If you got a new monitor for your Mac, you noticed there's no way to control its brightness from the Mac.
Lunar brings back brightness control for monitors, along with volume, contrast, input switching and can even turn off monitors or the built-in display.
Lunar 4 brings support for controlling monitors on M1 Macs, auto-learning curve when adjusting brightness, external light sensor support and Facelight which allows you to use an external monitor to light up your face in video calls.
Lunar gives your Macbook adaptive brightness for external displays, and an easy way to manage brightness and contrast without fiddling with the (usually) hard to press physical buttons of the monitor.
