ScrollSense - Attention Tracker & Time Heatmap

Measure real attention per site — engaged time vs passive open-tab time.

Know where your focus actually went. Most time trackers lie to you. They count every second a tab is open — whether you were reading, working, or just forgot to close it. ScrollSense is different. It separates the time you were actively engaged with a site from the time it was merely sitting open in the background, giving you an honest picture of where your attention really goes. WHAT IT DOES ScrollSense runs quietly in the background, tracking two distinct signals for every site you visit: 🟢 Active Time — seconds where you were genuinely present: scrolling, clicking, typing, reading. 🔵 Idle Time — seconds the tab was open but you weren't doing anything. The difference between these two numbers is your real attention score. KEY FEATURES Live Status Indicator A real-time pill in the popup shows your current site, whether your session is Active or Idle, and a per-site attention ratio for today — updated every few seconds. Daily Summary See today's top domains ranked by active time, with a dual bar showing the active/idle split at a glance. Know instantly which sites earned your focus and which ones just hoarded your tabs. Weekly Attention Heatmap A 7-day × 24-hour heatmap shows exactly when during the week you were most engaged online. Spot your peak focus hours, your distraction patterns, and your late-night tab-hoarding habits — all in one view. Privacy-First, Local Only Zero accounts. Zero cloud sync. Zero telemetry.
