The Nucleus® Smart App

Take control of your hearing journey like never before.

Designed specifically for the Cochlear™ Nucleus® 7 Sound Processor, the Nucleus Smart App allows you to adjust your sound processor settings across a range of different environments directly from a compatible iPhone® or iPod touch.® 1

With the Nucleus Smart App, you can:

  • Monitor the status of your sound processor – View your battery life and check if your sound processor is working at a glance. Just tap the battery icon in the top right of the app.
  • Adjust your mixing ratio – When on a phone call you may want to block out surrounding noise so you can concentrate on your conversation. To do this tap ‘Audio Sources’, then ‘More’, and reduce the ‘Microphone Volume’ which is the sound transmitted from your Nucleus 7 Sound Processor microphones.
  • Find my Processor – The Nucleus Smart App can help you locate a misplaced sound processor by indicating on a map where your Nucleus 7 Sound Processor and compatible Apple device were last paired together.
  • Hearing Tracker – Monitor the number of times your coil comes off and the length of your Time in Speech. To access the Hearing Tracker, tap the menu button in the top left hand corner of the app.
