Sky Ember
Your screen, timed to your sky.
Sky Ember warms your Mac's display the way the sky warms at dusk, gliding from daylight neutral to candlelight as the sun sets over your horizon. And when true darkness matters, one click takes you where no built-in setting can: pure red.

Follow the sun
One on-device location fix. Your screen tracks the sun's real arc: neutral only at midday, gold by late afternoon, candlelight at dusk. Nothing to schedule.
True red mode
Green and blue removed entirely. Not tinted, gone. The wavelength that spares night vision and melatonin. Night Shift can't do this.
Flicker-free dimming
Dim below the backlight's minimum without PWM flicker. The image darkens, the light never pulses. Made for dark rooms and sensitive eyes.
Private by architecture
No accounts, no analytics, no network code at all. Sky Ember cannot phone home. Your location never leaves your Mac.
In rhythm with your body
Bright, blue-rich light in the evening tells your brain the day is still going. It delays melatonin, nudges your body clock later, and keeps your eyes working harder than they need to at night. Sky Ember eases your screen along the same curve as natural light: bright and neutral while the sun is high, warm and gentle once it is gone, so the last hours of screen time feel closer to lamplight than to noon.
The astronomer's secret, one click away
Astronomers, pilots, and stargazers have used red light for a century. It is the wavelength your night vision ignores. Sky Ember's Red mode turns your whole screen into that lamp: reading beside a sleeping partner, checking something at 2 AM, winding down before bed.
