What this tool is built for
Run a simple timer, Pomodoro session or work/rest intervals. Set rounds, pause the countdown and choose sound or notifications.
The available controls include: Simple · Pomodoro · Intervals; Work seconds · Break seconds · Rounds; Auto-start next phase · Skip phase · Keyboard shortcuts; Sound · Notifications · Full screen.
For a quick result, you can use the tool directly on this page. If you need to run an activity with other people, create an account and use the dashboard to create and manage a shared room.
How to use it
Set up only the options you need, run the tool, then review the result and history before starting another round.
Choose a simple timer, Pomodoro, intervals or rounds.
Set work and break durations in seconds and the round count.
Start the timer; pause or resume it, and test sound and notification permissions.

Where it works well
The best setup depends on whether you need a single local result or a shared activity that other people can follow.
Focus: set 25 minutes of work and a 5-minute break.
Presentation: give each speaker a five-minute countdown; the timer does not choose speakers.
Focus sessions: structure work and breaks or keep a visible time target for a group.
Classroom: choose pupils, create exercises, split groups or make turn-taking visible to everyone.
Workouts: use timed work/rest intervals and rounds for simple training sessions.
Meetings and workshops: assign order, teams, tasks or timeboxes without stopping the session to organize them manually.
How the result is produced
Browsers can throttle background tabs and restrict sounds or notifications. Allow notifications and test alerts on your device; do not rely on them for critical reminders.
Shared rooms add a controlled group workflow: the organizer can choose access rules, add participants or let them enter themselves, share a room link, and invite people by email. What participants can see or control depends on the room settings and their role.
Capabilities and limits
Use the tool for games, lessons, workshops and everyday organization. It is not intended to replace certified draws, regulated records, medical timing or other contexts that require an audited or authoritative system.
Practical tips
- Name entries clearly before starting so participants can understand the result without extra explanation.
- Check the important settings before sharing a room; viewers may not have the same controls as the organizer.
- Use history or exported results when the tool provides them instead of relying on screenshots alone.
