90/10 Pomodoro

90/10 is 90 minutes of focus and a quick 10-minute break. It has the fewest interruptions of all the rhythms and is meant for people who already focus well.

▶ Start a 90/10 timer

Focus + break: 90 min + 10 min
In 3 hours: 170 min of focus
Best for: Long uninterrupted flow

What it is

Ninety minutes is a popular length for deep work. The short 10-minute break keeps you close to the task, so you stay in the zone instead of fully switching off. It suits flow-heavy work, but it asks a lot, so build up to it.

How it works

01Clear distractions, choose a single outcome and start with the hardest part.
02Set the timer for 90 minutes and work on that one thing only. If another idea pops up, write it down and keep going.
03When the bell rings, stop and take 10 minutes away from the screen.
04Repeat, and after a few rounds take a longer break.

When to use it

Deep, demanding work such as writing, programming or research

Long study blocks before an exam

Creative projects that need momentum

Anyone who already focuses well and is bothered by short timers

You might prefer it if…

01short timers break your concentration just as it builds
02you want to stay in the zone through the break
03you can protect an hour and a half without interruptions

Tips for 90/10

Do not start with this rhythm if starting is hard; warm up with a short block.

Even a 10-minute break needs a real break: stand, stretch and drink water.

One or two blocks a day is already a lot of deep work.

Compared with other rhythms

90/10 has the same block as 90/15 with a shorter break. If you need more recovery, use 90/15, and if 90 minutes feels long, 60/10 is the step down.
