Pomodoro timer

What is the Pomodoro Technique?

The Pomodoro Technique repeats 25 minutes of focus → 5 minutes of break, with a longer 15–30 minute break after every four cycles. The short deadline helps you focus and the regular breaks keep fatigue down.

• Work on one thing during a focus block.
• Look away from the screen and move during breaks.
• Focus, break and cycle counts are all adjustable (for example 50/10).

Pulsar Timer moves to the next phase automatically and notifies you each time.

How to use

1. Type a time — 25 (minutes), 5:00, 1h30m or 90s, then press Enter or Start.
2. Run several at once — every start adds another card. Noodles for 3 minutes, laundry for 40 and a meeting for 25, all on one screen.
3. Presets — save times you use often and start them with one click.
4. Works from other tabs — the tab title and icon show the time left, and you get a notification and a sound when a timer ends (turn notifications on in ⚙ Settings).
5. Alarms & mini window — ⏰ opens time-of-day alarms, and ⧉ (while a timer runs) opens an always-on-top mini window.

Offline & privacy

Pulsar Timer runs entirely in your browser with no server. Timers and presets are stored only in this device's browser storage (localStorage) and are never sent anywhere. After the first visit it works offline, and running timers keep going across reloads and reopened tabs because each one tracks its target time.

Focus mode — a fullscreen timer

Press the focus mode icon on a running card (or F) and everything else disappears: only that timer's time left, huge, in the middle of the screen. It is a fullscreen timer and focus timer for studying, talks or workouts when the clock is all you want to see.

• Where supported it opens fullscreen and keeps the screen awake (Screen Wake Lock).
• Leave the mouse still and the cursor and buttons hide; move it to briefly show pause, color background and exit.
• Pomodoros show the focus/break phase and roll into the next phase automatically.
• Press Esc to leave. When time is up the screen pulses with the end sound, and you can choose Again or Close.

Keep a timer always on top in Chrome & Edge

While a timer is running, press ⧉ Pop out — always on top to open a small timer window that floats above every other app and window. It is an always on top timer that stays visible while you write, sit in a meeting or play. The ⧉ button next to Start starts a timer and pops it out in one click.

Resize the mini window and the digits scale with it; several timers stack vertically. This uses Document Picture-in-Picture, so it appears only in Chrome and Edge 116+; Firefox and Safari do not show the button.
