Anyone have leads on how to use a tablet as a controller for a Vuo composition.

I just tried Yam Display which, despite an outstanding bug request, seemed to work fine ... I can put buttons and do mouse tracking on the display. But it is tethered over USB and I'd like something wireless. I don't need to be tied to IOS, I don't really mind which tablet.

I was imagining something perhaps communicating using OSC.

I know these things can be built, but preferably looking for an existing app that allows for simple user interface design ... background image, buttons, sliders, mouse tracking and so on.

Any hints?
