Focus Blocker

A premium Pomodoro timer & hard-locked cognitive pre-commitment site blocker by Zivor Global.

Focus Blocker — Pomodoro Timer & Hard-Lock Site Blocker | by Zivor Global Stop negotiating with yourself. Lock in. Get it done. Most productivity extensions have one fatal flaw — you can bypass them the moment willpower runs out. Focus Blocker is different. Built on the science of cognitive pre-commitment, it removes the option to cheat. Once a focus session starts, distracting websites are hard-locked — no override, no escape hatch, no "just five more minutes." This is not a gentle reminder app. This is a commitment device. 🔒 WHAT IS HARD-LOCK BLOCKING? Regular site blockers let you disable them mid-session. That defeats the entire purpose. Focus Blocker uses hard-lock technology — once you commit to a focus session, blocked sites cannot be accessed until the session ends. No pause button. No disable toggle. No workaround. You made a commitment before the session started. Focus Blocker holds you to it. This is the psychology of pre-commitment — a Nobel Prize-winning behavioral economics principle that says the best way to resist temptation is to eliminate the choice entirely. When the option to quit doesn't exist, you don't quit. 🍅 BUILT-IN POMODORO TIMER — THE WORLD'S MOST PROVEN FOCUS SYSTEM The Pomodoro Technique has helped millions of students, developers, writers, designers, and professionals achieve more in less time. Focus Blocker integrates a fully-featured Pomodoro timer directly with the hard-lock blocker so both work as one system. How it works: Set your Pomodoro session (default: 25 minutes work / 5 minutes break) Add the websites that steal your focus — social media, news, video streaming, anything Start the session — sites are instantly hard-locked Work without distraction until your break Take your break, then start the next round Work in focused bursts. Rest on schedule. Repeat. That's the formula behind elite productivity. 🧠 THE COGNITIVE PRE-COMMITMENT EDGE Most people fail at focus not because they lack discipline — but because they keep re-making the decision to stay focused every few minutes. Every temptation to open Instagram or check Twitter is a new decision point. Willpower is finite. It runs out. Pre-commitment removes decision fatigue from the equation. You decide once — before the session — that you will focus. Focus Blocker enforces that decision automatically. You stop fighting yourself and start working. This is the same principle used by elite athletes, top CEOs, bestselling authors, and behavioral economists to guarantee performance even when motivation dips. ⚡ KEY FEATURES ✅ Hard-Lock Site Blocking — Blocked sites stay blocked for the entire session.

Focus Blocker doesn't. ❌ Other extensions charge monthly subscriptions for basic blocking features. Focus Blocker is free. ❌ Other extensions track your browsing history and sell behavioral data. Focus Blocker collects nothing. ❌ Other extensions are either a timer or a blocker. Focus Blocker combines both in a single unified pre-commitment system. The question isn't whether you should block distractions. The question is whether your blocker actually holds you accountable when it matters most. Only hard-lock blocking does that. 📖 THE SCIENCE BEHIND FOCUS BLOCKER Focus Blocker is built on three pillars of behavioral and cognitive science: 1. Pre-Commitment Theory (Thaler & Ariely) — Behavioral economics shows that people make better decisions when they bind themselves to choices in advance. Pre-commitment works because it eliminates the temptation to renegotiate with yourself in moments of weakness. 2. The Pomodoro Technique (Francesco Cirillo) — Time-boxed work intervals with scheduled breaks reduce cognitive fatigue, combat Parkinson's Law, and improve focus quality. Decades of real-world use across millions of professionals validate its effectiveness. 3. Decision Fatigue Research — Every choice you make throughout the day depletes your mental energy. By automating the decision to stay focused, Focus Blocker preserves your cognitive resources for the work that actually matters. 🔐 PRIVACY & PERMISSIONS Focus Blocker requests only the permissions required to function: Block websites during sessions — This is the core function. Nothing more. Focus Blocker does not read your browsing history. It does not collect personal data. It does not sync to external servers. It does not require account creation. Your focus is private. Your data stays yours. 🏢 ABOUT ZIVOR GLOBAL Focus Blocker is published by Zivor Global — a product-focused company building practical, no-nonsense tools that solve real problems for real people.
