Study timer
Pick a length, press Start, study until it rings. Breaks and a session count are built in.
Space starts and pauses. Keep this tab open for the sound.
SHORT VERSION
- Pick one topic, pick a length, press Start. The timer above handles study, break and the count.
- Start with 25 / 5. Move to 50 / 10 once you can finish four sessions without drifting.
- Plan the day in sessions, not hours. Three to six good sessions is a strong study day.
- Use the last two minutes of each session to recall what you learned, with the book closed.
How to use this study timer
- Pick a length. 25 / 5 is the classic pomodoro. 50 / 10 suits problem sets. 90 / 20 is for long, deep sessions. Custom lets you set your own.
- Choose one topic. Write it on paper so you do not have to decide again halfway.
- Press Start and study until it rings. The time left is in the tab title, so you can glance without leaving your notes.
- Take the break. With the auto option on, the break starts by itself, then the next study session.
- Stop after three or four sessions for a longer rest. The count under the timer shows how many you did today.
Six study tips that make the timer work
Pick the topic first
Write down one chapter or one problem set before you press Start. Choosing mid-session eats the focus.
Take the break for real
Stand up, drink water, look out of a window. Scrolling your phone is not a break for your brain.
Test yourself
Spend the last few minutes of a session recalling what you just read, without looking. It sticks better than rereading.
Match the length to the work
25 minutes for reading and review. 50 or 90 minutes for problem sets, essays and coding that need a warm up.
Count sessions, not hours
Four good sessions beat six distracted hours. The counter under the timer keeps score for today.
Stop while you can
After three or four sessions, take a long break. Tired study turns into rereading the same page.
Which study length should you pick?
| Preset | Good for | Watch out for |
|---|---|---|
| 25 / 5 | Reading, flashcards, review, getting started on a hard day | Can cut you off just as a problem gets going |
| 50 / 10 | Problem sets, lab reports, most homework | The last 10 minutes need real discipline |
| 90 / 20 | Essays, coding, past papers in exam conditions | Too long if you are tired or new to timed study |
| Custom | Matching your class length or an exam section | Keep the break at least a fifth of the study time |
Who this study timer is for
Students before exams
You have a pile of topics and a date. Sessions turn the pile into pieces you can finish and count.
Working students
Two hours after a shift is not much. A timer stops those hours from leaking into your phone.
Self learners
Courses, languages, certificates. No teacher sets the pace, so the session count does.
A sample study day with the timer
Here is one real day for a university student with classes in the afternoon, using the 50 / 10 preset in the morning and 25 / 5 in the evening when energy is lower.
That is five sessions and about three hours and ten minutes of real study. It does not sound like much. It is more than most people manage in a whole "study day" at the library.
Sample study weeks
A student three weeks before exams
| Day | Sessions | Preset | What goes in them |
|---|---|---|---|
| Monday | 5 | 50 / 10 | Maths past paper sections, then marking |
| Tuesday | 4 | 25 / 5 | Biology reading and flashcards |
| Wednesday | 5 | 50 / 10 | Essay plans for two likely questions |
| Thursday | 4 | 25 / 5 | Weak topics from Monday's marking |
| Friday | 3 | 90 / 20 | One full past paper in exam conditions |
| Saturday | 3 | 25 / 5 | Light review of the week's mistakes |
| Sunday | 0 | Rest | Plan next week's topics on paper |
A working student or freelancer taking a course
Say you work 9 to 5 and study for a certificate at night. Aim for two 25 minute sessions on weekdays and three 50 minute sessions on Saturday. That is 10 short sessions plus 3 long ones, a bit over six and a half hours a week, which is enough to finish most online courses on time. The trick is starting the first session within ten minutes of sitting down, before the evening fills itself.
How to plan exam revision in sessions
- List every topic on the syllabus. One line each.
- Guess the sessions per topic. An easy topic might be one 25 minute session. A hard one might be four 50 minute sessions.
- Add them up and compare with your days left. If you need 60 sessions and have 15 days, that is four a day. If you need 60 and have 8 days, cut or start today.
- Put the hardest topics early in the day and early in the plan, so there is time to come back to them.
