I’m the Red Light Display concierge. First session is usually a 15-minute full-screen session — sit about 6 inches if comfortable (or 30 cm / 18 in), brightness 100%, Night Shift, True Tone, and Invert Colors off. If you need to keep working, use the red filter instead. I will not diagnose or treat anything. When you’re ready, go to /download.
Safety
Comfort first.
A bright red screen should be easy to leave. These are the guardrails in the app.
- No rapid flashing and no strobe feature.
- Smooth color and brightness transitions.
- A warning before maximum-output mode.
- Escape immediately ends a session.
- Original brightness is restored when the app changed it.
- Normal screen-lock behavior unless you enable keep-display-awake.
- Red Filter restores the display color profile on quit and next launch.
This is a consumer red-light and wellness utility, not a medical device. It is not intended to diagnose, treat, cure, or prevent any disease. If the light is uncomfortable, end the session.
