Why a disk beats digits
Instead of counting down digits, the disk shows remaining time as a shape. As time passes the disk shrinks counterclockwise, so one glance tells you how much is left — no math, no squinting.
Visual timers were first designed for kids learning the concept of time, and they are now everywhere: classrooms, homework desks, meetings and deep-work sessions. Wontimer brings that experience to your browser and adds what a physical timer cannot: an automatic record of your focus time.
How to use it
- Drag the disk (or press a preset) to set the time.
- Press Start or the spacebar. Tapping the center knob also starts and pauses.
- When time is up an alarm rings, and the session is added to today’s record.
Focus with Pomodoro
The Pomodoro technique alternates 25 minutes of focus with a 5-minute break, and after four rounds you take a longer 15-minute break. Short sprints keep starting easy, and fixed breaks keep distractions short.
You can change every duration in the Pomodoro tab. Turn on auto-start and focus and breaks will follow each other by themselves.

Frequently asked questions
There's no sound
Wontimer runs quietly with no ticking, and an alarm plays when time is up. If you can’t hear it, check in Sound and display that Alarm sound isn’t set to Silent and the volume isn’t at 0 — opening the silent timer page switches the alarm to Silent. On phones, check the mute switch: iPhones mute web audio when the silent switch is on.
Is it accurate if I switch to another tab?
Yes. Remaining time is computed from the real clock, so it never drifts while you are in another tab. On supported browsers the screen also stays awake while the timer runs.
Where is my focus history stored?
Only in this browser. Nothing is sent to a server and nothing is shared across devices. Clearing this site’s browser data also clears the history.
What counts toward focus history?
Pomodoro focus phases and time actually elapsed in timer mode. Breaks are excluded. You can exclude timer mode too under Sound and display.
Can I set more than 60 minutes?
Switch the dial scale to 120 minutes under Sound and display to set up to two hours on the disk. The custom input accepts up to 180 minutes.
The alarm is late when the tab stays in the background
The math is based on the real clock, but Chrome may put long-unused tabs to sleep. Pin the tab, or add this site under Chrome settings → Performance → Always keep these sites active.
Can I move my history to another device?
Use Export history to save a file, then Import history on the other device. Duplicate sessions merge automatically.
Notifications don't show up
Check that "Notify me when time’s up" is on, that this site is allowed to send notifications in your browser settings, and that your OS is not in do-not-disturb mode.
Can I use it on a classroom smartboard?
Yes. Open Wontimer on the board and press Focus mode (or the F key) to show just the disk in full screen, big enough to read from the back of the room. On supported browsers the screen stays awake while the timer runs, and the silent timer turns the alarm off when the class needs quiet.
Does a visual timer help if I lose track of time?
Visual timers are widely used by people who find it hard to sense time passing, including in special education and ADHD support, because the shrinking disk shows what is left without reading numbers. You can hide the digits, and the mini timer keeps the disk in view over other windows. Wontimer is a timer, not a medical tool.
Can a meeting or study group use the same time?
Set the time, then press “Share a link with this time”. The link opens Wontimer already set to that length, so everyone sees the same timer and starts it on their own screen.
Can I get a warning before time runs out?
Yes. Under Sound and display, turn on a heads-up 1, 2, 5 or 10 minutes before the end. You get a short message and a soft two-note chime (no sound if the alarm is set to Silent).
What if I miss the alarm?
Under Sound and display, turn on “Repeat alarm until dismissed”. The alarm rings again every 6 seconds for up to a minute and stops as soon as you tap the screen or press a key, in any Wontimer tab or the mini timer.
Can I add time without stopping the timer?
Yes. While the timer runs or is paused, press +1 min. Each press adds a minute, up to 30 extra minutes and 180 minutes in total, and the disk grows to match.
Can I time a speech with green, yellow and red signals?
Open the speech timer page. The disk turns green, yellow and red at the times you set, and after red the time over counts up.
