The Nucleus Smart App is not designed for use on tablets.


The Nucleus Smart App can be downloaded for free from the Google Play Store. Tap the Play Store icon, search for 'Nucleus Smart', and then select to download the Nucleus Smart App. Please be aware that the Nucleus Smart App may not be available in all countries, and may therefore not appear in your search.


No. Android devices do not have built-in support for hearing devices. Therefore you need the Nucleus Smart App on your Android device if you wish to use it to control your Nucleus 7 Sound Processor.


No. You can use the Nucleus Smart App to control and monitor your Nucleus 7 Sound Processor on compatible Apple and Android devices.

"Made for iPhone" means that you can stream audio directly to your sound processor from compatible Apple devices. To stream audio from Android devices, a Cochlear Wireless Phone Clip is required.


The Android operating system does not yet support direct Bluetooth® low energy audio streaming. You can enjoy streaming phone calls and music wirelessly from your Android device to your Nucleus 7 Sound Processor with the Cochlear Wireless Phone Clip.


To control your Nucleus 7 Sound Processor with the Nucleus Smart App, you will need to download the Nucleus Smart App and log in with your Cochlear Account. If you do not have a Cochlear Account, you can create an account once you have downloaded the app by tapping 'Create new account' and following the on-screen instructions.


You can pair your Nucleus 7 Sound Processor with up to five compatible Android devices and have the Nucleus Smart App installed on all of them.

However, you can only connect one compatible Android device to your sound processor(s) at a time.


Yes. If you pair your compatible Android device with your child's Nucleus 7 Sound Processor, you can control and monitor the processor, which allows you to see battery status, adjust volume and change program without needing to touch the sound processor.


If you are unable to adjust your sound processor(s) using the Nucleus Smart App, your compatible Android device may not have been paired properly with your processor.

To learn more about the pairing process, watch our Nucleus 7 Android pairing animation. If you have successfully completed the pairing process, ensure that your device is within the recommended range, and that there is nothing causing excessive interference. If the problem persists, contact Cochlear or your hearing health professional.


In the top right of the Nucleus Smart App home screen, you will see a battery icon. This will indicate how full your batteries are. Tap the battery icon to see the 'Status' screen which shows more detailed view of the sound processor battery level. This screen also illustrates the sound level being delivered to your Nucleus 7 Sound Processor, and the sound processor status indicator. A tick indicates that your Nucleus 7 Sound Processor is working properly.


If you have completed the pairing process, you can swipe down the notification shade and check that the Nucleus Smart App is displaying the battery status of your processor(s). If you do not see the notification, this means the app is not running. You can start it by finding the Nucleus Smart App icon in the app drawer (or on your home screen) and tapping it.


The Nucleus Smart App will only stop running if you force the app to close. You should only close the app for troubleshooting purposes, as the app must be running to utilise features like "Find My Processor" and "Hearing Tracker". To close the app, open Settings, select Apps, find Nucleus Smart in the list and press "Force stop".


If you received your Nucleus 7 Sound Processor prior to July 2018, your sound processor firmware will need to be updated before you can use it with an Android device. This simple update can be carried out by your clinician. Contact Cochlear or your hearing health professional for more information.
