The tool app described offers the functionality to adjust the screen orientation and rotation independently of the displayed application's attributes. Users can fix the screen in a specific orientation or allow it to rotate based on the device's sensor. The app provides the convenience of changing screen orientation from the notification area and allows for associating specific applications with customized screen orientation settings.

The app operates by displaying a transparent, untouchable UI layer above other applications, giving it higher priority in screen orientation adjustments. Even after closing the app, it remains resident in the background to display the UI in the notification bar. However, this mechanism comes with limitations such as the inability to hide the notification bar and potential recognition by the system for battery consumption, which may lead to termination. Users are advised to check their device settings for power-saving options to mitigate frequent app closures.

Various settings are available through the application, including fixed portrait or landscape orientations, sensor-controlled rotations, and specialized orientations like lie left, lie right, and headstand. However, users may encounter functional conflicts when using this app alongside others that display overlays, potentially affecting its performance. The app's troubleshooting section suggests adjusting system settings to enable auto-rotate if facing difficulties fixing the screen orientation.
