Is the My Phonak hearing aid app completely accessible?

Hi, me again! So, after playing with the Otican Intent Ones for a few days, I've decided not to keep them. The Made For iPhone compatibility is a bit of a joke with a pretty poor connection. I understand that Bluetooth LE Audio is far better but I don't have a device that uses that. On top of this, music sounds bad through speakers, has a strange tremolo effect due to the processing and the app on IOS is pretty inaccessible beyond the very basic controls. I did read on a reddit post that the Phonak app is completely accessible, but wanted to check before I dived down another rabbit hole. As Phonak use classic Bluetooth, I'm hoping the connection will be more reliable and not drop out or distort. I know it's not going to be any where near as good as AirPods, but I do need some clarity and, for three grand, I expect a certain level of performance and quality of features. Aside from that, they were good. I did enjoy the clearer top ends, it just isn't a big enough difference to warrant the cost.
