About this app

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.

This app is fully functional and does not include advertisements. Additional paid features are unlockable through an In-app purchase.

Xiaomi device / MIUI users need to go to Settings → Installed apps → Darker → Other permissions, and enable "Display pop-up window" for Darker to work correctly.

Paid features include:

» Auto-On & Auto-Off
» Start at boot
» Lower brightness below 20%
» Darken navigation bar
» Custom filter colors
» Root mode
» 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, color filter)

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.

Darker requires the use of accessibility services to darken the screen, no data will be accessed or shared via the AccessibilityService API.

*The color filter is similar to how the desktop version of f.lux works. Selecting a redder color will reduce more bluelight emitted from the display.

Tasker Support
Darker has Tasker support, use these intents to send commands to Darker:


Add the above intents to Tasker by going to Action Category→System→Send Intent→Action, leave the other fields default, and note that the intents are case sensitive.

These two intents below need an additional parameter in the "Extra" field

darker.SETCOLOR "Extra" field: COLOR:1~16 (Colors are numbered left to right, top to bottom)
darker.COLORSTRENGTH "Extra" field: STRENGTH:1~10

The intent below needs the "Target" field set to "Service"


FlickStart Support
Darker can work in conjunction with FlickStart, an app which can send commands to Darker by using the sensors on your phone or Android Wear device.

The command set for Darker is available for download on the FlickStart website. Simply download the command set and import it into FlickStart.

It works, but it constantly and unpredictably turns off. Then when I go to reenable if, I have to reenable permissions, and go through about 6 clicks every time. I have no idea if this is a quirk of it being free or some other shenanigans. I'll be moving on to something more consistent with a better UI/UX. This would easily be 1 star except it works when it works.

When you take screenshots they appear much darker. Given the permissions you already have in order to run the app, it seems possible to turn off the dimming right as a screenshot is taken to get around this, but I don't know how the app works internally or if this is actually possible. Other than this, it works great and is super easy + simple to use! I had some issues before where the amount the screen dimmed by was inconsistent, but I haven't had that problem in a while.

Oh my god, thank you! I would give six stars if I could. Finally, a blue light filter and screen darkener that you CAN TURN OFF! Why the heck none of the others let you do that is beyond me, but I will never use an app that demands a constant background process. I just want to turn things on when I need them and off when I'm done. Thank you so much. There are also other features that nobody else has but I find essential, like lowering the brightness below the hardware limit. 10/10, perfection.
