AudioCardio™ is a sound wave therapy that aims to protect, maintain and strengthen your natural hearing ability. It's like physical therapy for your hearing.

It's a once a day, one hour, barely audible therapy that you can use with or without music so you can enjoy other activities while you use the therapy.

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.

App does not work

This app stopped working just short of a month of use. I subscribed to access the TSC feature, but before the month was over, the app would not let me access that feature. I uninstalled and reinstalled a couple of times, but that did not work. My subscription renewal was two weeks away. I emailed the app support, but never received a response. I don’t think the app ever was fully functional, but the TSC feature was good. Unfortunately, the app stopped working so I cancelled my subscription.

Update - I was contacted directly by the app developer to address the problems I was having. They listened and fixed the issues with the app and it’s working great now! I’ve revised my rating to reflect the app and the customer service I received. Thank you!

Developer Response ,

Hi DoubleG, we apologize for the inconvenience. I believe the issue was resolved with our tech support team. Thank you for your patience and continued support - C

Minor Tinnitus/Hearing Loss Improved thru app!

I have ringing in my ears once every other day or so, and it can be really annoying and untimely. I pretty much had given up on any hope without major corrective surgery or some sort of over the counter medications, which I was unwilling to do (yet). Then I was introduced to Audio Cardio and I gotta say, although I still have a slight ringing in my ears, the frequency at which it happens has been reduced quite a bit through this app, and I’m so grateful it’s so non-intrusive and affordable! I look forward to every app update now that the company is getting dialed in to what customers want. Keep it up AC team!
