2 hour 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 2 hour timer
Set a 2 hour timer (also a 120 minute timer) for study blocks, work sessions, gaming, or cooking. The countdown runs in your browser with a sound alarm and notifications.
A 2 hour countdown that keeps time from an absolute target rather than counted ticks, so it stays accurate through background tabs and sleep. Shows its finish time, runs fullscreen, and alarms at zero.
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.
