I know nothing about the Apple world so take my question in that context. Is there something equivalent for iPads ?
If my wife could take control of her Father's iPad then both parties would be happier, as far as I have been able to discover this is something that isn't able to be done, by Apple software or third-party. If I found I out I was wrong that would be good.
You could start a FaceTime call, have him share his screen, and lead him through whatever he needs to do. You don't have direct control, but if he can follow directions, it'll work.
