15/5 Pomodoro timer
15 min focus, 5 min break, then a 15 min long break after 4 sessions. 1 hr 30 min total.
What this one is for
The 15/5 timer makes the first work commitment smaller than a standard 25-minute block. It is useful when you want to try a limited piece of a task before planning a longer session.
Four 15-minute focus periods provide sixty minutes of work. Three five-minute breaks and one final fifteen-minute break bring the full cycle to ninety minutes.
Choose a concrete first task, such as outlining one paragraph or sorting one folder. This is an optional schedule, not a clinical recommendation or a rule about attention spans. Change the duration if it does not fit.
Good for
- Starting one small, defined task
- A short practice block
- Tidying one area with a clear ending
How it runs
15 min focus, 5 min break, then a 15 min long break after 4 sessions. 1 hr 30 min total. Press Start, or hit Space. The phase word and icon above the progress bar tell you where you are.
Check the Sound chip and device volume before starting. Work and rest have different tones. The tab title shows the time left. Start begins the first phase immediately; prepare your space first.
Keep the page visible for cues. The timer requests an awake screen, but the browser can refuse it or delay background sound. For offline use, load this exact page online and test a reload without a connection before relying on it.
Change the settings before starting. Durations use minutes. This page opens with its preset each visit; the main timer page remembers your valid settings.
Common questions
Is fifteen minutes long enough to get anything done?
Yes, for lots of tasks. A finished fifteen minutes beats an unfinished fifty. It also gets you started, which is often the hardest part.
How do I grow the blocks over time?
Once fifteen minutes feels easy, move to 20, then 25. The breaks can stay at five. On the main Pomodoro timer, your numbers are saved in your browser, so the new length sticks.
Can I make the cycle shorter?
Yes. Reduce Focus sessions. With one session, you get fifteen minutes of focus followed by the configured long break.
Can I use it without setting anything up?
Yes. Press Start or Space and the 15/5 pattern runs as it is. There’s no account, nothing to install, and it can work offline after its required files are cached; test an offline reload first.
