FocusLens is the free, privacy-first Chrome productivity tracker that quietly watches every tab, categorizes your day, blocks distracting websites on demand, and helps you hit daily focus goals. Zero signup. Zero servers. 100% yours.
Most of us are strangers to our own calendars. We answer "where did today go?" with a shrug and a suspicion that maybe a lot of it went to a feed.
Screen time reports from your phone don't help — the real thief is the tab you opened "just for a second" while working. The pull-to-refresh muscle memory. The seven YouTube tangents between one Stack Overflow answer and the next.
FocusLens puts a clean, honest receipt in front of you every evening. No judgment — just a chart, your hours, and the data to decide what needs to change.
It runs quietly in the background, respects your privacy with local-only storage, and gives you the one thing every other "productivity app" asks you to pay for: truth.
A complete browser-based time tracker and focus tool. Automatic website tracking, smart categorization, distraction blocking, daily goals, and streak tracking — all bundled into one free Chrome extension.
FocusLens quietly records how long you spend on every website, bucketed hour-by-hour. Works out of the box — no rules to set, no timers to start. Smart idle detection pauses tracking when you walk away, so your numbers are real.
Works with: Chrome, Brave, Edge, Opera, Arc, Vivaldi — any Chromium browser.
Sites are auto-grouped into Productivity, AI, Social, Entertainment, News, and Shopping. Built-in recognition for GitHub, Claude, Figma, Notion, YouTube, Twitter/X, Reddit, Netflix and hundreds more.
One-click distraction blocker. List the sites that kill your focus and Focus Mode replaces them with a calm motivational page. Toggle on for deep work, off when you want to scroll.
Set a productive-time target (default 4 hours) and watch the streak badge climb. Duolingo-style gamification that nudges you without nagging.
Hourly chart for today, 7-day rollup for the week, all-time top-sites leaderboard for the long view. Every slice you'd want, nothing you wouldn't.
Step away for coffee and tracking pauses automatically. Your "2 hours on Google Docs" actually means 2 hours — not "2 hours with a tab open."
Every row of data is yours, exportable any time. Slice it in Excel, feed it into a script, back it up — FocusLens doesn't hold it hostage.
Running a freelance shop? Add a "Client work" bucket. Learning Spanish? Tag Duolingo and YouTube Spanish lessons together. Pick the color, add the domains, done.
A small ping when you hit your daily goal. That's it. No pop-ups every 20 minutes, no guilt-trips, no streak-breaking panic at 11:57 PM.
No account. No OAuth dance. No "which workspace" picker. Install, pin, browse — that's the flow.
Download the zip, drop it into chrome://extensions as an unpacked extension. Takes 30 seconds.
Pin the icon for one-click access. FocusLens starts tracking in the background — nothing to configure.
Just work. FocusLens silently records every site, every hour, every day. Idle detection pauses when you step away.
Click the icon any time to see the receipts. Set a goal, blocklist a distraction, hit your streak. Iterate.
Whether you're managing sprints, writing dissertations, running a startup, or just tired of losing afternoons to Reddit — here's how real people use FocusLens.
Prove your deep work hours to yourself (and, if you need to, anyone else). Spot the afternoon slump before it eats a week.
Log study time that's actually study time. Tag textbook sites, academic journals, and learning platforms into a "Study" bucket.
Stop guessing when you log client hours. Custom categories per client let you see exactly where each invoice came from.
You can't scale what you don't measure. See if your "building" week was actually building, or just researching competitors on Product Hunt.
Most "free" productivity trackers are free because you're the product. FocusLens is different. There's no server to send data to — we don't have one. The extension writes to Chrome's local storage and that's where your data lives and dies.
An honest side-by-side with the most popular productivity and time-tracking tools. We're not better at everything — but we're clearly better for people who want a free, private, browser-first solution.

Still curious? The short answer is "yes, it's free, and no, we don't collect anything." But here are the longer answers.
chrome.storage.local API. There's no backend, no analytics, no telemetry, no third-party scripts. When you uninstall the extension, Chrome purges the data automatically. We literally have no way of knowing you use the product.
chrome://extensions, toggle "Developer mode" on in the top right, click "Load unpacked", and select the focuslens folder. Pin the icon to your toolbar and you're set. The whole thing takes under a minute.
Install FocusLens in under a minute. Start getting honest data about where your browser hours go — and build the habit of actually doing something about it.
