Sundown.
Sundown is a Mac menu bar app that warms and dims the screen after dark, down to 500K deep red — well past Night Shift's 2700K limit. One slider. No account.
~58% more melatonin · ~24 min longer sleep (Ostrin 2017)
Three beats. That is the whole program.

You already know how to make these.
Three posts you could film tonight. Take them word for word or make them yours — they are written to be true, which is the only rule we have about copy.
Night Shift stops at 2700K. Sundown keeps going, down to 500K deep red. Same desk, same hour, two completely different screens. Link in bio. Free for 7 days.
Suggested visual
Film your Mac in a dark room and drag the slider on camera. The screen turning red is the whole ad.
Are you macro dosing blue light? Your screen was calibrated for noon. You are using it at 11pm. Your body keeps score either way. Link in bio. Free for 7 days.
Suggested visual
You, lights off, laptop open, face lit warm. One take, no edit. The room does the work.
Ostrin 2017 found that blocking blue light in the evening raised nocturnal melatonin about 58 percent in healthy adults, and they slept about 24 minutes longer. That study used lenses. Sundown takes the blue out of the screen itself. Link in bio.
Suggested visual
Plain white text on a still of a dark room with one warm screen glowing. Let the number carry it.
People whose audience is awake after dark.
Wellness creators
Your audience already cares what light does to a body after dark. This is the screen half of that conversation, and nobody is having it.
Biohackers
Kelvin, flicker, dithering, schedules. Sundown is one of the rare things in the stack you can demo on camera in ten seconds.
Anyone whose audience works on a Mac at night
Founders, editors, engineers, students. If they are on a Mac after dark, you do not have to explain the problem to them.
Take your nights back. Bring your audience with you.
