Blue-light filter + super dimmer for Windows
Overlay a warm tint and an extra-dim layer on top of everything. Always-on-top, click-through, multi-monitor, and auto-updates.
Super dim
Reduce perceived brightness beyond the system minimum with a soft black layer.
Warmth control
Cut blue light with a configurable warm tint for late-night comfort.
Click-through
Overlay never blocks interaction. Toggle anytime from the tray.
Multi-monitor
One overlay per display. Handles hot-plug and layout changes.
Auto-launch
Optional start with Windows. Set it once and forget.
Auto-update
Updates via GitHub Releases; deltas are tiny.
How it works
We draw two transparent, always-on-top layers: a dim black layer and a warm tint. This reduces perceived brightness and blue light without touching your display’s backlight. It’s compatible with most apps and games.
Privacy
No telemetry. No network calls except checking for updates. Settings are stored locally on your device.
