It was trivial for me to choose a couple of different local credit unions instead of any bank. I don't need any app, but their apps both do work on my rooted lineage phones. Their websites work on my firefox with ublock origin on linux.
A long time ago when I was young and not yet thoughtful I had a variety of regular big name banks like Citi and BofA etc.
It was the easiest thing in the world to just choose a different one that works for me.
