Blue Light Filter

Blue Light Filter makes your screen warmer and more comfortable for nighttime reading, browsing, studying, and everyday phone use.

Apply a customizable blue light filter in one tap and adjust the screen tint exactly the way you want. Choose a quick preset or fine-tune the intensity, red, green, and blue values to create your preferred warm screen.

Blue Light Filter and Night Mode

Turn on the blue light filter whenever your screen feels too cool or bright at night. A warm screen filter is applied across your apps, giving you a softer night viewing experience without changing the content you are viewing.

Quick Presets

Switch between ready-made screen filter presets in seconds:

• None
• Reading
• Relax
• Night
• Warm

Pick a preset and continue using your phone without manually adjusting every color setting.

Fine-Tune Your Screen Filter

Want more control? Customize your night filter with precise controls for:

• Filter intensity
• Red level
• Green level
• Blue level
• Custom screen tint

Save your settings and quickly apply your preferred warm screen whenever you need it.

Works Across Apps

The blue light filter uses a simple screen overlay so your selected tint can remain visible while you browse, read, message, or use other apps.

No Root Required

Use the screen filter without rooting your Android device. Set your preferred color, adjust the intensity, and control the filter directly from the app.

Light and Dark Appearance

Choose the interface that suits you:

• Follow system theme
• Light appearance
• Dark appearance

The clean interface is designed to look comfortable during both daytime and nighttime use.

Start After Reboot

Enable auto-start on boot when you want your saved screen tint to be reapplied after restarting your phone.

Check Your Filter Status

The Status screen gives you a quick overview of:

• Current filter state
• Saved RGB tint values
• Filter intensity
• Start-on-boot setting
