WIDEX TONELINK is a free app developed by Widex AS that allows you to use your iPhone as a remote control for your hearing aids. With this app, you can conveniently adjust the key parameters of your hearing aids without the need for a separate remote control device or touching your hearing aids directly.

The TONELINK app offers a range of features that make it easy to customize your listening experience. You can change programs, adjust volume, mute and unmute your hearing aid, and even change directional focus to aid in listening.

To use the TONELINK app, you simply pair your hearing aids with your phone and follow the provided steps. It's important to note that the app uses your phone's speaker to transmit acoustic control signals for the hearing aids. Therefore, the sounds played by the phone may be audible to you and others, and some people may find them annoying. You can adjust the volume of these sounds by adjusting your phone volume to a comfortable level.

It's worth mentioning that the TONELINK app is compatible with WIDEX EVOKE hearing aids, and WIDEX is constantly adding more compatible devices. For the latest list of supported devices, you can visit their website.

Overall, WIDEX TONELINK is a convenient and user-friendly app that allows you to easily control your hearing aids with your smartphone.
