Deep Focus

Block distracting sites and force-close off-limits tabs for timed study and deep-work sessions. Built on intentional friction.

Deep Focus turns your browser into a distraction-free workspace. Start a session and every tab that isn't on your whitelist is closed — and stays closed — until your time is up. No "just checking one thing." No five-second detour that swallows an hour. Just you and the work. Built for students cramming for exams and for anyone who does real deep work: writers, developers, researchers, founders. ━━━━━━━━━━━━━━━━━━━━━━ WHY IT WORKS: INTENTIONAL FRICTION ━━━━━━━━━━━━━━━━━━━━━━ Most blockers fail because they're one click to switch off. Deep Focus is built around deliberate friction, so the easy path is to keep working: • Whitelist-only browsing. Only the sites you explicitly allow are reachable. Everything else is blocked for the whole session. • A 2½-minute wait to add a new site or stop early. If you genuinely need it, the wait costs you nothing. If the impulse is just a craving, it fades before the timer ends. • One emergency unlock per week. A real escape hatch for real emergencies — not an everyday off switch. • Close the tab during the unlock countdown and the timer resets. Breaking focus has to be a choice, not a reflex. ━━━━━━━━━━━━━━━━━━━━━━ THE FOCUS TIMER ━━━━━━━━━━━━━━━━━━━━━━ • Time-boxed deep-work blocks with a built-in rest period (default 25 minutes focus + 5 minutes rest — a clean half-hour you can fully customise). • A calm countdown, progress bar and toolbar icon that shifts colour when it's time to rest and when you're done. • Schedule sessions to auto-start at set times on the days you choose — build a routine that runs itself. • Optional end-of-session alerts: a chime, a green toolbar icon, or a full break / completion page. ━━━━━━━━━━━━━━━━━━━━━━ THE SCIENCE ━━━━━━━━━━━━━━━━━━━━━━ The default 25 + 5 split is built around primacy and recency — you remember more from the start and end of a study block, and the long middle is where attention sags. Shorter, focused bouts mean more high-retention "starts" and "ends" and less dead time. Tune the lengths to whatever keeps you sharp. ━━━━━━━━━━━━━━━━━━━━━━ SEE YOUR PROGRESS ━━━━━━━━━━━━━━━━━━━━━━ A full insights dashboard turns discipline into momentum: • Daily, weekly, monthly, yearly and lifetime views. • Goal rings, hourly heatmaps, session timelines and a GitHub-style contribution map. • Streaks that reward showing up day after day. • XP and 10 levels, from Beginner to Transcendent, with 25 achievements to unlock. • Personal insights — your most productive hour, your best day of the week, week-over-week trends. Your focus history stays on your device and syncs through your own browser account. It is never sold or shared. ━━━━━━━━━━━━━━━━━━━━━━ SERIOUS-MODE OPTIONS ━━━━━━━━━━━━━━━━━━━━━━ • Unstoppable Mode — removes the stop button entirely for the session. • Strict Whitelisting — no new exceptions can be added once a session is running. • Enforce Incognito — pauses focus if the extension is disabled in private windows, closing a common bypass. • Block the extensions page during a session, so turning Deep Focus off takes real effort. ━━━━━━━━━━━━━━━━━━━━━━ DEEP FOCUS PRO (optional upgrade) ━━━━━━━━━━━━━━━━━━━━━━ Everything above is free. Pro is for people who want to dial in the friction: • Configurable friction timers — set every wait from 10 seconds to 10 minutes. • Adjust the timer mid-session (+/− minutes on the fly). • Choose how many emergency unlocks you get each week. • Timer-end notification styles and a monochrome dashboard theme. ━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━ Deep Focus checks the sites you visit only on your own device to decide what to block — your browsing history is never collected or transmitted. If you buy Pro, your browser-profile email is used once to bind your licence and is verified periodically with healthevate.com. That's it.
