To be the BEST web timer.
Track the browsing time, running time and visits of each website on your browser.
With Timer, you can:
✅ See browsing time, running time of today, or this week, or this month in the popup page.
✅ See all data rows, which can be merged by subdomains or by date.
✅ See the daily trend of time you spent on any site.
✅ See your surfing habits at different times everyday.
And some additional features:
✅ Support one whitelist to exclude sites you don't want to count.
✅ Support to manually set the rule of domain merge.
✅ Support to set daily limit of each site.
Also promise that all data is stored in Chrome Local Storage, and not send it anywhere. Also, you can backup them by yourself with Github Gist.
