Study timer
The study timer opens on the pattern most students start with: 25 minutes of work, a 5-minute break, and a 15-minute break after every 4 pomodoros. Brown noise is on by default, because a low, steady rumble covers dorm and library noise without the hiss of white noise, and it can be changed or turned off. No account is needed, and it works on a phone as well as a laptop.
This page suits students revising for exams, working through problem sets, or reading assigned chapters, and anyone with a long list of medium-sized tasks who needs a fixed rhythm. 25 minutes is enough to finish a section of notes and short enough that starting is not a commitment.
It is a poorer fit for work that needs a long warm-up, such as an essay from a blank page or a single hard proof, where a break every 25 minutes cuts the thread. The 45/15 and 4 x 45 timers are built for that. Whether Pomodoro helps study at all is an open question: Ogut (2025) found mostly positive but self-reported outcomes across 32 studies, while Smits et al. (2025) found no productivity difference in a 2-hour trial.
Questions
how many pomodoros should I study a day
There is no researched number. 8 pomodoros is about 3 hours 20 minutes of focus, or roughly 4 hours of clock time with breaks. Start with 4 and see how you feel. More pomodoros with worse attention is not a win.
is 25 minutes long enough to study
For reviewing notes, flashcards, and short exercises, yes. For essays and long proofs, many students find 25 minutes ends just as they get going and move to a 45 or 50-minute block instead. Try both and keep the one you finished more in.
should I study with brown noise on
Only if it helps you. Some students find a low, steady sound makes a busy library easier to ignore, others prefer silence. Run one block each way and notice which one had you looking up less often.
