Make time for yourself

A 90 minute timer for deep work

Ninety minutes is long enough to become properly absorbed in something hard. Use it for the work that needs all of your attention: a difficult chapter, a design problem, a long piece of writing.

Prepare before you start

A long block is easier when the small decisions are made in advance. Write down the one outcome you want, gather what you need, and put your phone somewhere out of reach. Fill your water glass. If you need a reference you do not have, note it and keep going rather than leaving to look.

Pace yourself inside the block

You do not have to work at the same intensity for all ninety minutes. You might warm up with the easier parts, spend the middle on the hardest problem, and use the last stretch to tidy up and note next steps. Pause if you need to; the remaining time waits for you.

Rest properly afterwards

This page sets a ten-minute short break and a twenty-minute long break. After ninety minutes, take the break away from the screen. If you plan more than one block, open Custom and lengthen the short break. Save the 90-minute rhythm with your room and sound mix as a session so the next block starts in one click.

A few useful details

How do I start a 90 minute timer?

A fresh timer on this page is set to 90:00 and starts when you press Start focusing. If you already have a running or paused timer, it is kept; use the new-timer button and confirm to replace it.

Will sound play for the whole ninety minutes?

It should, as long as the tab stays open and the device stays awake. A phone may pause audio when the screen locks, so turn on Keep screen on where supported, or use a laptop that is plugged in.

Does the timer drift over a long session?

No. It keeps time against a fixed end point, even in a background tab.

Can I add sound to a 90 minute session?

Yes. Rain, fireplace, ocean, instrumental music and white, pink or brown noise each have their own volume slider. For a long block, a steady layer such as brown noise or rain is easy to leave running in the background.

Find your rhythm.

A little structure, on your terms.
Choose a rhythm or make it your own.

Use whole minutes from 1 to 180. Take a long break after every four completed focuses. Each new phase waits for you to start it.

Changes apply to your next timer. A running or paused timer keeps its current duration.

How your timer works

Your timer and preferences stay in this browser. The countdown catches up after sleep; a backwards clock change pauses it. Completion sounds may be delayed or silenced while your device sleeps. Enable the chime in Sounds.

Timer & preferences

The chime has its own soft volume. Your device may silence it while asleep. Rain starts when you enter Night Rain or Darling Harbour. Layer sounds here or pause them individually. Audio gently softens at the end of a focus phase.
