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)

If the first launch falls - run again
