When connected to your phone by Bluetooth, your hearing aids will send activity data to the app every 15 minutes. Your hearing aids should be connected to the app at least once a day, since data is stored in the hearing aids for the last 24 hours. To connect your hearing aids to your smartphone, simply open the app and turn on your hearing aids. If your aids don’t connect, then check the Bluetooth settings on your phone to make sure your hearing aids are paired correctly.
