Using Threshold Sound Conditioning™ technology (TSC), our sound therapy stimulates the inner ear cells to target damaged hearing for each ear.

TSC technology was clinically proven with:

Stanford Univ.

• Sound therapy that aims to help maintain, protect and strengthen hearing
• Fast hearing check that creates a personalized sound therapy for your ears
• Generates hearing score, usage metrics and identifies targeted frequencies for each ear
• Integrates with music, streaming services and other daily activities

Allows you to test hearing, create a personalized sound therapy, track progress for each ear and can be used as a complementary solution to your hearing aid (s).

This is not a clinical hearing test, but it is a great way to do an initial hearing screening to better understand your hearing loss, promote better ear health, and healthy hearing habits.

Over 450M people suffer from hearing loss and over 300M people suffer from tinnitus or ringing in the ears. Tinnitus can be a symptom of hearing loss and hearing loss is a problem that often goes undiagnosed. It is known as an invisible disease / disability. Current solutions like hearing aids are hard to access or too expensive for a majority of the population with hearing loss. This may be why people wait an average of 7 years before they get a hearing test from a hearing health professional.

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.

No reverse slope treatment available

Wanted to try this app for myself after failing to find much in the way of medical professional endorsement and no current research or clinical trials regarding the product. While it may work, the app does not offer any tests or treatment for hearing deficiencies below 1khz, which is the only significant hearing loss I have been subject to, and the only reason I am interested in this app at all, and as such it is utterly useless for treating my deficiencies.

Furthermore, there are issues with the audio test it provides, even considering the disclaimer the app provides. First and foremost, the app does not allow for the input of a professionally administered audiogram test. This is likely due to the app not even attempting to correct for different headphone’s unique frequency response (no headphone in existence provides an audibly flat response), which would most definitely result in inaccurate results that could be much more accurate (though not perfect) with little additional effort.

In its current state, the app seems incomplete, and inadequately vetted by research into the efficacy of the product at hand or third party verification that the app does not peddle a placebo through some software trickery users may not be able to identify.

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
