The thing is, there aren't any desktop apps—much less Linux desktop apps—for the types of things I need to do on my phone. On an Android phone, I can buy train tickets (NJTransit), deposit checks (Chase), and have telemedecine appointments with my doctor (MyChart).
I don't know if all of these would work in e.foundation, but presumably at least some would run.
Unfortunately, I chose all of those examples explicitly because they can't be done on the web—they can't be done on a desktop device at all! :(
The telemedecine app is a big one I think about. I don't know what I would have done if I hadn't had a modern iOS or Android device when the pandemic hit in March, and my doctor appointments suddenly moved to this remote system.
