About this app

Quite simply you can the set desired brightness for any application, and it will be automatically applied on app launch. You can choose one single brightness value, two different brightness levels for day and night, an Auto Brightness with an adjustment level, or even create your own auto-brightness service that uses whatever values you want. You can also purchase the option to control audio levels, play music, set the display's sleep time, and turn on or off wifi and bluetooth for each app.

Unlike other apps which constantly run in the background this app has zero effect on battery and performance. This was achieved through the use of Android's accessibility features.

App supports dark mode.

New features coming soon!

Important note: This app requires accessibility permission to get notified when a new app is launched, and it requires the permission to modify system settings so it can change brightness and any other parameters. If you don't feel comfortable granting these permissions then you cannot use this app.

By installing you automatically agree to the license information detailed in the app.

Ratings and reviews

Overall, the auto brightness curve is good. I wish the transition between different brightness can be smoother. Not just jump to it. Also after exiting per app, it often doesn't reset to auto even that's my global default. I noticed the app was killed or crashed.

Just found that the Auto Brightness Adjustment is very dark until its maximum level is set which looks just acceptable. But after a few hours of idleness, I found such setting is unstable during staying still in a video player and a browser which are turned to be very sharp or very dark problematically. Sometimes even slightly flickering the brightness during my sitting still on a chair. I can only stop to use it. Besides, enabling the Percentage doesn't work.

Love this app. One thing people should know is if your phone has an optimize battery setting you need to go into this apps setting on your phone and disable that for the brightness app. The app doesnt tell you this but the optimize battery puts apps to sleep when in the background. If this app is asleep it cant see what app you are in the adjust your brightness. Luckily I knew that but for people that dont they will just assume the app doesnt work. Might want to add this info in the app settings
