This is not realistic. If each app takes only 1min of my time, that would sum to 30-100 mins. who has this much free time?

Right now I usually only use 13 or so apps of my phone, like a dictionary, a map, a mail, a search engine, 3 socials, 4 language apps, camera, music.

And they take most of my screen time.

But a lot more apps are running in the background that manage things without my interaction. If by clients you mean those , sure, maybe.
