Made for iPhone, First for Android

The Cochlear™ Nucleus® 7 Sound Processor is the only cochlear implant sound processor with built-in technology that lets you stream sound directly from a compatible Apple or Android™ device* — without the need for any attachments to the sound processor.

This means that you can stream your favourite movies, TV shows, music and more directly to your sound processor without sacrificing size, comfort or battery life.

Convenient control with the Nucleus Smart App

The Nucleus® Smart App is designed specifically for the Nucleus 7 Sound Processor to provide you with a convenient and easy way to tailor your hearing to your personal preferences — all from your compatible Apple or Android smartphone* or Apple Watch®^.

With the Nucleus Smart App, you can:

  • access personalised hearing information with the Hearing Tracker

  • change programmes or volume and check battery life without carrying a separate Remote Control

  • get help finding your sound processor if you misplace it

  • start wireless streaming to your Cochlear™ True Wireless™ devices

  • fine tune your hearing experience by adjusting Master Volume, Base and Treble

  • set up notifications to alert you if the coil is off.

To experience all the features of the Nucleus Smart App, download for free via the Apple App Store or the Google Play store.

How Find My Processor and Hearing Tracker may help

Many of us misplace things or forget where we put them. With the Nucleus® Smart App, you may be able to locate a missing Nucleus® 7 Sound Processor using the GPS functionality that tells you the last location the sound processor had contact with your compatible smartphone.

Another feature on the Nucleus Smart App is the Hearing Tracker. This feature provides an adult or child with direct access to important information such as time when the coil is off# and the time in speech. For parents, this helps measure if their loved one is hearing, especially when they're not with them.

The Hearing Tracker information, along with the built-in data logging functionality of the sound processor, helps your audiologist troubleshoot and make adjustments.
