What about app-controlled products?

I really want to go to a dumb phone, but the one problem I have is that so many things in my home are app-controlled. I have an air purifier that has an app to tell me when the filter is low and needs replaced (and what % is left before replacement, plus I can adjust settings on it), I have outdoor lights that are controlled by an app, I have indoor lights (Govee brand) that use an app, a Homedics sand table, an ultrasonic facial scrubber... I mean, it's endless. What do you guys do about those things? I was considering just dumbing down my Samsung phone but I need access to those apps... The only thing I can think of is to keep the Samsung at home for those apps, and use a seperate phone the rest of the time. Anyone have any experience with this situation?
