What this timer is for
Countdown runs one block of time you choose and tells you when it is over — a single task, a rest, an exam practice.
Starting a session
Pick a quick preset or set your own hours, minutes and seconds, then press Start. The duration can be edited whenever the timer is idle.
While it runs or is paused you can add five minutes at any time with the +5m control beside the main action.
Pause and resume
Pause holds the remaining time; Resume continues from exactly there.
Reset and restart
Reset returns the countdown to its full duration. Once it has finished, Start again runs the same duration once more.
Progress
The ring fills as the time passes and the digits show what remains. With percentage on, the exact share sits beneath the timer.
Sounds and voice
When the countdown reaches zero the completion alert plays. Choose the sound and volume under Sound & Alerts.
Customization
Appearance sets the progress style, thickness, presence and colour, the clock face and font, and the background. Keep screen awake, under Behavior, holds the display on while it runs.
Focus Mode and fullscreen
Focus Mode quietens the workspace around the timer; Fullscreen gives it the whole screen. Neither pauses the countdown.

Common questions
- Does it keep counting if I leave the tab?
- Yes. The countdown is measured by the clock, so it finishes at the right moment whether or not the tab is visible.
- Can I restart the same duration?
- Yes — after it finishes, press Start again; before it finishes, Reset returns it to the full duration.
- Can I add time without stopping?
- Yes. The +5m control adds five minutes while the countdown runs or is paused; press it as often as you need.
