Best App And Software Headless

Wondering what everybody uses to control a headless Windows 10 PC, and controlling with iPad Air?

Im using the app RD Connect on iOS devices and also from my MAC works well

Teamviewer for me. It’s a bit fiddly on an ipad with swipes and long-press etc but PC-PC is excellent.

I use it for all family-PC Doctor issues as well as getting into my Roon-NUC when not sat with it.

I’ve been using VNC for years.
