*** Important ***
A lot of people report the app as broken because it does not work when auto-rotate (system setting) is enabled. This is a feature and not a bug! The app will not interfere with auto-rotate, or even lock the screen rotation for you. It observes the auto-rotate system setting and only displays the button when the setting is disabled by you.
******************

This little app runs a service in the background that monitors your phone's orientation and triggers an unobtrusive button when the phone's orientation is changed by 90 degrees (and the screen rotation is locked).
If you press the button, the screen rotation is adjusted. Otherwise, nothing happens.
A very quick and easy way to control your screen rotation on the go without having to adjust any settings.

Please note: Apps (like launchers, for example) can have app-specific rotation preferences. These are currently not overriden by this service.
Additional features may be added in the futures and can be requested.

Thanks for trying my app!
