Stuon — Focus Timer & Site Blocker

Start Stuon focus sessions from any tab and block distracting sites. Every session syncs to your Stuon heatmap.

Stuon is a study timer for Chrome. Start a focus session from any tab, block the sites that pull you away, and keep every minute on your study heatmap at stuon.space. Install it if you want a study timer that is already in the browser when you sit down to work. The session you start here is the same study timer as on stuon.space, so the time counts toward your heatmap and study history. What this study timer does? • Start, pause, and stop a study timer without leaving your current page. • Choose a countdown, a Pomodoro study timer, or a stopwatch. • Name what you are studying. Finished sessions sync to your Stuon account. • Block distracting sites during a focus session, all the time, or with Strict mode. • Strict mode asks for your password, repeated confirmation, and the phrase "I'm giving up" before a blocked site opens. Why install it A study timer helps only if starting it is easy. Stuon sits in the Chrome toolbar, so a session is one click away. Site blocking keeps that study timer honest: the pages you chose stay closed while you study. When you stop, the minutes are saved on stuon.space, next to your heatmap and the rest of your study tools. Your account lives on the web Create an account and review your study history at https://stuon.space. The extension connects to that account. It does not keep a separate timer. Who it is for Students who want a simple study timer, a Pomodoro study timer, or a site blocker tied to the time they already track on stuon.space.
