Good point, and really just semantics. I guess you could say native mobile apps are “firmware,” using my criteria.
But I put as much effort into my mobile apps, as I did, into my firmware projects (it’s been decades since I wrote firmware, BTW. The landscape is quite different, these days -This is my first ever shipped engineering project[0]. Back then, we could still use an ICE to debug our software).
It just taught me to be very circumspect about Quality.
I do feel that any software (in any part of the stack) I write that affects moving parts, needs to be quite well-tested. I never had issues with firmware, but drivers are another matter. I've fried stuff that cost a lot.
