The domain-list problem
The oldest and most common approach is a list of banned website addresses. It's simple to build and it genuinely worked reasonably well a decade ago, back when most exposure came through a small number of dedicated sites. It works far less well now, for one plain reason: a huge amount of explicit content today doesn't live on a site built for it. It shows up in search results, on social platforms, inside video apps, in places a domain blocklist was never built to reach.
Ask this question about any blocker you're evaluating: does it understand what's actually on the screen, or does it only recognise a fixed list of addresses? The first approach adapts as content moves. The second one is permanently one step behind wherever it moved to last.
What to actually check
- Does it work across apps, not just a browser? Most modern exposure happens inside apps that were never designed as porn sites. A blocker limited to browser traffic misses the majority of where this content actually shows up now.
- Can it be disabled from the notification shade or a quick toggle? If a blocker can be switched off in two taps with no friction at all, it functions more as a suggestion than a barrier. A real one should make disabling it require a deliberate, harder step, not a habit-compatible one.
- Does it need a password shared with someone else to be meaningful? This works for parents guarding a child's device. For an adult trying to build their own discipline, a shared-password model creates a dependency on another person rather than building the actual internal habit that outlasts any single piece of software.
- What happens to what it sees? A tool reading your screen content in real time is a serious permission to grant. Check plainly whether anything is recorded, stored, or transmitted, and read the actual privacy policy rather than trusting a marketing page.
- Does it survive a reinstall or a factory reset? A blocker that resets cleanly with the phone offers no real resistance at the one moment resistance matters most, the moment someone is motivated enough to want it gone.
The real test: imagine yourself tired, alone, at eleven at night, motivated to get past whatever is in the way. Would this tool actually survive that specific moment, or would it fold the instant it was inconvenient? Evaluate every option against that scenario specifically, not against how it looks on a features page.
How Qlean approaches this
Qlean reads on-screen text in real time, across every app, rather than relying on a fixed list of website addresses. When explicit content appears, it force-closes the app it's showing in, before the moment of engagement can properly begin. Nothing scanned is recorded, stored or shared; the reading happens in the moment and nothing else. It's built around the assumption that content will keep moving to new places, and a blocker needs to understand what it's looking at rather than memorise where it used to be.

The clearest way to judge any of this is to actually use it. A short free trial is built in, no card required.

Whichever blocker you choose, or even if you choose none, it's worth being honest that software alone was never going to be the full answer. A real barrier removes the easiest path, and that matters enormously, but the actual discipline, the routine, the accountability, the honest reckoning with what the habit was doing for you, still has to be built by you. Our guide on how to quit porn covers that fuller picture, with the blocker as one piece inside it rather than the whole plan.
Signs a blocker is not doing much
If disabling it takes less effort than the urge itself, if it only catches a fraction of what actually reaches you, or if you've stopped noticing it's even there, it's probably functioning as decoration rather than a real barrier. A blocker worth having should be one you occasionally feel mildly annoyed by, that mild friction, at the exact moment you want it gone, is the entire point. A real structural barrier like this is one of the factors most reliably linked to lasting success; see what actually predicts successfully quitting.
