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.
- Timed sessions keep the display awake by default. You can turn off “Keep display awake during sessions” in Settings.
- Red Filter does not keep the display awake; normal sleep and screen-lock settings still apply.
- 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.
