About Nox

Nox is a native macOS menu bar display filter built for light-sensitive users. Start from one of twelve presets, or adjust tint, software dimming, black point, contrast, grayscale, temperature, and individual color channels yourself. It supports scheduling, break reminders, and connected displays, and runs on macOS 14 or later with a 14-day trial before a one-time purchase.

Features

  • 12 Presets: Start from a ready-made filter instead of building one from scratch.
  • Tint Control: Apply a color tint across the display to soften what you're looking at.
  • Software Dimming: Take the screen below the brightness floor macOS gives you on its own.
  • Black Point & Contrast: Adjust how deep the blacks go and how hard the contrast is.
  • Grayscale & Temperature: Drop color entirely, or shift the display warmer or cooler.
  • Individual Color Channels: Tune the red, green, and blue channels separately for finer control.
  • Scheduling: Have filters come on and off automatically at the times you choose.
  • Break Reminders: Built-in prompts to step away from the screen.
  • Connected Displays: Works across the external displays attached to your Mac.
  • 14-Day Trial, One-Time Purchase: Try it for two weeks, then buy once, no subscription.

Why Nox?

macOS gives you Night Shift and a brightness slider that stops well above "dark enough" for some people. Nox adds finer control, software dimming below the system floor, per-channel color, black point and contrast, with presets so you don't have to dial it all in yourself.

Choose from twelve presets to find a starting point that suits your eyes.

Fine-Tune

Adjust tint, dimming, black point, contrast, temperature, or individual color channels.

Automate
