Pomodoro Timer

What is a Pomodoro timer?

A Pomodoro timer splits work into 25-minute focus blocks with 5-minute breaks, using a fixed rhythm to beat procrastination and mental fatigue. This one runs entirely in your browser — no account, no server, nothing to install.

How this timer works

• Set focus and break lengths (25 and 5 minutes by default).
• Start the timer — it counts down the focus block, then flips to a break automatically.
• Pause and reset controls let you adjust on the fly.
• Completed focus sessions are saved to your local history.

How to use the result

1. Work through one focus block with distractions off — phone face-down, notifications silenced.
2. Take the short break fully — stand, stretch, look away from the screen.
3. After four focus blocks, take a longer break (15–30 minutes) — that’s the classic cycle.
4. Track how many blocks a task actually takes, then estimate better next time.

Does the Pomodoro technique actually work?

For many people, yes — not because 25 minutes is magical, but because it forces commitment in small, winnable chunks and makes starting easier. That’s exactly what procrastination blocks: the act of beginning. The timer is a scaffold, not a strict rule — adapt block length to your focus span.

Common mistakes

• Checking notifications during a block. The break is when you check — the focus block is the point.
• Extending the block indefinitely. If you’re flowing, keep going — but don’t skip breaks habitually, they’re what sustains the rhythm.
• Timing busywork. Pomodoro works on meaningful chunks; email-refresh sprints just burn blocks.

Focus is a resource you manage — the same way the sleep cycle calculator schedules rest and the water intake calculator schedules hydration. Run a block, take a break, repeat.
