Block any site, in any browser
Add a domain or paste a URL and it is blocked at the network level, so the same block applies in Chrome, Firefox, Brave, Samsung Internet and in-app browsers at the same time.

Website blocking
The website blocker for Android that blocks every browser at once
Appcognito is a free website blocker for Android. Block any site by URL, category or keyword, and its on-device firewall stops blocked sites loading across Chrome, every other browser and the in-app browsers inside other apps, with nothing about your browsing ever leaving your phone.
Every browser Chrome, Firefox, in-app browsers and more
On-device A real firewall, nothing routed to a server
Apps + sites Block websites and the apps behind them
More than a website blocker
Most site blockers only touch one browser, or only block apps. Appcognito blocks websites and apps together, on-device, across everything.
Block by keyword too
For pages a list has never seen, keyword blocking reads the visible on-screen text in real time and steps in the moment a blocked topic appears, even on a brand new site.
- New sites
- Search results
- In-app content
Four ways to block a website
Block on impulse, on a timer, on a schedule, or in bundles. Pick what fits the moment.
Quick Block
Block a website in one tap when you need to focus right now, then flip it back just as fast.
Focus sessions
Lock your chosen sites away for a set time. With an optional code, you cannot reopen them early.
Automation
Block sites automatically by time, Wi-Fi, charging or place, so the rule starts without you lifting a finger.
Profiles
Bundle a whole set of sites, apps and keywords into one profile and switch them on together.

Blocked sites simply do not load
Matching requests are dropped before the page opens. Everything else loads as normal, and nothing about your browsing leaves your device.

Website blocking FAQ
How do I block a website on Android?
Install Appcognito, add the site, domain or category to your block list, and its on-device firewall stops that site loading across every browser and app, not just one. There is no account and nothing leaves your phone.
Does it block websites in Chrome and other browsers?
Yes. Because Appcognito blocks at the network level on your device, the block applies everywhere at once, including Chrome, Firefox, Samsung Internet, Brave and the in-app browsers inside other apps.
Can I block a whole category of sites, not just one URL?
Yes. You can block individual domains, and you can also block by keyword so pages about a topic are blocked even on sites you did not list. The built-in Adult Content profile blocks over 750,000 adult sites in one tap.
Will it block apps as well as websites?
Yes. The same firewall blocks distracting apps and websites together, so you can shut out a social network's app and its site at the same time. Most blockers only do one or the other.
Is the website blocker free?
Yes. Blocking apps and websites works on the free plan with no time limit. Pro adds unlimited profiles and automations, accountability locks and uninstall protection.
Can I stop myself unblocking a site in a weak moment?
Yes. Start a Focus session with a lock code, or with Pro add a parental or partner accountability lock and reboot-proof uninstall protection, so a site you blocked stays blocked.
