Beyond Night Shift
Apple’s filter warms your screen slightly. Sundown can remove blue and green light output entirely for a true red mode before bed.
Mac-native evening light control
For the last screen session before sleep
Your screen, as red as the sunset.
Sundown is a Mac menu bar app that shifts your display fully red after dark — far beyond Night Shift. Built for people who work late and still take their evenings seriously.

Fade at sunset7:48 PM
From daylight to candlelight in one click. Night Shift stops at amber. Sundown goes all the way.
Designed for wind-down rituals
Less harsh light. More control.
Sundown is intentionally simple: it changes the light coming from your Mac, then gets out of the way.
Set it and forget it
Schedule Sundown to follow local sunset or your own wind-down time. A gradual fade makes the shift feel natural.
Lives in your menu bar
No dock clutter. Toggle instantly, adjust intensity, or use a keyboard shortcut when you need color accuracy back.
Careful science, practical utility
Why red light in the evening?
Bright, blue-heavy screen light at night is the opposite of the light our evenings evolved around — firelight, sunsets, candles. Research into circadian rhythms has focused on blue wavelengths as a strong daytime signal, which is why many people choose to limit them after dark.
Sundown makes that choice effortless: it reduces the blue and green light your display emits, nothing more.
Sundown is a screen utility, not a medical device. It does not diagnose, treat, or prevent any condition.
Not another warm tint
Why not just use Night Shift?
f.lux and Night Shift are great for warming things up. Sundown is for going all the way down.

Questions before sunset
FAQ
How is this different from Night Shift?
Night Shift warms your screen. Sundown can shift it fully red — a much stronger filter with finer control.
Will it distort colors for design work?
Yes — that is the point. Toggle it off instantly when you need color accuracy.
Does it slow down my Mac?
No. Sundown adjusts display output natively and is designed to use negligible resources.
Which Macs are supported?
The launch target is macOS 13 Ventura and later, on Apple Silicon and Intel Macs.
Is it a subscription?
Never. Sundown is planned as a one-time purchase.
