Great App for improving and protecting your hearing.

I am a singer with the band having their amps behind me and monitors in front of me. My hearing was taking a downturn. I searched the internet for something that would help my hearing and ran across an article on this app. I have used this app for about 2 months now and have been very happy with it. As with all new apps, there have been a few glitches. The graphs didn’t work. Some of the music in my playlist could not play through this app. But the use of the app for protecting and improving my hearing, worked flawlessly! I used the app everyday for over a month and really saw an improvement in my hearing. I use it now every few days to maintain and protect my hearing. I will try the graphs in the next few days to see if this update has addressed that issue. This is a great app. Keep improving and expanding its uses.

Not sure what to think of this app yet

Wonder if it is gimmicky. Been trying for it for sometime and trying to see if it makes a difference. So far haven’t seen a difference but will continue. Don’t like it that it is a paid subscription and not that cheap.

Updated and lowered my rating since I found a few bugs with the app. Have sent those bugs to the company hopefully they can resolve it. But for the paid subscription would think it should be less or free if essentially we are beta’ing the app.

Update April 10, 2022. So got email from developer. App still has a few bugs and hope they can fix it soon. Updated my review from 2 to 3 since app developers seem to really want to fix their product and are receptive to feedback. But for price would think their main part of volume control should be fixed since this is main part of the therapy. Hopefully it works in future will try again once app is more stable with bugs fixed. Concept and practice seems to be easy and straight forward and hopefully it can help with hearing loss and tinnitus.

It has helped my tinnitus

I have been using the app pretty diligently for about a year now. I developed sudden tonal tinnitus at the age of 57 with a pitch of around 8,000 mhz. While I use AudioCardio every day for at least an hour, I don’t really think it has improved my hearing…though perhaps it has helped me maintain where I am. However, I do believe it has worked to calm my tinnitus significantly. There is something about those tones that seem like maybe they stimulate something in my ear/brain that decreases the tinnitus volume. There are still some days where it is louder and more distracting and I will listen to the audio cardio more on those days – and eventually it seems to quiet things down. I am appreciative of this app for sure as there aren’t many consistent ways to affect tinnitus. Thank you!
