The best app blockers in 2026, tested against the evidence
If you only buy one blocker, buy Cold Turkey for desktop-only distraction (one-time ~$39) or Freedom if your procrastination hops between laptop and phone (~$40/year). The right pick depends on where you leak time and how good you are at defeating your own defences, so match the tool to the leak, not the marketing.
| Cold Turkey | Strictest desktop blocker, one-time ~$39, no mobile. For serial self-negotiators on Windows or Mac. |
|---|---|
| Freedom | Cross-device sync, subscription ~$40/year or one-time Forever plan. For laptop-plus-phone leakers. |
| Opal | Polished iPhone blocking with hard-to-quit Deep Focus, ~$99.99/year. For iPhone-first procrastinators. |
| one sec | A forced breath before each app opens, roughly €14.99/year. For unconscious, habitual openers. |
| Forest | Gamified deterrent, a tree dies if you leave, one-off ~£3.99 on iOS. For students and light cases. |
How we ranked them
Three criteria, in order: how hard the block is to defeat once you regret setting it, whether it covers the devices where your procrastination actually happens, and total cost over two years. Polish and dashboards came last, because a beautiful blocker you can bypass in two taps is a screensaver.
Cold Turkey: the strictest, desktop only
A locked Cold Turkey block survives restarts and blocks its own uninstaller, which makes it the only mainstream blocker that reliably beats a determined future you. Pro is a one-time purchase of around $39, cheaper over two years than any subscription here. The trade-offs are real: no mobile apps at all, and no escape hatch if you legitimately need a blocked site mid-block. Pick it if your distraction lives on a computer and you have a history of switching softer blockers off.
Freedom: one blocklist, every device
Freedom runs the same session across Mac, Windows, iOS, Android and Chrome at once, so blocking a site on your laptop does not just move the scrolling to your phone. Scheduled recurring sessions make blocking a default rather than a daily decision. It is softer than Cold Turkey on desktop and its iOS filtering leans on a VPN profile some users find flaky. About $8.99/month, ~$40/year, with a one-time Forever plan that is often discounted. Pick it if your distraction spans devices.
Opal: for iPhone-first procrastinators
Opal's Deep Focus sessions are meaningfully harder to cancel than Apple's tap-through Screen Time prompts, and its focus reports give you a number to watch. At around $99.99/year for Pro it is the most expensive tool on this page, the Android version is far weaker, and your laptop is untouched. Pick it only if your procrastination is overwhelmingly on an iPhone and the tap-through habit is costing you real hours.
one sec: friction instead of a wall
one sec does not block anything: it makes you take a breathing pause before a distracting app opens, then asks if you still want in. That targets the autopilot open, which is most phone procrastination, and it is the only tool here with a randomised controlled trial behind it (Grüning and colleagues, 2023, PNAS). It will not stop deliberate bingeing, and iOS setup via Shortcuts is fiddly. At roughly €14.99/year it is the cheapest paid option. Pick it if your problem is unconscious opening rather than chosen scrolling.
Forest: the gentle gateway
Forest plants a virtual tree that dies if you leave the app, turning phone avoidance into a small game with visible stakes. It is willpower-based at heart, you can abandon a tree in two taps, so it ranks last on hardness. But for students and lighter cases the loss-aversion nudge plus Pomodoro-shaped sessions is often enough, and the iOS one-off price of about £3.99 makes it the cheapest experiment on this list.
Who should skip all of these
If you procrastinate with the blocker installed by finding new distractions, the problem is the task, not the app: an aversive or vague task will always find an unblocked outlet. Start with why the task repels you, break it down, or use body doubling instead. Also skip blockers if you have never measured where your time goes; a fortnight of RescueTime data will tell you which of these tools, if any, you actually need.

Frequently asked questions
What is the hardest app blocker to bypass?
On desktop, Cold Turkey with a locked block: it survives restarts and blocks its own uninstaller. On iPhone, Opal's Deep Focus is the hardest mainstream option. No blocker survives a second, unblocked device, so cover every device you own or accept the leak.
Are free app blockers good enough?
Sometimes. Cold Turkey's free tier blocks websites but can simply be turned off, one sec's free tier covers a single app, and Forest's Android free tier is usable. If you defeat your own defences, the paid locked modes are the actual product.
