Now that insurance companies have gotten into the hearing aid game, these devices have gotten far more capable, expensive, and complicated to tune. What i use to adjust with a screw driver at home now requires a computer and visit to the audiologist. And so after a life time of others controlling what I could hear, I found I was horrible at relating sounds to frequencies. So now whats bass, tinny, brassy, echo, reverb? All I knew was these $6000 hearing aids were by far the most expensive and worst sounding aids of my life! This app came to my rescue! So, now rather than having to say "my wifes voice is screechy loud, the tea kettle was blowing my ears, and yet i cant hear the train", and letting my audiologist guess the frequencies. This app put me in control by giving me a visual reference of the sounds around me. No more frequency guessing. I was blown away when I found my biggest issue. Every so often my ears would "yike", I had no idea if it was sound or defective aids. Twenty minutes into using this app my ears "yoked" just as this app indicated a loud high frequency narrow band clap! I had no idea of the source of the sound but I knew exactly what I did not need to hear! Combined this app with a media player app with a capable equalizer like "EQu" you can adjust, play, and see all you can hear. I found this app easy to use and give it top ratings. My audiologist will love this thing.
