The ReSound Smart 3D™ app is compatible with the following hearing aids:
• ReSound LiNX Quattro™
• ReSound LiNX 3D™

The ReSound Smart 3D app lets you control your hearing aids directly from your mobile device. You can change programs, and make simple or more advanced sound adjustments and save them as favorites. The app helps you learn what you can do and how to do it. It can even help you find your hearing aids if you lose them.

Veldig bra, men ett par ting irriterer litt i det daglige

Treg oppstart og burde kunne brukes med Apple Watch uten at tlf er med

Developer Response ,


The MFi function, which the hearing aids use, are build in the phone and not the watch, this is why the hearing aids and the iWatch cannot connect without the phone.

Best regards

Very good app with a few irritating bugs.

I got new hearing aids from Resound and they have a good companion app on the iPhone. The app works well and has made my life easier and better with my hearing aid. As I can control the way the hearing aids work, it’s easy to adjust them to the environment and stay safe.

When I found the app for the Apple Watch I was thrilled. But what a mistake. It doesn’t work unless you open the iPhone and the app on the iPhone. If you close the app only or you close the iPhone it stops working!

Please fix this and it would get 5 stars, maybe, I won’t promise, maybe 4.

Get on with the work on the app!

Update 14/2/2019

Thanks for the advice it worked straight out
Great response from the app support.
5 stars treatment.

Thanks for your comment.

If you disable the MFi Optimization in the app, then will the iWatch work without having the app running on the iPhone.
