The problem with studying is not the studying, it is the forty minutes before it where you open six tabs, look for a pen, decide the desk needs clearing first, and then remember you were supposed to start. A timer does not fix that on its own. What it does is put a number on the screen that says this is the block, this is how much of it is left, and you are in it.
This is a plain countdown with nothing attached. Set the duration in minutes, press Start, and a large time readout takes the result area: 25m 00s counting down second by second. The Start button turns into Pause, so you can stop for a door or a phone call and pick up where you left off rather than starting again.
Twenty-five minutes is the default because that is the number most people try first. The input accepts anything from 1 minute up to 480, which is eight hours, so it works for a short recall sprint just as well as for a long exam rehearsal. Blank or nonsense in the box and it quietly falls back to 25.
A full-screen distraction-free timer for focused study sessions. Set your duration, press start, and stay on task.
How the timer works
Set the minutes, press Start. The readout appears and ticks down every second. Under an hour it shows minutes and seconds, so a 25 minute block reads 25m 00s and a 4 minute one reads 04m 00s. Over an hour it adds the hours, so 90 minutes displays as 1h 30m 00s.
The same button starts and stops it. Press Start and it runs; press it again while it is running and it pauses with the remaining time intact; press it a third time and it resumes from that number, not from the top. Reset stops everything and clears the display, which is what you want when you have changed your mind about the length.
At zero the readout is replaced with Time is up! and the countdown stops by itself. There is no alarm to dismiss and no auto-start of another block — you decide whether the next 25 begins or the session ends there.
Setting it up for a real session
Pick the length before you press Start, not after. The number matters because a session with no ending drifts: give yourself 4 hours and you will spend the first hour deciding what to do with the other three. Ninety minutes with a defined target written down beats an open afternoon, every time.
Some lengths that work for specific jobs. 25 minutes for one problem set or one chapter. 50 minutes if you are deep in something and do not want the interruption, which reads as 50m 00s. 1h 30m 00s for a past paper under exam conditions, with the last five minutes reserved for checking your answers rather than writing more.
Write the target where you can see it before you start. “Chapter 7 questions 1 to 12” or “rough draft of the introduction”. A timer with no target is just time passing with better branding, and when the display hits Time is up! you want a clear yes or no on whether the thing got done.
What this timer does not do
It does not block anything. The tabs are still there, the phone still lights up, and the tool has no way to stop you opening a video. That part is on you, and the honest version of distraction-free is removing the temptation before you press Start — phone in another room, unrelated tabs closed, one window if you can manage it.
It also does not save your sessions. Close the tab and the countdown is gone, because nothing is stored anywhere. Switching to another tab usually keeps it running, though browsers slow down timers in background tabs, so do not use it to time anything where the exact second is the point.
And there are no breaks built in. The 25 is just a default value, not a claim about optimal focus, and if you want a structured cycle with rest periods built in, that is a different tool. This one is deliberately thin: a number, a start, a pause, and a finish.

- Eye break timer — the rest interval this timer deliberately skips
- Handwashing timer — 20 seconds, a completely different job
- Morning routine timer — sequence the blocks before the day starts
Frequently asked questions
Can I pause it and come back?
Yes. The Start button becomes Pause while it runs, and pressing it again resumes from the time left rather than resetting. That is the point of using one button for both.
What happens when it reaches zero?
The readout is replaced with “Time is up!” and the countdown stops. Nothing else happens — no sound, no second block starting. You choose what comes next.
How long can I set it for?
Anywhere from 1 to 480 minutes. Four hundred and eighty is eight hours, which is long enough for a full mock exam day. Anything under 1 or not a number falls back to 25 minutes.
Will it keep counting if I switch tabs?
Usually, but browsers throttle timers running in the background, so it can drift on a long hidden run. Keep the tab visible when the timing matters, and never close it mid-session because the countdown is not stored.
Is this a Pomodoro timer?
No. There are no built-in breaks and no cycle of four, and the 25 minute default is only there because it is a common starting length. Use it as a plain countdown, or pair it with a separate break reminder if you want the structured version.
