Time Ward by Vipwin

Time Ward helps you keep your attention where it matters. Start a focus session and the sites on your blocklist won’t open so you can stay on task. If certain pages tend to eat time, set a daily limit for them and the extension will quietly count only the minutes you spend with that page visible, then block the rest of the day when you reach the limit. You can add the current site with one click, set a timer for short sprints or longer sessions, and review usage for limited sites right in the popup. Everything runs locally in your browser. There are no accounts and no data leaves your device.
