How to use it
- Set hours, minutes, and seconds, or pick a preset. The 5, 10, 15, and 30 minute pages open with that duration already set. The timer stays idle until you press Start. For a focus block followed by a break, use the Pomodoro timer.
- Pause keeps the remaining time. A refresh keeps a paused timer paused.
- A running timer stores its deadline. Coming back shows the time left, or Finished if the deadline passed.
- Preview sound before you rely on it. The chime plays only while this tab is open.
- Fullscreen puts the remaining time in the center of the screen. Press Escape or Exit to leave.
Limits to know
- There is no background timer. Closing the tab or sleeping the device can miss the sound.
- If the device clock jumps during a running countdown, Clockbeam keeps the remaining interval and shows a note.
- Share setup sends the duration and sound, not a live remote control. The label is included only if you turn that on.
Questions
Does the countdown keep running if I refresh?
A running timer resumes from its saved deadline. A paused timer stays paused. If the deadline already passed, the timer shows finished and does not play a late sound from the reload.
Why did the timer finish without a sound?
Sound starts only after you press Start or Preview sound, and only if a sound is selected. A hidden or sleeping browser cannot promise playback.
Can I save a timer for next time?
After a timer finishes, you can name it and save it in this browser. You can also save, export, and delete setups from Customize.
