    Nor f.lux, the warm light software that got Sherlocked by every major OS. https://justgetflux.com/. - Source: Hacker News / about 2 months ago
  • Show HN: Monchromate โ€“ the best greyscale browser extension
    Somewhat related: I really like f.lux's "Darkroom" feature. Although I no longer use the app to reduce blue light after the advent of macOS's Night Shift, Darkroom mode tints the screen completely red (like a red version of Color Filters). It's great for working during the wee hours. https://justgetflux.com/. - Source: Hacker News / 12 months ago

  • Tools that keep me productive
    For those evenings where I'm in front of the computer, f.lux is a must. Like some wise person said, "Be kind to your eyeballs". macOS's Nightshift kind of works, but f.lux destroys it. - Source: dev.to / about 2 years ago
