Black Screen With Clock

A deliberately dim bedside night clock on a pure black screen. Adjust only the clock glow, choose 12- or 24-hour time, then hide everything else.

Clock glow11%

Only the clock is dimmed here; your device's hardware brightness remains under your control.

A night clock that stays dark around the time

The background is pure black and the clock itself can be reduced to a faint glow. On OLED and AMOLED displays, the black pixels can switch off individually; LCD displays may still emit some backlight.

Designed for bedside use

The controls disappear after you start the clock. The time shifts by a few pixels over longer intervals instead of holding exactly the same OLED footprint all night, and you can request a browser wake lock when you need the screen to stay visible.

Want a gradual sunrise too?

The full This Quiet World app includes an optional browser-based sunrise sequence. It needs the page to remain open and should not replace a device-level alarm for anything you absolutely must wake for.
