About this app

I want the screen brightness to adjust automatically, but the automatic adjustment built into my phone doesn't quite match my preferences!

Even when I set the screen brightness to the lowest setting, it's still too bright and uncomfortable!

This app was created to solve those problems.



You can set the brightness threshold (brightness sensor value) and the brightness level to be set.

You can select the operation mode from "Stop," "Only when Sleep is Wake Up," and "Always."

If you select "Only when Sleep is Wake Up," it will only operate from the time the screen turns on until the brightness sensor value stabilizes.

(If you move from a bright place to a dark place, please turn the screen OFF and then ON again.)

You can pause/resume operation from the status bar.

You can also specify the screen brightness when paused.

(This is useful when you want to temporarily fix the screen brightness, such as when displaying coupons in a store.)

*For Android 13 and later, user permission is required to use notifications, so please allow notifications if you want to use this function.

It will automatically start working even after restarting your phone. This app does not include any unnecessary features such as advertisements.


The brightness (illuminance) value detected by your smartphone varies from device to device.
Please refer to the "Current Illuminance" displayed in the app to find a comfortable setting for changing the brightness (the illuminance setting to change).
You can also launch the app by touching the notification in the status bar, so you can quickly check the current brightness this way.


On Android 6.0 and later, you cannot change the brightness without user permission.
The settings screen will appear the first time you launch the app, so please grant permission.

In previous versions, you could set whether or not to display the notification icon, but due to changes in Android specifications, displaying it is now mandatory, so this setting has been removed from the advanced settings. Thank you for your understanding.
