Hi there.
There is a specific ZerOS Monitor app that was produced for Windows. There is also a MacOS version if you prefer.
However, there was not a ZerOS Remote app produced for Windows for public use (to my knowledge, I saw Edward using ZerOS Remote on Windows in a training video).
Anyhow, ZerOS Monitor on a laptop or desktop does function as a sort of "remote", as it allows for keyboard shortcuts to be entered, such as R for record or U for update.
They are downloadable at the links below provided by the ZerOS Software page on Vari-Lite's website.

For Android, you can of course use the APK files listed in the thread, kindly provided by kgallen.
