@czarnowski. I don’t know what your current hearing aids are or what you have been recommended.
However, I will make a comparison which I hope will be similar.
My old Phonak Naida V90 UP’s have two sets of switches, one (rocker) for volume and the other (button) for program switching/cycling, and there for didn’t need and app to control things.
My New Phonak Naida P90 UP’s however, only have the up/down rocker to change volume and then long press to change programs, a bit annoying. For me, the APP has been awesome, I can make very quick changes to any program I want, or make changes to some program setting that can only be done otherwise with the Target Software. Like narrowing the focus of my hearing when I’m in loud places to better hear the person in front of me; changing the Bass/Mid/Treble to better pick up particular voice characteristics; Switch the hearing aid mics off, so I can better focus on the audio in my Roger On Mic.
Last but not the lease, without direct streaming of phone calls into my new hearing aids, I really struggle to understand any conversation on the phone, telling people to text me don’t ring (in the past).
As in another of my posts, I have had to send my new HA’s in for repair, and I am back struggling and miss all my new functionality that I have with the APP.
That my 2c and only an opinion as a technology geek.
