App blocking
Programs on your list close instantly if they are opened during a session.
Stop getting distracted. Start getting things done.
BlockFocus blocks the apps and websites that steal your time (games, social media, video) for as long as you choose. Try to open them and they close instantly.

How it works
- Pick what distracts you. Add programs (Steam, Discord, games) and websites (YouTube, Instagram, TikTok), or use the ready-made lists in one click.
- Choose how long. 25, 50 or 120 minutes, a custom time, or Pomodoro (25 minutes of focus + 5 minutes of break).
- Focus. Blocked apps close the moment they open and blocked sites won't load. When time is up, everything opens again automatically.
What it does
Website blocking in every browser
Works at the network level (tested with Chrome, Edge and Firefox), not a browser extension that can be switched off in two clicks.
Ready-made lists
Social media, Video, Games, Chat: add a whole category with one click.
Pomodoro timer
25 minutes of focus, 5 minutes of break. Blocking pauses during breaks automatically.
Statistics and session summary
Focus time today and this week, your streak of focused days, and what you were kept away from.
10 languages, light and dark
The interface speaks 10 languages and follows your light or dark theme.

$19.99
One-time payment, 3 computers. All 1.x updates included.
Checkout opens soon. You will be able to buy Pro here as soon as checkout opens. Until then every feature of the free version can be used with no time limit.
Pro is a one-time payment, not a subscription.
Is it impossible to get around?
No, and no blocker can promise that: an administrator can always stop a program. BlockFocus is built to add enough friction that giving in to a distraction takes more effort than getting back to work. Hard mode makes that friction much stronger.
Download
Windows 10 and 11 (64-bit). Website blocking needs administrator rights; the app asks once.

VirusTotal scan (2026-09-29): 3 detections from 70 antivirus engines. The detections are automated (heuristic) guesses common for unsigned programs; Microsoft's has been reported as a false positive. The network driver the program uses (WinDivert) is listed as a “risk tool” by some antivirus products. View report
The app is not code-signed yet, so Windows SmartScreen may warn you the first time you run it. Click “More info”, then “Run anyway”. You can check the file with the SHA-256 value above.
Frequently asked questions
Is the free version really free?
Yes. App blocking, website blocking, ready-made lists, Pomodoro and statistics are free forever, with no time limit.
What do I get with Pro?
Hard mode, scheduled sessions, profiles, allowlist mode, breaks and the weekly report. One payment, no subscription.
How do I activate Pro?
After purchase you receive a license key by e-mail. Open BlockFocus, click the tray icon, choose License… and paste the key. The first activation needs an internet connection once; after that the app does a short renewal once a month, and Pro keeps working for 60 days without internet. No account is needed.
I lost my license key.
Use the “I lost my key” button in BlockFocus, or write to our support address from the e-mail you used at checkout.
Can I use it on more than one computer?
Yes, on 3 computers. If you replace a computer, use “Remove from this computer” in the License… window on the old one to free its place; if you can no longer reach it, write to us.
Does it work in every browser?
Website blocking works at the network level, so it doesn't depend on a browser extension. It is tested with Chrome, Edge and Firefox. If Chrome's “Use secure DNS” is set to a custom “secure-only” provider, some sites behind Cloudflare may get through.
What if I really need to stop a session?
Normal sessions can be ended at any time. In hard mode, use Emergency exit and type the random text shown. Nobody can get locked out: sessions always end when their time is up.
Why does it need administrator rights?
Website blocking works at the network level, which Windows only allows for administrator programs. App blocking alone doesn't need it.
Does BlockFocus collect my data?
No. Your lists, history and settings never leave your computer. The free version sends nothing. Pro sends only your license key and a one-way fingerprint of your computer when it activates and once a month when it renews. The optional update check is off by default and only downloads a version number.
What is your refund policy?
You can get a full refund within 14 days of purchase, no questions asked.
