Website Blockers That Actually Hold: Freedom, Cold Turkey, Opal and the Built-Ins

Every website blocker works on the day you install it. You are motivated, the block is new, and the site you were wasting time on is just gone. The test is three weeks later at 3pm, when you have a genuine reason to check the site, you open the blocker to make an exception, and you discover how many clicks stand between you and undoing the whole thing.

That number is the product. We compared the current options on it, and on what the paid tiers buy beyond a timer, because all of them have a free version and most people do not need to spend anything.

Start with what is already installed

Your phone and laptop both have blockers built in. On Apple devices it is Screen Time: App Limits, Downtime, and a website restriction list that syncs across your iPhone, iPad and Mac. Android has Digital Wellbeing with app timers and a Focus mode. Windows has Focus sessions in the Clock app, which is more of a timer than a blocker but does silence notifications.

All of them are free and worth a week's trial. All of them share one weakness. When the limit hits, there is a button — Ignore Limit, Remind Me in 15 Minutes, whatever the platform calls it — and you set the passcode yourself, so you can always get past it. For some people that friction is enough. For the rest of us, three weeks in, that button is being tapped on reflex, and the built-in has quietly become a notification rather than a wall.

A blocker is only as strong as the hardest step to switch it off. If that step is a button you can press, it is a reminder.

Cold Turkey: the one that does not let you out

Cold Turkey Blocker is a Windows and Mac app with a reputation for being the strict one, and the reputation is earned. A locked block cannot be ended early: not by quitting the app, not by restarting, and with the strictest options not by changing the clock or uninstalling. It blocks at the system level rather than as a browser extension, so switching browsers does not help either.

The free version blocks websites, with exceptions, timed blocks and statistics, and for a lot of people that is the whole job. Pro is a one-off purchase — $39 when we checked, though the pricing page shows the structure rather than the number — and it adds the things that make it a complete tool: blocking applications as well as sites, scheduled blocks that recur, breaks and allowances, and the full set of locking methods. One licence covers both operating systems, with lifetime updates.

The trade-off is that it is a desktop tool. It does nothing for your phone, and if the phone is the problem, you need one of the next two. It also has no account and no sync, which is either a limitation or exactly what you wanted.

Freedom: every device, one schedule

Freedom's argument is coverage. One account blocks on Mac, Windows, iOS, Android and Chromebook, with no limit on the number of devices, and a session you start on one can apply to all of them. Sessions can be scheduled and recurring — 9 to 12 every weekday, say — which is the feature that removes the daily decision, and Locked Mode stops you ending a session early from the app.

The free plan gives you basic blocking. Premium is $8.99 a month, $3.33 a month if you pay yearly, or $99.50 once on the Forever plan, which was half its usual price on the day we checked. There is a seven-day trial. If you have three devices and a habit that follows you between them, this is the simplest way to put one wall across all of them.

Its lock is softer than Cold Turkey's on the desktop, and on the phone it is subject to the same platform limits as everything else. What it does better than anyone is the schedule: set it on Sunday night and the week's blocks just happen.

Opal: for the phone, and the most serious about it

Opal is a phone-first blocker for iOS and Android, with a Mac app, and it is built around the idea that the phone is where the day goes. The free plan gives you one rule — a schedule or a time limit — plus app blocking, basic timers and today's Opal Score. Pro adds unlimited rules, allow-only lists so that everything is blocked except what you name, score history, and Hard Mode.

Hard Mode is the reason to consider it. Opal describes it as no way out: you cannot turn Opal off. In practice it is the only phone blocker we have used where the mid-session temptation simply had nowhere to go. The price is the catch: $19.99 a month if you pay monthly, $99.99 a year if you pay yearly, or $399 for a lifetime licence. Never pay monthly; the yearly rate is about $8.29 a month, and the monthly plan exists to be avoided.

What we actually run

Cold Turkey Pro on the work laptop, with a scheduled block of the four sites that eat mornings, locked from 9 until 1. Screen Time on the phone, with the passcode set by someone else in the house. That combination cost $39 total, and the phone half is free. We tried Opal for two months and it was better than Screen Time on the phone; we stopped paying because the borrowed passcode did the same job for nothing. If you live alone, Opal is the honest recommendation for the phone.

Two things the tools cannot do for you. The first is choosing the list: block the sites you actually lose time to, not the ones you feel you should not visit, and be specific — the one subreddit rather than the whole of Reddit, if the whole is where the useful part lives. The second is deciding when the block runs. A blocker with no schedule is a decision you have to make every morning, and the morning you do not make it is the one that matters. Set it once, on a calm day, and let the calendar hold the line; our time-blocking piece covers how to pick the hours. The habit of reaching for the site outlives the site for about a week. After that, the wall is just where the wall is, and you stop testing it.

And if what you keep opening is not a website but a browser extension or a tab that is always there, the answer might be pruning the browser itself first — the extensions worth keeping is a shorter list than most people run.
