If this fails then restart your phone. You should restart your phone at least once a week but most people don’t. Check and see that you have the latest app update and phone update. SigniaApp itself has all the basics with split volume, simple tone control and directional control. New, are the mask mode button and Signia Assistant which can help you make some minor adjustments to your aids on your own. I used it, an it worked.

The simple tone control is too simple. You need to have 3 bands like the Resound, Phonak or 4 bands like the Starkey. You know, bass, midrange and high. I noticed Starkey has an ultra high band.
