- Activate audio streaming on compatible Android devices (see Compatibility section below)
- Adjust the volume, treble/bass and sensitivity settings (if enabled by your healthcare professional) on your Nucleus 7 Sound Processor
- Adjust the volume of your Cochlear True Wireless™ devices

- Track time in spent in speech and number of coil offs

Note: To access the complete functionality of the Nucleus Smart App you will need a Cochlear Account, or you can try the app in Demo Mode.
To use the Nucleus Smart App, you first need to pair your Nucleus 7 Sound Processor with a compatible mobile device. See in-app instructions or visit our support page www.nucleussmartapp.com/android/pair.

Compatibility: To use the Nucleus Smart App for Android, your device will need to run Android 8 or later and support Bluetooth 4.0 and later. Audio streaming is only available on Android devices where the device manufacturer has enabled Audio Streaming for Hearing Aids (ASHA) technology. For a list of verified devices or to learn more about devices that support audio streaming visit https://www.cochlear.com/compatibility.

Note: Continued use of GPS running in the background can dramatically decrease battery life. The Nucleus Smart App only uses your GPS when it detects your Nucleus 7 Sound Processor has been lost or turned off, and does not constantly track your location.

Ratings and reviews

I have several users set up on my phone and when I switch back to the user that has the smart app installed the app reports that "Bluetooth is turned off" despite the fact that Bluetooth reconnects automatically. When I open the app it remains stuck on the "Bluetooth is turned off" message even after Bluetooth has reconnected and is working fine. The only way to get the app to work again seems to be to force stop it.

This app has always been laggy, but there aren't any other options. Every update claims "connectivity improvements," but nothing actually changes. It’s arguably worse now. I have to toggle the app on and off several times in a row just to get it to see my processors, even though they’re connected to my phone. One restart used to be enough, but now it takes a few tries. It feels like the devs don't even use or test their app on Android.

After update on 4/12/26 this app no longer recognizes my Kanso 2. Can't connect Nucleus App. I need tito to the Nucleus app to able to stream to phone so I can do my job. Horrible after update. I contacted Cochlear America, they can't fix something that is Nucleus App related because it's not my devices, my device are fine.
