Auto Shine

Auto Shine is an Android utility that adjusts screen brightness on its own instead of leaving the level fixed or relying entirely on the system default. It takes over the job of deciding how bright the display should be, so the screen can follow changing lighting conditions during the day without the user reaching for the brightness slider each time.

The app is published by Valent-in and released under the GPL-3.0-only license, so the source may be studied, modified and redistributed under those terms. It is packaged for Android only; there is no desktop or other mobile build, and the behaviour depends on what the device itself exposes for display control. Anyone looking for a small single-purpose tool that handles one system setting, rather than a general device configuration suite, will find the scope here narrow by design.
