App Brightness Manager handles the needs of most users and manages the brightness by application layer. You can also get the Pro version to remove the ads. If you feel that your device does not reach 100% brightness even when you set it to 100 %, please calibrate your devices to 100% in settings to fix it. Some manufacturers manage the brightness of the device differently from the default method.
* Preset brightness setting by app
* Automatically change brightness when you open the configured app
* When you exit the configured app, the brightness of the device restores the default brightness
* Clean and intuitive user interface.
