Pomodoro Timer
Focus with automatic Pomodoro work/break cycles.
Work
25:00
Completed work sessions: 0 · Status: Idle
Pomodoro Timer runs the classic focus technique—alternating work sessions with short and long breaks—directly in your browser. Use the 25/5/15 preset or fully customize durations to match your own workflow.
How it works
Pick the classic preset or set custom work, short break, and long break minutes plus how many work sessions occur before a long break. Click Start to begin the work phase; when it ends, the timer automatically switches to a break, and back again, until you pause or reset.
Benefits
- Classic 25/5/15 preset or fully custom durations
- Automatic phase transitions between work and breaks
- Pause and resume without losing progress
- Tracks completed work sessions toward your long break
Use cases
- Structure focused work blocks with built-in breaks
- Study in timed intervals to reduce burnout
- Time-box deep work sessions during a workday
- Build a consistent focus habit with repeatable cycles
Best practices
- Fully commit to the work phase and save breaks for the break phase
- Use the long break after several cycles to properly recharge
- Adjust durations to match your task—longer for deep work, shorter for quick sprints
- Reset between unrelated work sessions to start a clean cycle count
Common mistakes
- Changing durations mid-session and expecting the current phase to resize
- Skipping breaks entirely, which defeats the purpose of the technique
- Setting cycles before long break to 0, which is not a valid value
- Assuming the timer sends a sound or notification when a phase ends

Frequently asked questions
- What is the classic Pomodoro schedule?
- The classic technique uses 25 minutes of focused work, a 5-minute short break, and a longer 15-minute break after every 4 work sessions. You can load this as a preset or customize every value.
- Does the timer automatically switch between work and break?
- Yes. When a phase finishes, the timer automatically advances to the next phase (work, short break, or long break) and keeps counting down without manual restarts.
- Can I customize the work and break durations?
- Yes. Set custom minutes for work sessions, short breaks, and long breaks, plus how many work sessions occur before a long break, from 1 to 180 minutes each.
- Can I pause a session and resume later?
- Yes. Click Pause to stop the current phase's countdown, then Start again to resume from the exact remaining time without losing progress.
- How does the long break cycle count work?
- After completing the number of work sessions you set (4 by default), the next break becomes a long break instead of a short one, then the cycle count resets.
- Is my Pomodoro session data saved anywhere?
- No. The timer runs entirely in your browser's memory. ToolHub does not receive, log, or store your session settings or history.
