OmniCalcsPomodoro Timer
Work in focused 25-minute blocks with short breaks — a proven technique for deep productivity.
The Pomodoro Technique
- Pick one task and commit to a single 25-minute work block.
- Take the short break — stretch, walk, look away from screens.
- After 4 blocks, enjoy the long break. Then start the next cycle.
- Adjust the block length to match your concentration span.
Frequently Asked Questions
Does the timer keep running in the background?
It uses the system clock, so it stays accurate even in background tabs, though updates may be throttled by the browser.
Why 25 minutes?
Long enough to make progress, short enough to stay focused. If 25 is too short or long, adjust the work field.
What counts as a completed pomodoro?
One uninterrupted work block. If you get distracted, reset the block and start over — that's the rule.
Are the settings saved?
No — every session starts fresh. Nothing is stored or sent anywhere.
Practical Example
With the default settings — 25-minute work, 5-minute short break, 15-minute long break every 4 sessions — one full cycle of four pomodoros is 4 × 25 = 100 minutes of focused work plus 3 × 5 = 15 minutes of short breaks, finishing with a 15-minute long break. That is 130 minutes, or 2 hours 10 minutes, from the first Start to the end of the long break.
- Adjust the work field to 50 and the sessions field to 2 for a "deep work" variant of the same rhythm.
