An online timer counts down from a set time (e.g., 25:00, 01:10:30). When it reaches zero, it triggers a sound alarm and/or visual signals. It's ideal for studying, workouts, cooking, presentations, quick reviews, and mindful breaks—all directly in your browser and without registration.
Unlike a stopwatch (which counts up from zero), a timer counts down to 00:00. You can use quick presets or set custom hours, minutes, and seconds, with Play/Pause/Stop controls, an on-the-fly +1 min button, and a progress ring that shows the remaining time.
How to use (step-by-step)
Set the time: adjust hours, minutes, and seconds, or click a preset.
Start the countdown: click Play. Keep the tab open (it can be in the background).
Pause/Resume: use Pause and resume with Play whenever you want.
Add +1 min: while the timer is running, click +1 min to extend the time.
Stop/Reset: when finished, stop the alarm and reset the time for a new cycle.
Mute: use the Mute button when available to silence the alarm without losing the state.
App features (highlights)
Quick presets: a grid of minutes to quickly fill the form.
Custom time: dedicated inputs for hours, minutes, and seconds (with validation).
Clear controls:Play, Pause, Stop, +1 min, and Mute (when applicable).
Progress ring: an animated circle that reflects the remaining percentage.
Status feedback: accessible (aria-live) status messages during execution.
Integrated audio: sounds for the interface and final alarm (subject to browser autoplay policy).
Privacy by default: everything runs locally; no data is sent to servers.
Responsive interface: good readability on desktop and mobile devices.
Practical tips
Test the sound first: click any button to "unlock" audio and avoid volume surprises.
Use fullscreen for presentations: improves visibility of the ring and digits.
Avoid setting 00:00: validate the time before starting to prevent an immediate finish.
Plan your increments: the +1 min is useful, but avoid extending indefinitely without tracking.
Power saving: on laptops, reduce brightness and keep only the timer tab open.
Common mistakes to avoid
Accidentally clicking Reset: use Pause if you intend to resume, not Stop/Reset.
Alarm with no sound: some browsers require prior interaction; click something first.
Closing the tab: ends the countdown and alarm; there is no subsequent "catch-up."
Suspending the system: hibernation freezes execution; adjust if necessary upon return.
Overlapping alarms: stop one alarm before starting another to avoid multiple sounds.
Frequently Asked Questions (FAQ)
Can I run multiple timers? This page focuses on one main timer; open new tabs for multiples.
Does it work offline? Yes, after the initial loading of local files.
What happens when it reaches zero? The display locks at 00:00, the ring completes, and the alarm sounds (if enabled).
Can I change the sound during the countdown? Generally, yes; the new sound will be used at the next completion.
Is there a visual alert? The ring and the final state clearly indicate completion.
Can the browser lag? Background tabs may be throttled; the timestamp-based logic reduces deviations.
Summary
The timer transforms set periods into objective, manageable blocks. Combine presets and custom time with Play/Pause, +1 min, and a final alarm to give your activities a rhythm—simply, privately, and efficiently.
