I built a Chrome extension that shows exactly how long you've been on any tab — Tab Timer
I just published Tab Timer on the Chrome Web Store and wanted to share it here.
What it does:
Tab Timer tracks how much time you spend on specific websites and shows a small floating widget directly on the page — so you always know how long you've been on a tab without opening anything extra.
Key features:
- Floating on-page widget — draggable, 4 size options, shows the live timer right on the page
- Focus Mode — only the active tab's timer runs; all others pause when you switch tabs
- Lock timers — page refreshes won't reset your count
- Per-site control — enable tracking only on the sites you care about, or turn it on for all sites
- Analytics — view time trends, top sites, and daily breakdowns (stored locally, nothing leaves your device)
- Pause, resume, and reset per tab from the popup or the widget
Why I built it:
I kept losing track of how long I'd been on certain tabs — research sessions, YouTube rabbit holes, work dashboards. Browser history doesn't tell you duration. Tab Timer fills that gap without being intrusive.
Privacy: No data ever leaves your device. Everything is stored in Chrome's local storage only.
Would love any feedback, bug reports, or feature suggestions. Happy to answer questions in the comments!
