Rotation control that allows you to set the orientation of each app individually
This is the only app on the Play Store that actually does what it's supposed to. It allows you to properly change the orientation of any app to any direction and also has full auto-rotation options. It does it correctly regardless whether the target app supports it or not. Everything is automated and there's no need to press any widgets.
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.
It's recommended that you try out the free trial version before purchasing this app.
