I'm completely deaf in my left ear, and I wear a hearing aid in my right ear. What's really cool is that my hearing aid has BlueTooth, and starting with the iPhone 5S, Apple supports direct-to-hearing-aid technology. That means when I get a phone call, it streams directly from the phone to my hearing aid -- not out of a speaker, directly to my ear. Very, very cool. Here's more info: https://www.apple.com/accessibility/ios/hearing-aids/ https://www.apple.com/accessibility/ios/hearing-aids/ That said, if I had an older hearing aid or didn't have this one, I'd definitely use this app. They are spot on about hearing loss and how it's more than just a volume thing. In fact, most of hearing loss is really an understanding thing. I can hear your voice just fine -- I just can't hear 100% of it, so the words don't make sense to me right away.
