Study Timer — Free Online Pomodoro Timer

Focus in timed cycles and watch the hours add up. Choose 25 min / 5 min or 50 min / 10 min, and VClock tracks every completed session for the last 30 days.

How to use the VClock study timer

Step 1 Pick your cycle length Tap 25 / 5 for the classic Pomodoro cycle or 50 / 10 for longer, deeper blocks. The choice locks once a cycle is running so a session can't be re-timed underneath you.
Step 2 Start focusing Tap Start focus and put your phone face-down. The ring drains as the block runs, so a glance tells you roughly how long is left without reading a number.
Step 3 Take the break you're offered A chord plays and the timer offers the break. Actually take it — stand up, look out of a window. The break is what makes the next block work, not a reward for finishing the last one.
Step 4 Watch the day add up Each finished focus block is banked into today's total and into a 30-day chart below the timer. Seeing yesterday's bar is a better motivator than any streak counter.

Why timed blocks beat studying until you're tired

Studying "until it's done" has no edges, and work without edges expands to fill whatever time you give it. A timed block does the opposite: it converts an intimidating, open-ended task into a concrete commitment — 25 minutes on this chapter — which is small enough to start without negotiating with yourself. The break is scheduled before you are tired rather than after, which is why the second and third blocks feel much like the first.

The method is Francesco Cirillo's Pomodoro Technique, named after the tomato-shaped kitchen timer he used as a student. The mechanism has nothing to do with tomatoes and everything to do with the commitment being visible and finite.

25 / 5 or 50 / 10 — which cycle suits your subject

25 / 5 suits problem sets, flashcards, vocabulary, past papers, and revision — work made of many small units, where a 5-minute gap costs you nothing because you can resume at the next question. Its long break lands after four sessions, roughly every two hours.

50 / 10 suits essays, long-form reading, proofs, and programming — work with a long warm-up, where 25 minutes ends about the time you have finally loaded the whole problem into your head. Its long break lands after two sessions. If you find yourself resenting the break bell, that is the signal to move up to this cycle.

Tracking study hours without tracking you

The chart below the timer shows your focused minutes for each of the last 30 days. It is deliberately coarse: VClock stores one row per calendar date holding a session count and a minute total, and no clock times at all. That is enough to show whether you studied more this week than last, and not enough to reconstruct when in the day you were at your desk. Everything stays in your browser's local storage on your own device — there is no account and no server copy — so the log is per-browser and "Clear history" erases it immediately.

Frequently Asked Questions

What is a study timer?

A study timer breaks a study session into fixed blocks of focused work separated by short breaks, instead of leaving you to study for an open-ended stretch. VClock runs the cycle for you: it counts down the focus block, tells you when to break, counts the break down too, and keeps a tally of how many blocks you have finished.

Which cycle length should I choose?

Start with 25 / 5 — 25 minutes of focus, 5 minutes of break, with a 15-minute long break after every fourth session. It is the original Pomodoro cycle and the easiest to sustain. Switch to 50 / 10 for reading, essay writing, or coding, where 25 minutes is barely enough to get properly started; that cycle takes a 30-minute long break after every second session.

Does the study timer keep running if I switch tabs or pages?

Yes. The countdown lives outside the page you are looking at, so it keeps running if you navigate to another VClock tool, and the floating status widget shows the time remaining. It does need the browser tab to stay open — closing the tab ends the session.

Does VClock track how many hours I have studied?

Yes. Each completed focus block is added to a daily total, and the last 30 days are kept so you can see your streak. The log records only the date, the number of sessions, and the total minutes — never clock times — so it cannot reconstruct what time of day you were at your desk. "Clear history" deletes it instantly.

Where is my study history stored?

In your own browser's localStorage, on your own device. Nothing is uploaded, there is no account, and no server ever sees it. The flip side is that the log is per-browser: it will not follow you to a different device, and clearing your browser's site data erases it.

Is the study timer free?

Yes — free, with no account, no sign-up, and no download. The site is funded by advertising.

How is this different from the regular countdown timer?

The countdown timer is for any single duration you type in — 7 minutes for tea, 90 seconds for a plank. The study timer has no duration field at all: it runs a repeating focus-and-break cycle and logs your totals. Use the countdown timer for one-off durations and the study timer for study sessions.

Does it play a sound when the block ends?

Yes. A short chord synthesised in the browser via the Web Audio API plays at the end of every focus block and every break, so you can look away from the screen while you work. No audio files are downloaded and no permissions are required.
