Returns a text string indicating the operating system of the device running the app, or a blank value if the operating system is not known.
These are the values returned by this property:
iosfor Apple's iOS operating system, used by iPhone and iPad devices.
androidfor Google's Android operating system.
windowsfor Microsoft's Windows operating system.
macfor Apple's macOS operating system.
linuxfor operating systems running the Linux kernel (except for Android).

This property is a read-only property, meaning that no formula can be assigned to it.
This formula is associated with the Visible property of a text box containing instructions on how to add the app to the user's iPhone or iPad home screen. As these instructions are specific to the iOS operating system, ensuring that they only appear on iOS devices makes sense. A different text box could be present with instructions specific to Android devices, with a similar formula associated with its Visible property.
