Peace of mind with Find My Processor and Hearing Tracker

We all misplace things or forget where we put them. With the Nucleus Smart App, you can locate a lost Nucleus 7 or Kanso 2 Sound Processor using the GPS functionality that tells you the last location where the sound processor had contact with your compatible smartphone.

Another feature in the Nucleus Smart App is the Hearing Tracker. This feature provides you with direct access to important information such as time when the coil is off# and the amount of time speech is detected. For parents and carers, this helps measure that your loved one is using their device, especially when you are not with them.

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


Please seek advice from your health professional about treatments for hearing loss. Outcomes may vary, and your health professional will advise you about the factors which could affect your outcome. Always follow the directions for use. Not all products are available in all countries. Please contact your local Cochlear representative for product information.
