I recently purchased a set of Signa Pure 13 7Nx S HA’s. At least partly because they are certified to work with the iPhone iOS. Signia provides an app thru the App Store called myControl to provide more flexible control of the HA.
I am using the app and while it seems to work pretty well most of the time, I can see room for improvement. The App Store reviews also reflect some dissatisfaction. I currently have an avenue to submit suggestions to the app development team. I you are using the myControl app and have suggestions, please reply to this thread. I will forward all suggestions.
I am currently using myControl App Version 22.214.171.1247
