Pomodoro & Focus Timers
Focus timers make a working session finite. Knowing that a stretch of concentration has a defined end makes it easier to begin, and the enforced pause afterwards is what stops a long day turning into a shallow one. Students, remote workers and anyone prone to drifting into a browser tab will recognise the problem. The Pomodoro Timer follows the established pattern of a working interval, commonly twenty-five minutes, followed by a short break, with a longer break after several rounds. Its strength is rhythm. The countdown acts as a commitment device for tasks you have been avoiding, and the break prompt stops you working past the point where the quality drops. It suits admin, coding, marking and anything that can be broken into small units. The Study Timer is the better fit when the work needs a longer continuous run, such as reading a chapter, sitting a practice paper or writing a section of an essay. You set the duration to match the task rather than to a fixed cycle, and you track the total time spent across a session. Pick the Pomodoro rhythm when starting is the hard part, and the study timer when interruption is the hard part. Both run in the browser without sign-up.

Pomodoro Timer
A Pomodoro timer with custom session lengths, auto-start options, a chime alert and a daily focus count.
Study Timer
Plan up to ten study sessions with custom study and break lengths, auto-start, a chime and notifications.
How the session schedule is assembled
So for N sessions the schedule contains N study phases and N minus 1 breaks, giving 2N minus 1 phases in total. The planned total time is therefore N multiplied by the study length, plus N minus 1 multiplied by the break length.
Each phase counts down independently and the schedule panel shows where you are in the sequence. When a phase ends, the alert options fire if enabled, and auto-start either advances immediately or waits for you. Time studied accumulates only from study phases, so breaks do not inflate the figure. The study slider moves in 5-minute steps between 5 and 180 minutes, and the break slider in 1-minute steps between 1 and 60.
A four session afternoon planned out
The schedule becomes seven phases: study 1, break 1, study 2, break 2, study 3, break 3, study 4. That is 4 study phases and 3 breaks, matching the N and N minus 1 rule.
The arithmetic on total time: 4 multiplied by 50 gives 200 minutes of study, and 3 multiplied by 10 gives 30 minutes of break. Added together the block runs 230 minutes, which is 3 hours and 50 minutes. Start at 13:00 and you finish at 16:50, with the time studied counter reading 200 minutes at the end.
Compare that with a classic Pomodoro setting of 25 minutes study and 5 minutes break over the same 4 sessions: 4 multiplied by 25 gives 100 minutes of study and 3 multiplied by 5 gives 15 minutes of break, so the block runs 115 minutes and ends at 14:55 with half the study time.
Choosing lengths that suit the work and the caveats
Use breaks as real breaks. Standing up, getting water or looking out of a window restores attention in a way that scrolling a feed does not, and short breaks are easier to end.
A few practical limits. The timer runs in the page, so the tab needs to stay open, and background tabs on some phones throttle timers. Desktop notifications only appear if you grant the browser permission when asked, and the chime needs your device volume up and not muted. Finally, these session lengths are working conventions rather than clinical prescriptions; adjust them to what actually works for you.
