Outcomes first

What you get from the screen on your desk.

A timed session on your Mac

Choose a full-screen red session, with a timer and an easy exit. Morning Red and Low Light are built in.

Red while you keep working

Use ⌥⌘R to toggle a live red filter while keeping your desktop usable.

Clear about the difference

A Mac display is not a dedicated panel. Its calculated output is not a measured panel dose. Explore the science.

Two ways

A timed session, or a live filter.

15-minute session

Start a 15-minute full-screen red session, or choose Morning Red or the 30-minute Low Light session. The soft-grid appearance is for wellness and ambiance, not treatment. Press Escape to exit. See how sessions work.

Live red filter · ⌥⌘R

Keep your desktop usable while its colors are remapped to red. Toggle the filter with Option-Command-R. Option-Command-Period restores colors and ends a running session.

Straight answers

Straight answers before you start.

Is this 660 nm?

Display P3 red’s published dominant wavelength is about 614.9 nm, a color description rather than a measured emission peak. The app does not provide 660 nm LED or 850 nm near-infrared output.

Is this medical?

No. This is a timed red-light session and wellness utility. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease. People search the category as red light therapy. Clinical benefits have not been established for this app.

Is a laptop enough?

A laptop is not a dedicated panel. Calculated output is about 0.2–0.3 mW/cm² at the glass. Choose it for timed sessions and a desktop red filter on hardware you already own — not as a substitute for a measured panel dose.
