It will detect the launch and close of your apps, and allow you to automatically change to the orientation (direction of the screen) you set for each app.

Even apps that have a fixed vertical screen orientation even if you tilt your device, such as home apps and launcher apps, can be displayed in a horizontal orientation.


Rotation

Automatic : the screen rotates based on a sensor.
Landscape : the screen is fixed to a horizontal orientation.
Landscape (Reverse) : the screen is fixed horizontal upside down.
Portrait : the screen is fixed to a vertical orientation.
Portrait (Reverse) : the screen is fixed vertical upside down.


【For OPPO users】
This app needs to run a service in the background to detect which app has started.
OPPO devices require special settings to operate app services in the background due to their unique specifications. (If you do not do this, services running in the background will be forcibly terminated, and the app will not operate properly.)
Please drag this app a little down from the recent apps history and lock it.
If you do not know how to set, please search for "OPPO task lock".
