Darker can lower your screen brightness to extremely low levels, to help prevent eyestrain during the night. Use the built-in color filter* to adjust the color of your display, perfect for filtering out harsh white backgrounds during the night.
Users can either upgrade the free version to Pro through in-app purchase, or directly purchase this version (for countries that don't support In-app purchases) - both are the same in terms of functionality.
Features only in the Pro version:
В» Auto-On & Auto-Off
В» Start at boot
В» Lower brightness below 20%
В» Darken navigation bar
В» Customizable notification buttons
• Up to three buttons can be added for quick access.
• Buttons to increase and decrease the brightness (+5%, -5%, +10%, -10%)
• Buttons to set a specific brightness (@0%, @10%, @20%, ... , @90%, @100%)
• Quick toggles (stop, pause, reset)
Note: When manually installing APK files, Android blocks the "Install" button from being pressed when Darker is running. This is NOT a bug. It's a protective measure to prevent malicious apps from camouflaging the install button. Pausing Darker will solve this.
*The color filter is similar to how the desktop version of f.lux works. Selecting a redder color will reduce more blue light emitted from the display.
