Applies a shade that acts as a dimmer to ensure your eyes don't hurt. Far more powerful than Android's built-in brightness setting. Great for low-light gaming, web browsing, and eBook reading. It even saves battery life for AMOLED displays!

• Tasker/Locale Plug-in! Set brightness based on time/place/etc. To disable, configure for 100% brightness.
• Brightness slider uses logarithmic scale for fine-grained control.
• Drag the app icon to your desktop to use for toggling on/off.
• Prompts to confirm very low brightness settings.
• Option to disable soft-key backlight (does not work on all phones).
