Intelligent adaptive brightness for your external display.. Lunar controls the same brightness that you can change by using the monitor's physical buttons.

-Sensor-based Adaptive Brightness (and contrast) based on an external light sensor
-Sync-based Adaptive Brightness (and contrast) based on the built-in light sensor of the Macbook or iMac
-Location-based Adaptive Brightness (and contrast) based on the sunrise/sunset times in your location
-App Exception list if you need more brightness for specific activities (watching movies, design work)
Individual settings per display
-Manual controls and hotkeys for setting brightness and contrast that respect the min/max values per monitor
-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/Software controls are not used)

Supported Operation Systems
macOS 10.15 or later (Apple Silicon compatible)
