Website & app blocking

Block a site, an app, or one YouTube channel.

Add twitter.com to the blocklist and every browser on your machine refuses to load it. Block a single YouTube channel and the rest of YouTube still works. Block an app like Steam or Discord and Focus closes it during restricted hours.

Reads URLs via the Windows UI Automation API — no extensions, works across all major browsers
Block a full domain, a specific URL, or one YouTube channel (or just Shorts)
Process-level blocking for desktop apps
Full-screen lock on violation — resists Alt+F4, mutes audio, hides the taskbar

Daily limits

YouTube 60 min. Instagram 30. Netflix weekends only.

Give any app or website a daily time budget. Focus tracks usage in real time and blocks it for the rest of the day when the budget runs out — then resets at midnight. Every day of the week can have its own limit: strict on weekdays, relaxed on weekends.

Per-app, per-website daily limits with a separate value for each weekday
Group several apps into one shared budget (e.g. "Social: 45 min/day")
Built-in for YouTube, Shorts, Instagram, TikTok, Facebook, Netflix, Reddit and more — add unlimited custom apps
Watch remaining minutes count down live on the dashboard

Downtime & Free Time

Hard-block everything from 9 pm to 7 am.

Downtime is a hard stop: during your scheduled window every app and site is blocked. Free Time carves out the exceptions — whitelist a meditation app, a reading app or a calculator so they stay open even during downtime.

1 downtime window free; up to 4 windows on Pro for multiple cut-offs a day
Up to 4 Free Time windows that punch holes in downtime
Windows wrap past midnight and re-check on the wall clock
Sort every app and site into Productive / Neutral / Unproductive for cleaner reports

Usage tracking & reports

Know exactly where your hours went.

Focus quietly logs every app and website. The activity timeline breaks your day into 30-minute bars, and usage summaries roll up active vs idle time, YouTube, Shorts and rules broken — so the picture is impossible to argue with.

Activity timeline at 30-minute resolution, with active-vs-idle detection
Optional periodic screenshots — visual proof, kept on-device, admin-only to delete
Daily / weekly / monthly email reports with charts (Pro)
Attach screenshots to reports for parents or managers (Pro)

One app, three jobs

For yourself, your kids, or your team.

One admin holds a 4-digit PIN; rules apply to any number of user accounts. Built for real families after every cloud-based alternative fell short — lightweight, local-only, and granular enough to block a single channel.

Yourself

Be your own admin. Set up your restrictions, lock them behind a PIN, and trust your future self not to know it. Great for solo deep work.

Your family

Each child gets their own rules, timeline and limits. Pause requests can flow to you for one-click email approval — no shared password.

Your team

Set minimum working hours, define tracked hours, and get reports. Accountability for small in-house or remote teams, without per-seat cloud fees.

Fully offline · 100% private

Your data never leaves your PC. Period.

Focus watches every app and website and how long each is used — but none of it is ever sent anywhere. Everything is stored locally on your device. No tracking, no ads, no model-training on your activity. Rules that hold, too: closing the window doesn't stop enforcement, a watchdog restarts Focus if it's killed, and settings stay locked behind the admin PIN.

FAQ

Common questions

Does Focus need admin rights?

Day to day, no — Focus runs under your regular Windows user account and reads browser URLs with the Windows UI Automation API, which doesn't require elevation. Installing and uninstalling do need Windows admin rights.

Which browsers does it block?

All major browsers — Chrome, Edge, Firefox, Brave, Opera, Vivaldi, Internet Explorer, Maxthon, LibreWolf and Waterfox. Focus reads the active URL from each browser via the Windows UI Automation API, so there are no extensions to install and no browser-hopping loophole.

Can it really block just one YouTube channel?

Yes. Block one channel and the rest of YouTube keeps working, or block YouTube Shorts on its own while leaving regular videos alone. You can block a full domain, a specific URL, or an individual YouTube channel.

Can my kid just uninstall Focus or close the window?

Closing the window does nothing — Focus keeps running and enforcing rules in the background, and a watchdog restarts it if it's killed. Settings are locked behind a 4-digit admin PIN, and uninstalling requires Windows admin rights, so a standard user account can't simply remove it.

Does it work offline?

Blocking, limits, downtime, screenshots and activity tracking all work offline, and all your data stays on your device in a local database. Only email reports and license activation need internet.

How is it different from a browser extension blocker?

Browser extensions only work inside the one browser they're installed in — open a different browser and you're free. Focus reads URLs from every supported browser and enforces blocks at the process level for desktop apps. No extensions, no browser-hopping loophole.

Can I get a refund?

Try the free version first — it includes website and app blocking and screenshot monitoring, enough to see if Focus fits your setup. If you purchase and it's not right, within 3 days it's a no-questions-asked full refund. Email [email protected] with your order details.
