It's nice when it works, but when I'm at a place where I most need to make adjustments, I usually can't get it to connect with my hearing aids. VERY FRUSTRATING! I have to shut off my hearing aids then turn them back on in discovery mode....several times....or even dump the app and reinstall it...to get it to connect. No luck yet today. Useless. I don't have a problem connecting hearing aids to the phone via Bluetooth for calls and media.....just connecting to this app.
