Hi Product Hunt 👋

I work late on a Mac with two monitors, and every blue-light tool I tried treated them as one screen. My laptop would warm up while the external display stayed bright, or the other way round.

So I built LumenBar. It follows your day automatically, from daylight through evening into sleep, and every display can now follow that look, stay neutral, or keep its own warmth. Unplug a monitor and plug it back in, and it remembers.

A few other things I wanted for myself:

• Eleven ready looks, from Health and Sleep to Reading and Gaming

• A 20-20-20 break reminder with a soft chime

• Automatic pause when Photoshop, Figma, or Final Cut is in front

• No account, no cloud, nothing sent anywhere

It's free and notarized by Apple. It runs on Apple silicon Macs with macOS 26.

What would make the evening part of your day easier? I'd love to hear which looks you end up using.
