer |
| Either, wanting the free baseline first | A number to react to | Screen Time or Digital Wellbeing for one week, then decide |
Lasting change runs on confidence, not willpower. A blocker bypassed once a day spends confidence. A pause honored most of the time builds it. If you want a healthier relationship with your phone without another system, pick the tool with the lowest upkeep that still changes something.
Frequently asked questions
Do app blockers actually work?
Blocks with a set start and end have the best evidence. In Castelo and colleagues’ 2025 trial of 467 adults, a two-week mobile internet block cut daily screen time from 314 to 161 minutes, and the gains partly held two weeks later. Of the apps here, only one sec has a published field study of its own, and its developer co-authored it.
Opal or one sec?
They do different jobs. Opal blocks chosen apps during scheduled sessions, so it changes the environment while a session runs. one sec adds a pause before a chosen app opens, so it builds the habit of noticing. For the Overwhelmed type, the pause is the lower-risk first step.
Is Brick worth it?
It depends on whether you will use it as designed. Brick moves the switch out of your pocket and onto a physical device, which is a real environment change. For the Ready type that is often the whole solution. For the Overwhelmed type the first emergency release can feel like a failure, so start with a pause tool and come back to Brick when a block has held for a week.
Where do I start?
Start with the two questions at offline.now/start. They sort you into one of four types, and the type decides which tool fits. The Find Your Starting Place worksheet does the same thing on paper.
If you want a different way to change your screen habits, one with no shame and no judgment, Offline.now was built for you. This comparison does not crown a winner, because the right tool is the one that matches your type and that you can stop using once the practice has moved into your life. If a tool has not stuck before, that is information about fit, and what actually works for phone addiction when nothing else has is usually a smaller step than the last attempt.
Start with the two questions at offline.now/start. They take about a minute and sort you into one of four types, each with its own starting place. The Find Your Starting Place worksheet does the same thing on paper: one page, free to download, no email required. After the quiz, the Offline.now Program is the next step. Use it on the web and by email, with no download. There is no streak to lose and no password to remember.
If you want a person in the loop, the Offline.now directory lists therapists and coaches who work on screen time.
Offline.now provides coaching-oriented guidance, not diagnosis or medical advice. If digital habits are creating significant distress, working with a qualified practitioner is a strong next step. The Offline.now expert directory is a good place to start.
