App’s not ready for prime time

Every time I open the app, it has to reconnect to the hearing aids. Often times, that doesn’t work, and I need to restart the app. The connection to the Apple Watch is useless. Even when I launch the app first on my phone and have my phone right next to the watch, I rarely can connect. Defeats the purpose of the desire to discretely adjust settings when in public. The hearing aids hijack my hands-free system in my car, too. ReSound’s customer service is sorely lacking. My audiologist told me to call ReSound with my questions; the person who handled my call told me to talk to my audiologist or the Apple store (talk about a runaround). I then tried to reach ReSound through their Facebook page, and they didn’t even respond. The Apple store tried to help, but were not able to improve on any of the challenges I experience with this app. My audiologist bragged how ReSound hired Genius Bar employees to make this app; well, I think they picked up some “geniuses” at some “bar” who had had a few too many. Seriously, not everyone who wears hearing aids is a 85 year old with few technological expectations. If you’re going to promote a hearing app that’s specifically designed for an iPhone, make sure it’s going to perform as promised.

I am sorry to hear what you have experienced.
We are aware of an issue with the Bluetooth connection and latest iOS, we are therefore looking into the coding in the app in order to improve the connections.

Best regards

I bought these particular hearing aids based on the sales pitch my audiologist gave me. I was impressed with what I was told they were capable of doing: automatically connecting to my phone giving me discreet ability to control settings, changing between iPhone and iPad without glitches, and the watch!!! Wow! The watch was the “Sign me up moment!” HOWEVER... Nothing promised was delivered! Connecting to my iPhone is hit and miss, even after purchasing a new phone. I’m constantly having to reboot while crossing my fingers the 2nd, 3rd, 4th time before finally having to sometimes just give up. Switching between iPhone and iPad is just as difficult so I don’t bother even having the app on my iPad. And the watch!!! Really!!! This was the selling point for me. Of course once I realized this was an issue on ReSounds end, my trial period was up. I was looking forward to going on runs while wearing my hearing aids, but this isn’t happening. I wish I would have read these reviews and did more research before buying these hearing aids. I do regret this very expensive out of pocket expense and recommend to everyone to do their research before making this purchase.

Definitely the best of the bunch

Compared to a couple other brands, this app provides the best functionality on my iPhone, iPad and Apple Watch. Thank you. I appreciated the demo mode before I had a trial LinX 3D pair of hearing aids, and am now using this app with my new purchased Quattro’s on all three Apple Devices.

Upon occasion when I change program via my Apple Watch 4, it appears on the watch like the new program is operational (with no error message or failure indication), but the iPhone app and Quattros have not changed. This problem may happen more when the iPhone has lost or poor Bluetooth connection to the Quattros, e.g. when the iPhone is in an adjacent room but Watch remains on my wrist.

Create complications for new Apple Watch 4 Infograph and Infograph Modular faces (present complication won’t work on these).
Make Apple Watch force touch on the running program be a single press to toggle mute on or off, vs now needing a force touch then light touch to accomplish the same.
Similarly, add force touch to the running program on the iPhone app to toggle mute/unmute. This would be even easier than touching the small mute icon, and be consistent with the Apple Watch UI.
Allow sound enhancer settings for phone call and streaming to be retained and managed independently of the program in use, or describe the present design choice better in your documentation so these capabilities can be better understood and utilized.
