Built for the moments when a countdown needs to soothe rather than push. The column drains slowly, the bubbles drift at their own pace, nothing flashes and nothing ticks. Mute the alarm from the header and it ends in silence, which is usually what a regulation break needs.
A free sensory timer: a calm liquid column that drains slowly with drifting bubbles. No flashing, no ticking and no numbers unless you want them — designed for calm corners, regulation breaks and sensory rooms.
TimerHub calculates remaining time from an absolute finish timestamp, so missed browser callbacks do not create drift. Read the timing accuracy methodology and reproducible tests.
Common Uses
- Calm corner and regulation breaks
- Sensory rooms

How to Use the Sensory Timer

- Use the Fullscreen control below the timer for a room-sized countdown (Esc to exit)
- Choose or mute the alarm sound from the sound settings in the header
Frequently Asked Questions
Can I turn off the alarm completely?
Yes. Mute sounds with the speaker button in the header and the timer ends silently, with just the liquid reaching the bottom. That matters when a sudden noise would undo the point of the break.
Does it animate constantly?
The bubbles drift slowly and stop when the timer is not running. If you or a student prefer no motion at all, your browser's reduced-motion setting is respected across the whole site.
Can I put this on a projector or smart board?
Yes. Press Fullscreen under the timer and the drawing fills the display at whatever size the screen allows. Esc exits. For a Chromecast or AirPlay setup, cast the browser tab and then go fullscreen on the source machine.
Can I embed this timer in my own page?
Yes. Every timer here has a copy-and-paste embed code that drops a working countdown into a class blog, a lesson page or a school site, with no account and no script tag.
Does it need an account or an app?
No. It runs in the browser with no signup, no install and no ads, which is what makes it usable on a locked-down school machine.
