Fine hardware, substandard app

I’ve been using the app for about a year now, because I have to. Yes, I could push the buttons on the earpieces, but I can’t tweak the equalizer that way. Plus, counting beeps is a pretty slipshod way of tracking which program is which.

But the app. It’s the connectivity that’s the issue. I don’t remember the last time I opened the app and the hearing aids just connected. It doesn’t happen. Open the app, wait a bit. Close the app. Reopen. Usually, that does it, but not always. Sometimes, it’s close the app, disconnect Bluetooth, wait a bit, reconnect Bluetooth, try the app again. Maybe twice more. I have to start futzing with the app five minutes before I get on a call just to be sure my settings will be right and that I’ll actually be able to hear.

Hopefully the hardware has a number of good years left, but when the time comes for yet another set, if the app hasn’t improved exponentially, I’ll be switching brands. Perhaps the app developers think of this like a bad solitaire game that you can delete if you don’t care for it, but this app impacts my day to day ability to function in the world. And it impacts where thousands of dollars in future revenue will go. It’s fairly inexcusable that it’s so poor.

Developer Response ,

Hey Eric, thankyou for your feedback and I'm sorry to hear of the issues you sometimes encounter with connecting hearing aids. Some tips that may help improve connectivity: please ensure you're using the latest app version and latest iOS. Ensure location services are on, and the app can connect them. Connectivity can be weakened when the phone battery is very low. Please let me know if the problem persists.

Phone pairing makes a big difference

My app works great unless I don’t let the phone have enough time to pair to the hearing aids. If I pair the hearing aids to my phone too quickly, then the pairing isn’t strong enough for the phone to stream reliably or connect/work correctly with this app. I looked in the User Guide to my hearing aids though and when I followed the instruction for pairing (two minute pair) to the phone, I never have problems. It turns out that the pairing isn’t complete when I just see the hearing aids start to show up on the screen, that’s just the start of the pairing process, so Mfi/hearing aid pairing is not like regular Bluetooth connections on my phone. This app is so fantastic because it allows me to control my hearing aids more discretely than touching the hearing aids themselves. I love the ability to create “favorite” programs on my own, and have them geotagged so my hearing aids automatically switch to my favorite program. Thanks to this app, I also found my hearing aids once when I thought I completely lost them. My audiologist can even adjust hearing aids remotely when I can’t get in to see him! Overall this app has been such a great tool for me when I do the hearing aid pairing correctly to the the phone, otherwise I can have weird issues and connection problems with it.

What’s going on here??

I am less than 8 hours into my very first hearing aid experience and I bought into the ReSound system for its supposed integrated platform (made for iPhone). Within the first 4 hours the left hearing aid would no longer switch modes and could not be found by the phone. Had to unpair (forget this device) and re-pair through the Accessibility settings. Now I have a “1” notification on the app icon and an “!” on the My ReSound tab that won’t go away. The watch app repeatedly will not connect through the iPhone app saying “device not found”. When it does work, it seems to be ok but obviously questionable.

The devices themselves are working well- which is the main objective - hence the 3 stars. I can live with the app being flaky for the most part since I can always push the buttons on the hearing aids to change modes.

Might I make a suggestion- instead of beeps and tones, use a voice prompt instead. Beeps and tones are so 1980’s. How about “one”, “two”, “power-on”, etc. I have three modes currently programmed and I have to listen to beeps to know which mode I’m on. And if I switch modes using the app, why do I have to listen to the number of beeps to tell me the mode I’m in?? Geniuses are rarely tidy, but perhaps dig a little deeper and discover some game-changing approaches to making a serious product even more user friendly. Happy to help.
