About this app

As you move through your day you may be exposed to challenging noise environments. In these everyday moments, actively managing your device settings can help you to hear better. Whether you need to adjust your volume, change program or switch to direct streaming of sound, the Nucleus® Smart App can help you do it quickly, easily and discreetly.

We understand you need your sound processor to be working well at all times, so you can hear your best and go about your daily activities. That’s why the Nucleus Smart App offers convenient ways to check the status of your battery, microphones and sound processor, keep track of your hearing and even find a lost processor.

With the Nucleus Smart App, you can:

- Change programs on your sound processor and activate wireless streaming
- Adjust the volume, treble/bass and sensitivity settings (if enabled by your healthcare professional) on your sound processor
- Adjust the volume of your Cochlear® True Wireless™ devices
- Locate your lost sound processor
- View your sound processor status and battery level
- Track time spent in speech and the number of coil offs

Note: To access the complete functionality of the Nucleus Smart App you will need a Cochlear Account, or you can try the app in Demo Mode.

To use the Nucleus Smart App, you first need to pair your Nucleus Sound Processor with a compatible mobile device. See in-app instructions or visit our support page www.nucleussmartapp.com.

Compatibility: For information regarding the sound processors, operating systems and devices that are compatible with the Smart Apps and support apps, visit www.cochlear.com/compatibility.

Note: Continued use of GPS running in the background can dramatically decrease battery life. The Nucleus Smart App only uses your GPS when it detects your Nucleus Sound Processor has been lost or turned off and does not constantly track your location.

This App is great! The only thing that might help it be even better is if there could be like a slider that could control the streaming volume, but even the current volume Up or Down button works very well!. Update... Still working great! although it would be helpful if it could tell me or help me with what I need to do in order to help my phone connect with my hearing aid to my TV streamer. -What if Cochlear made their own smart device?

When it works it works great. but the app keeps claiming it's not connected to my C.I even if my phone says it's connected. I try restarting my phone, turning the cochlear implant on and off and it's a hit or miss when it will connect. On top of that I feel the battery percentage for the C.I is inaccurate. I can't tell when it's going to die. it would be nice if it could warn me when it was close to 5% so I could know to change it for work.

The app is life changing when it's working. But it often says it cannot detect my devices even though the phone is streaming to them fine. Not a big deal, except that I can't change the settings on my devices if the app isn't detecting them. Ever since the recent update to Android 16, the app has been completely flaky, but so has Bluetooth on general, so I suspect it's not the app's fault.
