LockIn

Pomodoro focus timer with intelligent website blocking. Stay locked in.

You open your laptop to start working. Forty-seven minutes later you're watching a video about how concrete is made. LockIn fixes that. Start a focus session and anything not on your allowlist gets blocked — immediately. No loopholes, no "just one quick check." When the session ends, you're notified and your break begins automatically. Then you go again. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⏱ Pomodoro Timer Classic 25/5 setup or custom sessions up to 120 minutes. Common presets like 50/10 and 90/20 included. 🔒 Website Blocking Blocking starts the moment your session does. You choose your allowlist — everything else is locked out until the session ends. 🔔 Session Notifications A small nudge when focus ends and break begins, and again when it's time to get back to work. 📊 Activity Heatmap A GitHub-style graph of your past 12 weeks. See your consistency at a glance. 🏆 Points & Streaks Earn points per session and maintain daily streaks. Simple motivation that adds up. 🌗 Dark & Light Mode Switch anytime. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ → Developers who open social media "for a minute" and lose half an hour → Students trying to finish assignments without constant distractions → Writers who need uninterrupted time to actually write → Anyone who knows what they need to do — but can't stop opening new tabs ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Everything stays in your browser. Settings, stats, allowed sites, and session history are stored locally using Chrome's built-in storage. Nothing is collected. Nothing is sent anywhere. Permissions used: tabs & webNavigation — to block distracting sites scripting — to show session notifications alarms — to keep the timer accurate even if the popup is closed ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ No account. No subscription. No tracking. Lock in and get back to focusing.
