About:
Flux is a screen color temperature controller that adjusts your display's hue based on the time of day. It reduces blue light exposure in the evening to promote better sleep and reduce eye strain. The app runs continuously in the background, seamlessly adapting your screen's warmth to match natural sunlight.
Key Features:
  • Automatic color temperature adjustment based on location and time
  • Reduces blue light to minimize eye strain and sleep disruption
  • Customizable color temperature settings and transition speeds
  • Minimal system resource usage while running in the background
Use Cases:
  • Nighttime computer use without disrupting sleep patterns
  • Reducing eye fatigue during long work sessions
  • Maintaining consistent lighting conditions for creative work
Alternatives:
  • night-shift – Built-in macOS feature with less customization than Flux
  • iris – Cross-platform alternative with additional monitor control features
