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 Sound Processor using the GPS functionality that tells you the last location where the sound processor had contact with your compatible smartphone.

Another feature on 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 to understand and monitor how your loved one is using their device.

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