The defacto app for controlling monitors. Intelligent adaptive brightness for your internal and external monitors.

Lunar changes the hardware brightness of the monitor using the DDC protocol.

It doesn’t use a software overlay if the monitor supports DDC/CI.


It doesn’t interfere at all with the native adaptive brightness that macOS implements for the built-in display.

It works well along Night Shift and True Tone (and f.lux if Gamma dimming is not used).
