I don't carry around any Apple device, neither do most of people (including various IT folks in various banks) I know. You can't tweak its settings without one.
Fair. I was more referring to smart phones in general. The argument was “you need a $1000 device for this $200 thing”. But if other manufacturers come out with similar hearing aids, I’d expect most to work with either iOS or android and would require one of the two $1000 devices to work.
