3 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. |
