An online Pomodoro timer based on the classic rhythm of 25-minute focus sessions, 5-minute short breaks, and 15-minute long breaks, with pause, reset, skip, and full-screen controls.

Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This online Pomodoro timer runs a straightforward focus-and-break cycle. Choose Focus for 25 minutes, Short Break for 5 minutes, or Long Break for 15 minutes. The display shows the remaining time as minutes and seconds, a progress bar for the selected interval, and the current focus round. These are fixed presets: there are no fields for changing session lengths, no task list, and no saved work history.
A Pomodoro is commonly used as a bounded work interval followed by a rest. Here, the first three focus rounds lead to short breaks; the fourth focus round leads to a long break. The countdown does not move through the cycle by itself. You decide when to start, pause, reset, or advance, so the timer provides pacing without deciding what task to do.
The progress bar measures elapsed time within the currently selected mode. It starts empty when you select a mode or reset, then fills as the countdown runs. It is not a measure of completed work or a daily productivity score. The round label tracks the focus cycle: it begins at round 1 and advances when you leave a break and return to Focus.
For example, complete or manually leave Focus round 1, then choose the next session to enter a Short Break. After that break, choose the next session again to return to Focus round 2. After Focus round 4, the next session is the Long Break. The numbers describe this timer's cycle, not a rule that every person or task must follow.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Select Focus, Short Break, or Long Break. Selecting a mode loads its full preset duration and stops any running countdown.
Press Start to begin. The display counts down and the progress bar shows elapsed time for that mode. Press Pause when you need to stop temporarily; starting again resumes from the remaining time.
When ready to change phases, press Next Session. From Focus it selects the appropriate break for the current round; from a break it returns to Focus and advances the round number.
Use Reset to restore the selected mode to its full duration. Use the full-screen control when you want a larger timer view; it does not change the countdown or cycle.
When the display reaches 00:00, the current countdown stops. Select Next Session yourself to continue. If you choose a phase early, Next Session still advances according to the selected phase and current round.
Use cases
See how the tool fits into real work and everyday tasks.
Choose one chapter section, problem set, or review topic before starting Focus. During a break, step away or rest your eyes; use the next focus round for a clearly defined next item. The timer does not record which material you studied.
Set a concrete target such as drafting a section or sorting a small group of messages. Pause if a real interruption needs your attention, then resume when you are ready. The round counter can help you see where you are in the current cycle, but it does not measure output.
Use a focus interval to make progress on one manageable task, such as clearing a work surface or preparing materials for tomorrow. Decide whether to stop at the interval or finish a safe, natural step before taking a break.
Q&A
Find concise answers to common questions and confusing cases.
No. Focus, Short Break, and Long Break use fixed presets of 25, 5, and 15 minutes.
No. At zero it stops. Press Next Session when you want to move to the next focus or break phase.
The timer has no sound or system notification control. Keep the page visible if you need to watch the countdown, and use a device alarm as a separate reminder for an important deadline.
The round is held in the current page session; it is not a saved history or account statistic. Refreshing or closing the page can reset the current timer state.
Notes
Review scope, result limitations, and important precautions before use.
This countdown runs in a browser page. Browsers can delay timer callbacks in inactive tabs, and device sleep or closing the page can interrupt what you see. The [Page Visibility API documentation](https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API) describes background timer throttling. Keep the page available when timing matters, and use a separate device alarm when punctual notification is important; this page does not promise a system-level alert or background operation.
Preset intervals are a convenient starting rhythm, not a universal productivity standard. A task may need an uninterrupted stretch longer than 25 minutes, while another may call for shorter steps. Adjust your actual work and rest around the task, fatigue, and urgent responsibilities rather than treating the round number as a score.
