Low Brightness is a lightweight Android app that lets you dim your screen below the system minimum, perfect for using your phone in the dark without straining your eyes.

Customize everything with ease: choose the dimming color, adjust the opacity, measure ambient light with the built-in lux meter, or schedule automatic activation. No root required. No internet needed. Just a clean, fast, Material You inspired interface.

Our app is designed to be simple and easy to use, while also being fast and lightweight.

Benefits

How it works
Use the lux meter to check the ambient light level around you. Then add the Night Screen tile to Quick Settings, grant the needed permissions, and tap it whenever you want to dim the display. Adjust the slider for brightness or pick your favorite overlay color. You can also set a schedule to activate dimming automatically.

Accessibility disclosure
Low Brightness uses the AccessibilityService API only to keep the dimming overlay visible over other apps while you reduce the brightness. The service does not log or share any personal data and you may disable it at any time in system settings.

Ratings and reviews

There's a lot of ads. Despite there being a quick setting, I wasn't able to get it to toggle like the app says it should. Tapping it opens the app and brings it to foreground, frequently showing an ad that has to be manually closed before you can adjust anything. The only reason I'm not rating lower is the author publishes with GPLv3. I haven't reviewed what they share on GitHub thoroughly other than that the APKs from there still require Play Store and have ads, but it's nice for transparency.

This is the best lower brightness app I have found. It works great, and even allows you to disable ads if you find them to be too annoying.

didn't use wasn't great
