Funny, that is a single physical button on my Siemens dishwasher.
Sure, there's one on my Bosch too. But I'm damned if I know how to set it to (for instance) turn on at 7am by using the buttons on the machine. There's probably a way involving multiple button presses. The app does that easily.
But as I said before - not really something I care about either way.
