f.lux 4.140

f.lux automatically adjusts your screen's colors, warming them at sunset and returning them to daylight tones at sunrise. Research suggests your computer might be keeping you awake late into the night.

Use f.lux to improve your sleep quality or simply to enhance your screen's appearance. It adapts your computer's display to match your environment—making it feel like part of your room. After sunset, your screen mimics the warmth of indoor lighting, while in the morning, it brings back natural sunlight tones.

Just tell f.lux about your location and lighting setup, and it takes care of everything automatically.
