Deep Work Timer
60 minutes of distraction-free focus, then 15 minutes of real rest. Built for the kind of work that actually moves the needle.
What is deep work?
Deep work, a term popularized by Cal Newport's 2016 book of the same name, refers to professional activity performed in a state of distraction-free concentration that pushes your cognitive capabilities to their limit. It's the kind of work that creates new value, improves your skill, and is hard to replicate. Email, meetings, and Slack are not deep work. Writing, designing, coding hard problems, learning difficult material — these are.
How to use this deep work timer
- Schedule deep work in advance. Don't wait until you "feel like it" — that almost never happens during a busy day.
- Choose one task before you start. Deep work doesn't multitask.
- Block out 60–90 minutes minimum. Deep work doesn't fit into 15-minute slots.
- Press Start. The timer counts a 60-minute deep work block followed by a 15-minute rest.
- When the rest period starts, actually stop. Walk, eat, look at the sky — anything that isn't another screen.
Deep work rules that matter
- One screen, one task. If your task needs two windows, that's fine. If it needs eight, you're probably context-switching, not working.
- Phone in another room. Studies show even a face-down phone on the desk reduces working memory capacity.
- No "just checking" anything. Email, Slack, news, social — not even once during the block. Save it for the break.
- Stop on time. Pushing past your limit reduces the next block's quality. Discipline goes both directions.
How long should a deep work block be?
Newport recommends 60–90 minutes as the realistic range for most people, with the upper end (the 90-minute timer) matching the body's natural ultradian rhythm. If you're new to deep work, start with 30–45 minutes and build up — the skill of sustained focus is trainable but doesn't appear overnight. Most experienced deep workers manage 2–4 blocks per day, totaling 2–4 hours of true deep work. That's enough to do extraordinary things.
Deep work vs other focus methods
The 25-minute Pomodoro is for fragmented tasks. The 52/17 timer sits in the middle. Deep work blocks (60–90 minutes) are for the high-value, hard-to-replicate work that creates the biggest wins in a career. Use all three — they're tools for different jobs, not competing methods.
Frequently asked questions
What is a deep work timer?
A deep work timer is a focus timer designed for the long, distraction-free work blocks Cal Newport describes in his book Deep Work. Typically 60–90 minutes of focused work followed by a 15–20 minute rest.
How long should a deep work session be?
60–90 minutes is the practical range for most people. Shorter than 60 and you don't have time to load the deep context. Longer than 90 and quality usually drops. Build up to it gradually if 60 minutes feels long now.
How many hours of deep work can you do per day?
Newport and other researchers suggest 2–4 hours per day of true deep work is the realistic upper bound for most people. That's why the work that comes out of those hours is so valuable — almost nobody can sustain more.
Is deep work the same as flow?
They overlap but aren't identical. Flow is the felt experience of total absorption in a task. Deep work is the structural commitment to the conditions that make flow likely. You can do deep work without entering flow, and you can experience flow during work that isn't 'deep' in Newport's sense.
