Your screen's minimum brightness is still too bright. Whether you're reading in bed, managing eye strain, or navigating light sensitivity and migraines, the system brightness slider just isn't enough. Lux solves this.

Lux is a screen dimmer that goes below your device's minimum brightness using a software overlay — giving you real control in dark environments. Built with Material You design for Android 14+, it's the modern night mode utility your phone has been missing.

🔅 CORE FEATURES

• Lower Brightness Beyond the Limit
Reduce screen brightness far below what Android allows natively. The system slider has a floor — Lux goes beneath it. Whether you need a subtle reduction or a deep dim for complete darkness, the overlay adapts to your preference. Perfect for late-night reading, eye care, and migraine relief.

• System-Wide Dimming
The overlay covers your entire display — status bar, navigation bar, notification shade, and all apps. No gaps, no bright edges. Every pixel on your screen is uniformly dimmed for a comfortable viewing experience across your entire device.

• Quick Settings Tile
Toggle dimming on or off directly from your notification shade in one tap. No need to unlock, find the app, or navigate menus. Add the Lux tile to your Quick Settings panel and control brightness as easily as toggling Wi-Fi.

• Notification Controls
Adjust the dim level directly from a persistent notification — increase, decrease, or toggle dimming without leaving what you're doing. Full control stays at your fingertips while you browse, read, or work.

• Adjustable Intensity
Fine-tune exactly how dim you want your screen. From a light filter for slightly dim rooms to a deep overlay for pitch-black environments — you set the level, and Lux holds it consistently.

💡 WHY CHOOSE LUX?

Unlike legacy screen dimmers that haven't been updated in years, Lux is purpose-built for modern Android.

→ Material You Dynamic Theming — adapts to your wallpaper colors and respects system dark mode. It looks native to your device, not like a utility from 2016.

→ No Ads. No Tracking. No Data Collection — your privacy is absolute. Lux does not connect to external servers or run analytics. Everything runs locally on your device.

→ Smooth Software Overlay — a clean, flicker-free layer for dimming. No visual artifacts. Gentle on your eyes even at the lowest levels — ideal for light sensitivity and headache-prone users.

→ Lightweight & Efficient — minimal battery impact with no background processing beyond the active overlay. No bloat, no resource drain.

🔒 ACCESSIBILITY PERMISSION TRANSPARENCY

Lux requests the Accessibility Service to extend the dimming overlay above all system UI elements. Without it, dimming only works inside apps — the status bar and navigation bar remain bright.

✓ Places a dimming layer above system UI for full screen coverage.
✗ Does not read or capture screen content.
✗ Does not monitor keystrokes or input.
✗ Does not collect, store, or transmit personal data.

A clear disclosure dialog explains this before you enable it. You can revoke the permission from Android Settings at any time.

• Eye strain and migraine relief in dark environments

Lux is free, private, and built with care. No ads today, no ads ever. Lower your screen brightness the right way.
