Deep Focus

Deep Focus is a website blocker and Pomodoro focus timer built on one idea: friction beats willpower. Start a session and every tab that isn't on your whitelist is closed — not just blocked, closed — until your time is up. Want out early? That takes a deliberate 2½-minute wait*, not a click. No "just checking one thing." No five-second detour that swallows an hour. Just you and your work. This is built for students cramming for exams, writers, developers, researchers, founders — anyone who does real deep work and needs pure focus. Sessions default to a 25-minute lockdown that ends in a 5-minute wind-down (customisable, of course), tuned to primacy and recency — how memory actually works: you retain more at the start and end of a session than in the middle; so short, intentional, regular bouts beat marathon "focus" sessions that quietly become distraction sessions. What you get: • Whitelist-only browsing during sessions — you decide what stays open • Force-closed distracting tabs, with a real wait to undo it • Close the tab during the unlock countdown and the timer resets. Breaking focus has to be a choice, not a reflex. • Customisable Pomodoro timer, adjustable to your rhythm • An insights dashboard — today, week, month, year, lifetime • Free forever for the core blocker. Pro unlocks deeper customisation — adjustable friction timers, whitelist workspaces, greyscale during sessions, unlock counts, notification styles and a colour dashboard theme — as a one-time £1.99 purchase, not a subscription. Built for exam season, deep work, and anyone who's tried "just being disciplined" and wants something that actually holds the line. This is completely free to install and you can always uninstall later — so it's worth a try. *One emergency unlock is available per week, for when you genuinely need it. ━━━━━━━━━━━━━━━━━━━━━━ 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: • Only the sites you explicitly allow are reachable during a session. Adding a new one mid-session requires a 2½-minute wait — 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 wind-down (default 25 minutes, the last 5 a wind-down reminder — fully customisable). Browsing stays locked until the very end. • 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-minute block, with its 5-minute wind-down, 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 long-term growth 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. • Lock Settings during a session, so the whitelist can't be touched until the block ends. ━━━━━━━━━━━━━━━━━━━━━━ 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. • Whitelist workspaces — separate sets of allowed sites for different kinds of work, swapped in one click. • Greyscale during sessions — even your whitelisted sites go grey until the block ends. • Add time mid-session (+1m / +5m) — time can only be added, never taken off. • Choose how many emergency unlocks you get each week. • Block backups during a session, so exporting one can't become the way out. • Timer-end notification styles and a full-colour dashboard theme (it's monochrome by default). Pro is a one-time £1.99 purchase, not a subscription. ━━━━━━━━━━━━━━━━━━━━━━ 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 binds your licence and is verified periodically with healthevate.com. Opening Settings also checks that email with healthevate.com for a licence you already own, so Pro switches itself on on a new device; if there isn't one, nothing is stored. That's it.
