Set it, then forget it
Auto follows your real local sunrise and sunset down a smooth warm-light curve — neutral by day, golden in the evening, warmest at night. No abrupt jumps, no fiddling.
Or pick your glow
Reading
A warm, paper-like wash for the long haul.
Morning
A soft, low-glare wake-up.
Focus
Calm and quietly un-distracting.
Night
The warmest, dimmest of the bunch.
One Strength dial turns it all up or down — and you can craft your own custom modes.
No hand-wavy science
Every color has a reason, and Ember shows its work: a built-in guide links the vision and circadian research behind each mode — including an honest take on what a screen tint can and can't do.
Yours alone
Ember reads your location only on your Mac, only to find your sunrise and sunset. Nothing is collected, stored, or sent. No account, no tracking, no nonsense.
