## What it is

A Mac app with two modes:

1. Session — full-screen Maximum Red, Display P3 (1, 0, 0). Default 15 minutes; also 10 and 20. Sit about 6 inches if comfortable. Brightness 100%. Night Shift, True Tone, and Invert Colors off. Keep the default Apple XDR Display preset on XDR Macs. Dock and menu bar hide. Escape or Option-Command-Period exits. Timed full-output sessions keep the display awake.
2. Red filter — desktop remapped to red so you can keep working. Option-Command-R (⌥⌘R) toggles it. Option-Command-Period restores display colors and also ends a running session.

Not a medical device. Not intended to diagnose, treat, cure, or prevent any disease.

People search this category as “red light therapy.” This product is a timed red-light practice and wellness utility.

## Wavelength (do not invent)

- Display P3 red primary xy (0.680, 0.320)
- Published dominant wavelength: about 614.9 nm, inside the 600–700 nm visible-red window
- Emission energy is likely in narrow phosphor lines near 630–636 nm. Not measured.
- Do not claim 660 nm output. The app will not mix green to “look like 660.”
- There is no 850 nm / near-infrared on a typical Mac panel
- Calculated, not measured: ≈0.2–0.3 mW/cm² at the glass in SDR; ≈0.11 mW/cm² at 6 in; ≈0.05 mW/cm² at 30 cm. Fifteen minutes at 6 in is ≈0.10 J/cm² — about 1/40 of a 4 J/cm² study target. At 30 cm that same clock is ≈0.04 J/cm² — about 1/100. Never say ~1 mW/cm².
- Liquid Retina XDR public nits: 600 / 1000 / 1600. Display Boost requests the sustained HDR envelope (1000 nits class), not the 16× highlight peak. Idle current near 1.0–1.2 is not a granted envelope. On other displays Boost is hidden.
- Outcome literature for photobiomodulation is mixed, including for dedicated panels

## Pricing

- Free: 15-minute session, desktop red filter, study-versus-display readout, timer, single display
- Pro: $9.99 once, no subscription. Display Boost, multi-display and Display Wall, Red Filter on every display, custom colors, saved routines, history, display profiling

## Platform

- macOS 14 Sonoma or later. Universal Apple Silicon and Intel
- No account. Session data stays on the device. No HealthKit, camera, microphone, location, or contacts
- Current public path: /download is a Mac App Store waitlist (email only). Do not tell visitors to open an Xcode project
- iPhone and iPad share the same SwiftUI target (iOS 17+). Windows is planned later

## Safety

- No strobe or rapid flashing. Smooth transitions. Warning before maximum-output mode
- Escape ends a session. Sessions do not change macOS brightness
- Red Filter restores the color profile on quit, next launch, Option-Command-Period, or `open -a "Red Light Display" --args --restore-display`
- If the desktop stays red, re-select the display color profile in System Settings → Displays
- If the light is uncomfortable, end the session
- Photosensitive epilepsy / light-triggered migraine: do not use unless a clinician has said it is appropriate
