AN HONEST ANSWER FROM SOMEONE WHO BUILDS THE OTHER THING

Do app blockers actually work?

Yes. For about a week. Then most of them fail in a specific, boringly predictable way — and how they fail is the most useful information you’ll get all month, if you’re watching.

Fair warning about who’s talking: I build tools in the opposite direction, so treat me as an interested party. I’m going to try to be straight with you anyway, including about the parts where blockers win.

Start with what they genuinely do

A blocker adds friction between an impulse and an action. That is a real intervention, not a placebo. In the first week it usually works extremely well, and the reason is worth understanding: the block interrupts the automatic path. Your hand goes, the wall appears, and for a second you are awake. That second is the entire value.

There are situations where I’d tell you to install one today and not think twice:

When the stakes are high. Money, safety, something that could take a genuine bite out of your life. Protection is real and it beats philosophy. Get the wall up first and be interested later.

When you need a bridge. A hard deadline, a bad fortnight, a period where you have no spare capacity to be thoughtful. Blockers are excellent short-term scaffolding.

When the app is a slot machine. Some products are engineered against you specifically. Removing an unfair fight is not weakness.

So: not anti-blocker. Anti-only-blocker. Here’s where it goes.

The second month

The shape below is what I see, described from my own use and from people telling me the same story — not a measured curve. Treat the weeks as a sequence, not as data. What research does support is the direction: a systematic review and meta-analysis of digital self-control tools found that people routinely circumvent or disable the restrictions they set, and that these tools face attrition over time (Roffarello & De Russis, ACM Transactions on Computer-Human Interaction, 2023). The timing is mine; the pattern is not only mine.

1. WEEK 1 · IT WORKS

   The wall appears, you’re surprised every time, screen time drops hard. This feels like the problem being solved.

2. WEEK 3 · THE WALL BECOMES FURNITURE

   You stop being surprised. The block is now part of the scenery, and scenery doesn’t wake anyone up.

3. WEEK 5 · THE WORKAROUND

   The browser version. The other app. The five-minute extension you grant yourself at 23:50 and again at 23:55. You are now spending willpower on defeating your own security system.

4. WEEK 6 · THE BLEND

   You uninstall the blocker during a hard week, entirely reasonably, and nothing you learned stays behind — because nothing was learned. The wall did the noticing for you.

That last line is the one that matters. A blocker doesn’t make you better at catching yourself; it makes catching yourself unnecessary. Those are different outcomes and only one of them survives the blocker being gone.

What a blocker cannot see

It can see the action. It cannot see the job.

A behavior that shows up that reliably is doing something for you — relief from an unclear next step, escape, stimulation, certainty, a small hit of control, an hour that belongs to nobody else. The blocker removes the action and leaves the job completely untouched, still open, still needing a contractor.

So it gets subcontracted. This is why people who successfully block one app find themselves on a different one, or reorganising a folder, or refreshing an inbox with nothing in it, or lying awake running the day. There is no blocker for that last one. The job doesn’t care which door it uses.

It’s also why blocking can quietly make things worse. Being walled off from the thing you were reaching for, with no idea what you were reaching for, produces a low background irritation and precisely zero information. You end the month with better numbers and the same blind spot.

The distinction the whole thing turns on

Control forces an outcome. Agency is noticing early enough to get a vote on it. Patches are for software; people get explanations.

A blocker is control, and control is a perfectly good tool — I want to be clear that this isn’t a purity argument. It’s that control has a specific failure mode: it works exactly as long as it’s installed, and it teaches you nothing on the way. If you’re fine running it forever, run it forever. But most people install a blocker hoping to eventually not need one, and that particular hope is not what a blocker is built to deliver.

What the alternative actually is

Not willpower. Willpower at 23:52 is a losing position and anyone selling you that is not paying attention.

The place this is winnable is earlier — the missing frame, the ten seconds between the impulse and the action, wide enough for exactly one question:

What am I actually after?

Answer it honestly a dozen times and you start recognising the pattern before your hand moves, which is the only version of this that keeps working after the tool is gone. Sometimes the honest answer inside that frame is “a wall” — and then you install the blocker, on purpose, as a decision rather than a hope. That’s a completely different relationship with the same software.

And if you see the whole picture — what it gives you, what it costs — and scroll anyway, knowingly? That’s a win here. It’s your call. The only thing I’m against is it happening while you’re somewhere else, and finding out from the clock.

Questions people actually ask about this

Do screen time limits work on iPhone or Android?

They work the same way any blocker works: well while they’re surprising, poorly once they’re furniture, and not at all once you’ve learned the passcode-and-extend dance. The built-in ones are also the easiest to override, since you hold the key.

Why do I just find a workaround?

Because the job is still open. You’re not defeating the blocker out of weakness — you’re doing what the habit was hired to do, through whichever door is unlocked. The workaround is information: it tells you the need is real and unaddressed.

Should I use a blocker and something else at the same time?

That’s the sensible answer for most people. Keep the wall where the stakes are high, and separately practise catching the moment when they aren’t. One protects you now; the other is the part you keep.

What should I use instead of a blocker?

Nothing, first. Spend a week just noticing when your hand moves and what you were after — no restrictions, no targets. Most people find that the noticing alone changes the numbers, and it tells you which of the walls you were about to build is the one worth building.

That noticing is what I build for. Small apps, one moment each, designed to make the pattern visible and return the choice to you — apps that help you take your life back without trying to own the rest of your day.

I’m a founder and product builder, not a clinician. This can support reflection and change; it doesn’t replace qualified medical or mental-health care. Where the behavior involves money, safety, or genuine compulsion, a wall plus a professional beats a clever framework — take that seriously.
