52/17 Timer: 52 minutes work, 17 minutes break
Focus25:00
The 52/17 method pairs 52 minutes of focused work with a generous 17-minute break. It comes from time-tracking data rather than a productivity book, and it suits people who find classic Pomodoro breaks too short to truly recharge. This timer is already set to 52/17, with a 30-minute long break after every fourth session, so you can press Start and get going.
Where does the 52 17 rule come from?
In 2014, the time-tracking company DeskTime looked at how its most productive users organized their day. What stood out was not the number of hours they put in but their rhythm: on average, they worked for about 52 minutes, then took a break of roughly 17 minutes before starting again.
That observation became known as the 52/17 rule. It is not a controlled experiment and 52 is not a magic number, but it suggests that people who get a lot done alternate long, fully focused blocks with breaks long enough to truly step away, rather than working for hours with half their attention.
How to follow the 52/17 method with this timer
- 1Plan the 52 minutesPick one task, add it to the task list and write down what "done" looks like for this session.
- 2Work at full intensityThe method only works if the 52 minutes are real work, so close chat, mute notifications and keep your phone out of reach.
- 3Leave your desk for the breakSeventeen minutes is enough for a walk, a snack or a short conversation, so spend it away from screens.
- 4Take the long break after four roundsFour 52/17 cycles add up to more than four hours, so the 30-minute break is a good moment for lunch or a proper reset.
52/17 vs. 50/10 vs. the classic Pomodoro
On paper, 52/17 and 50/10 look similar: both give you close to an hour of focus. The difference is the break. Ten minutes is enough to refill a coffee; seventeen minutes is enough to go outside, eat something or have a real conversation. With 52/17 you spend about three quarters of your time working, compared with roughly 83% for both 50/10 and 25/5.
That lower ratio is the point, not a flaw: the 52/17 rhythm treats rest as part of the work, so you come back sharper instead of slowly fading through the afternoon.
- Choose 52/17 for draining knowledge work such as analysis, writing and coding, or on days when you need more recovery.
- Choose 50/10 when you want more total focus time and recover quickly.
- Choose 25/5 when you struggle to start or your work is made of many small tasks.
- All three are in the preset menu under the timer, so you can switch in one click.
Common mistakes with the 52/17 rule
The most common mistake is turning the 17-minute break into 17 minutes of social media: scrolling feels like rest but keeps your attention busy and makes the next session harder to start. Another is stretching the break "just this once". The alarm is there to bring you back; turn on auto-start in the settings if you want the next session to begin on its own.
And when the break arrives in the middle of a thought, jot down in one line where you stopped before you get up. Restarting is much easier when you know exactly what comes next.

Frequently asked questions
Is the 52/17 rule scientifically proven?
Not in a strict sense. It comes from DeskTime's analysis of how its most productive users worked, which is an observation rather than a controlled study. Still, alternating focused work with real breaks is widely recommended, and many people find this particular rhythm comfortable.
Why 17 minutes and not 10 or 15?
The number simply reflects the average break DeskTime observed among its top users. What matters is that the break is long enough to fully disconnect from the task. If 17 minutes feels too long, shorten it in the settings and keep the 52-minute focus block.
How many 52/17 cycles fit in a workday?
An eight-hour day fits about six cycles, including a longer lunch break. Many people find that four to six real focus blocks already make a very productive day. The stats panel shows how many sessions you complete, so you can find your own sustainable number.
Does the 52/17 timer keep running in the background?
Yes. The countdown is based on timestamps, so it stays accurate in a background tab, after a reload or when your computer sleeps. You can also pick an alarm sound and enable desktop notifications so you never miss the end of a session.
