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.

*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:

darker.STOP
darker.PAUSE
darker.INCREASE_5
darker.INCREASE_10
darker.DECREASE_5
darker.DECREASE_10
darker.SET_10
darker.SET_20
darker.SET_30
darker.SET_40
darker.SET_50
darker.SET_60
darker.SET_70
darker.SET_80
darker.SET_90
darker.SET_100
darker.TOGGLE_COLOR
darker.ENABLE_COLOR
darker.DISABLE_COLOR

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"

darker.START

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.

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.

This app is fantastic! I have a cheap government phone from assurance wireless. I tried to turn down the brightness but the screen was still very bright. Even applying the built in night light feature didn't help. Then I found this app and it solved my problem. It's very convinent because you can turn it on from the home screen. Also, no ads! Unfortunately it doesn't apply systemwide but I guess it's Androids fault and not this app. Overall it's a great app and I would recommend.

Experience has been great until Aug 2021, but now, some app buttons do not respond anymore when the Darker filter is applied. Not sure what happened, but it took a while to figure out what was going on: some of the newer updated apps (like my banking app, and others) suddenly stopped working. An internet search led me to turning off the darker setting, and voila: all of my "broken" apps starting working again. Unfortuante, because Darker is the most light weight, unobtrusive filter out there.