- Save the last few days for past papers in 90 / 20 blocks, the closest you can get to the real exam.

Common study timer mistakes and how to fix them
| Mistake | What happens | Fix |
|---|---|---|
| No topic picked | The first ten minutes go to choosing | Write the topic down before you press Start |
| Phone as the timer | You check one message and lose the session | Use this tab and put the phone in another room |
| Skipping breaks | Session three and four get slow and sloppy | Leave the auto option on so the break just starts |
| Breaks that grow | A 5 minute break turns into 40 | Stand up and move, do not start a video |
| Only rereading | It feels like study, little sticks | End each session with two minutes of recall, book closed |
| Counting hours | Sitting at a desk counts as studying | Count finished sessions instead |
If you only change one thing: pick the topic before the timer starts.
Browser timer, phone app or a real clock?
| Option | Good | Not so good |
|---|---|---|
| This page | Nothing to install, works on PC and Mac, counts sessions, time in the tab title | Needs the tab open for sound |
| Phone app | Works away from a laptop | Puts the most distracting thing on your desk |
| Kitchen or sand timer | No screen at all | No session count, no automatic breaks |
| Desktop focus app | Can tie the timer to your task list | More setup than a school week needs |

Questions people ask
What is a study timer?
A study timer splits study time into focused sessions with short breaks in between. You study until it rings, rest until it rings again, then start the next session. The timer on this page does that for you and counts your sessions.
How long should a study session be?
There is no single right length. The classic pomodoro is 25 minutes of study and a 5 minute break. Many students prefer 50 minutes and 10 off for problem sets, or 90 and 20 for deep work like essays. Try a few days of each and keep the one where you stay focused to the end.
Is this a pomodoro timer for studying?
Yes. The 25 / 5 preset is the Pomodoro Technique. The timer switches between study and break on its own if you tick the auto option. Read more in our guide to the pomodoro technique for studying.
Does the study timer work in the background?
Yes. It counts from the clock, not from the page, so it stays right in a background tab. The time left shows in the tab title. Keep the tab open so the sound can play.
Can I set my own study time?
Yes. Pick Custom and type any study and break length from 1 to 180 minutes. Your choice is saved in this browser.
Does it count my study sessions?
Yes. Every finished study session adds one to today's count under the timer. It resets the next day and is saved only in your browser.
Is there a study timer app for PC?
This page works in any browser on a PC, Mac, tablet or phone, with nothing to install. If you want a focus timer tied to a real task list on your desktop, SayBriefly has one for Mac and Windows, though it is built for work more than for school.
Is SayBriefly a study app?
Not really. SayBriefly is built for people who work with clients: calls, email, tasks and a calendar that share one memory. Its focus timer runs on tasks from your to-do list. Students who freelance or run projects use it, but this study timer on the web is all you need for revision.
Is this study timer online and free to use?
Yes. This study timer runs online in your browser with no signup and nothing to install. It saves your settings and today's session count only in this browser.
What is the best study timer app for students?
The best one is the one you actually open every day. A browser tab like this page is enough for most students: presets, breaks, sound and a session count. A phone app can help if you study away from a laptop, but it also puts your phone on the desk, which is the thing most people need to move away.
Can I use a study timer on my PC or Mac?
Yes. Open this page in Chrome, Edge, Safari or Firefox on a Windows PC or a Mac. Keep the tab open, and pin it if you want it to stay put. The time left shows in the tab title while you work in other windows.
How many study sessions a day is enough?
For most students, four to six focused sessions of 25 to 50 minutes is a solid day on top of classes. Before exams some people push to eight. Past that, quality usually drops faster than the count goes up.
Is 30 minutes a good study session length?
Yes. 30 / 5 or 30 / 6 works well if 25 feels too short. Pick Custom, type 30 for study and 5 or 6 for break, and the timer keeps it for next time.
What should I do in a study break?
Move and rest your eyes. Walk, stretch, refill water, look at something far away. Avoid starting a video or a chat, because it is hard to stop when the break ends.
It's 4pm on a Friday. The brief is locked, the client is happy, and Scribbble already sent the meeting recap. You close the laptop.
That's the point.
