The Ear Agent Live: Ultimate Super Hearing Aid App is an easy-to-use app that makes your smartphone or tablet into a powerful listening device.

The app lets you easily adjust the volume of the sound that is being played. It also includes a built-in equalizer that you can use to adjust the sound to your preferred level.

It is designed to be used as a hearing aid, but it can also be used for other purposes.
