Suggest a timerPick one of the durations above and the countdown starts straight away - there is no start button to hunt for and nothing to set up. The remaining time also shows in the browser tab, so you can switch to your notes and still see it.
Tap 5, 10, 25, 45 minutes or any other preset. The countdown starts on the tap.
The remaining time appears in the tab title, and the countdown keeps correct time even in a background tab.
A soft two-note chime plays when the time is up. Add a minute or five if you need to keep going.
Open one of the full-screen clocks below for a distraction-free screen you can leave running all evening.
Most visitors arrive with one specific length in mind. These are the durations people set most often, and what they set them for.
| Duration | What it is for |
|---|---|
| 1-3 minutes | Plank holds, brewing tea, a breathing break, a speaking exercise |
| 5 minutes | A short break, a warm-up, quick recall practice between topics |
| 10-15 minutes | Reading a chapter, a quick revision sprint, a timed exercise |
| 25 minutes | One pomodoro - the classic focused work block, followed by a 5-minute break |
| 45-60 minutes | A full study session, a lecture-length block, an exam practice run |
A countdown you can see turns an open-ended task into a short, finite one. That is the whole mechanism behind the pomodoro technique, and it is why a timer on the screen beats a timer in your head.
Committing to 25 minutes is much easier than committing to "studying". The end is visible before you begin.
A timed break ends on its own. Without one, five minutes on your phone quietly becomes forty.
When the remaining time is on screen, you stop breaking concentration to wonder how long is left.
Finishing a block feels like finishing something, even when the work itself is not done.
Everything about the free timer and the full-screen clocks.
The timers are free for anyone to use, and always will be. If you are here because you are studying, diStudero turns your own materials into flashcards, quizzes, mind maps and practice tests with AI.
