27 minute timer at a glance
| Accuracy | Counts to an absolute finish time, so it stays exact in a background tab and after the device sleeps. How the timing is tested |
|---|---|
| Alarm | Loud bell & beep that rings until you press Stop, with the whole screen flooding sunrise-warm. Chime, bell, beep, a shorter ring or a silent glow under More. |
| Display | Large digits that never jitter, a progress horizon, and a fullscreen Clear view (or Daylight, for bright rooms) readable across a room. |
| Sound | Optional rain, ocean, fireplace, café, night, brown or white noise and a focus pad — made in your browser, faded out at zero. |
| Memory | A running or paused countdown survives a reload or a browser restart, saved on this device only. |
| Price | Free. No ads, no signup, nothing to install — and it works offline once visited. |

About the 27 minute timer
Set a 27 minute timer for a focused work block, study session, or workout interval. The 27 min countdown runs in the browser with an alarm when it finishes.
Set a 27 minute timer that shows its finish time before you commit, survives a throttled background tab, and alarms at zero. Optional ambient sound, fullscreen display, and push alerts if you close the tab.
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.
