Pomodoro Timer
Focus on one task at a time using the Pomodoro Technique — 25 minutes of concentrated work, followed by a 5-minute break. After four sessions you earn a longer 15-minute break. Enter the task you're working on, click Start, and the timer will alert you when it's time to switch. All session lengths are adjustable. Pair this with a study schedule to plan which subjects to tackle each day, and use the homework planner to track what's due.

About the Pomodoro Technique
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s. He used a tomato-shaped kitchen timer (pomodoro is Italian for tomato) to break his work into intervals separated by short breaks. The core idea is simple: decide on a task, work on it with full attention for 25 minutes, take a 5-minute break, then repeat. Every four sessions, take a longer 15–30 minute break to fully recharge. Some students prefer a physical tomato kitchen timer on their desk as a tangible commitment device, though the digital timer above works just as well.
The technique works because it forces you to commit to a single task at a time, removes the temptation to multitask, and makes large projects less intimidating by breaking them into short, manageable bursts. The built-in breaks also prevent the mental fatigue that comes from long unbroken study sessions.
For students, the Pomodoro Technique is especially effective during exam preparation when there is a large amount of material to cover. Pair it with a weekly study schedule to plan which subjects to tackle on which days, and use the semester grade tracker to monitor whether your study effort is translating into grade improvements.
Frequently Asked Questions
Can I change the 25-minute session length?
Yes — click the Settings gear icon to customize focus session length, short break length, long break length, and the number of sessions before a long break. A common variation is to use 50-minute sessions with 10-minute breaks, which works well for university-level study or complex problem sets.
What should I do during the break?
Stand up, stretch, get water, look away from the screen, or take a short walk. The break works best when it is a true mental rest — avoid checking social media or email, as these create new mental threads that make it harder to refocus. Short breaks are meant to clear your working memory, not fill it with new information.
What if I finish a task before the timer ends?
Use the remaining time to review what you just completed, read ahead, or refine your notes. The original technique recommends overlearning — using leftover time to deepen your understanding rather than starting a new task. Alternatively, you can use the Skip button to advance to the break early.
What if I'm interrupted mid-session?
If you can defer the interruption, note it down quickly and return to work. If you cannot, use the Pause button to hold the timer and deal with it, then resume. If the interruption is long enough to break your focus entirely, reset the timer and start the session fresh. The goal is to protect your attention for the full 25 minutes as often as possible.
Is 25 minutes enough for deep studying?
For many tasks — reading, flashcard review, problem sets — 25 minutes is ideal because your attention naturally peaks and dips. For tasks that require a long warm-up time, like writing a difficult section of a paper or solving a complex proof, consider using the 50/10 variation or even 90/20 intervals to match your natural ultradian rhythm. The right interval length is the one that keeps you focused without burning out.
