Sleep timer
Set a timer and Umbraa fades the screen to black when it ends. Fall asleep to a movie and it won't be a bright screen that wakes you at 3 a.m.
Every display
Works on all connected screens, including external monitors.
Umbraa for macOS

Neutral, warm, or red.
Neutral keeps colors true. Warm shifts them amber for late evenings. Red cuts nearly all the blue and green light.
Fade to black, now or later.

One click blacks out every display right away, with no timer to set. Tap the screen to bring it back.
A fully native Mac app.
Umbraa is written entirely for macOS, so it feels like part of the system rather than something bolted on. It stays fast, light, and out of your way.
Lives in your menu bar
Dim, warm, or black out the screen from the menu bar, whatever app you're in.
Keyboard shortcuts
Adjust dimming, toggle Umbraa, and start the sleep timer without reaching for the mouse.
Sunset to sunrise
