Attention Span & Screen Time Tracker - Focus Score, Site Blocker

Screen time tracker that measures your real attention span. Block distracting sites, set daily limits. Private, all on-device.

Most screen time trackers tell you that you spent four hours on YouTube. This one tells you why that happened. Attention is a screen time tracker that measures your attention span - the median unbroken stretch you actually manage on a single site before switching away. Then it gives you real tools to block distracting websites and get that number back up. WHAT MAKES THIS DIFFERENT Every other website usage tracker reports totals. Totals hide the problem. Four hours in one focused block and four hours split across two hundred tab switches look identical on a pie chart, but they are not the same day. Attention measures the shape of your focus: • Attention span - your typical unbroken stretch on one site • Longest focus - the best run you managed all week • Switches per hour - how fragmented the day really was • Rabbit holes - chains of four or more different sites with no pause between them • Deep focus share - how much of your time was in sessions over five minutes Nothing else in the Chrome Web Store measures this. SCREEN TIME TRACKING THAT IS ACTUALLY ACCURATE • Per-site screen time, updated live • Idle time excluded automatically - walk away from the keyboard and the clock stops • Only the active, focused tab is counted, so background tabs never inflate your numbers • Sleep and browser restarts are handled, so a closed laptop never becomes eight hours of screen time Most trackers get at least one of these wrong. It is the difference between data you trust and data you ignore. A DAILY FOCUS SCORE, 0 TO 100 One number for how the day went - a simple productivity score built from how your time split across categories and how concentrated it was. Sites are sorted automatically into Work, Learning, News, Social, Fun and Shopping - no setup, no manual tagging. See it by day, yesterday, week, month, year, or as a running total since you installed. Every period compares against the one before it, so you know whether you are improving. An hour-of-day heatmap shows when you actually browse, which is usually more revealing than what you browse. BLOCK DISTRACTING WEBSITES - LIMITS THAT ACTUALLY HOLD Set a daily time limit on any site. When you reach it, the page is replaced - not a notification you can swipe away. Every tab on that domain is blocked, so switching to your second YouTube tab does not work. Free: daily limits per site, from 15 minutes to 3 hours, with a five-minute snooze. PRO - $3.99 A YEAR • Focus sessions - a focus timer for 25, 50 or 90 minutes of blocking on demand • Recurring schedules - "block Social and Fun, weekdays 9 to 5". Rules work by category, so sites you have never visited are covered automatically • Strict Mode - removes the escape hatches. No snoozing, no ending a session early, no quietly raising a limit. Switching it off takes a delay you set in advance, while you still meant it • Unlimited history - step back through any month or any year. Free keeps 180 days • CSV export with categories, ready for a spreadsheet • Backup and restore, so a reinstall never costs you your history • Five extra themes: Midnight, Nord, Forest, Sepia and Rose PRIVATE BY DESIGN - YOUR BROWSING NEVER LEAVES THIS DEVICE No server. No analytics. No browsing history uploaded, ever. Domains, times and every statistic are computed on your own machine and stored in local browser storage. Site categorisation runs from a table bundled inside the extension, so classifying a website never makes a network request. The extension never reads the content of any page you visit - only the domain name. When you first open the extension it asks for your name and email so you can be told about updates. That is the only thing ever sent, and it is never combined with your browsing data. WHO THIS IS FOR Students who lose evenings to rabbit holes. Anyone chasing better productivity who is tired of time trackers that only produce prettier charts. Remote workers whose focus is quietly shredded by tab switching. Anyone with ADHD who already knows they are distracted and wants the number. Anyone doing a digital detox who needs a website blocker that does not fold the moment it becomes inconvenient. HONEST ABOUT WHAT IT CANNOT DO Strict Mode cannot stop you disabling or uninstalling the extension. It is a speed bump sized to outlast an impulse, not a lock, and the extension says so in its own interface rather than pretending otherwise. Install Attention and find out what your real attention span is. Most people are surprised, and not in a good way.
