>"Dumbphone" >installs e-reader apps, password apps, ridehailing/rental apps, music apps, gym apps, dev apps, home apps, "Your Internet Provider" apps (?) ??? I get that some of these are essential, but including home automation and gym apps is really pushing the definition of a "dumb phone". It just sounds like the author wants to avoid installing tiktok and games when he's talking about a "dumb phone".
I'd argue you can just stick to default iPhone apps and be fine.
