Hearing help is a powerful program that is intended as a hearing aid as well as for ear training. Hearing help strengthens the microphone signal of an iPhone, iPod touch or iPad and processes it in a way that individual hearing deficiencies are corrected as best as possible. For this purpose, hearing help includes the following modules:

* 16-band filter audiogram according to DIN EN ISO 8253
* 16-band equalizer + / - 15 dB
* Frequency band choke to avoid listening fatigue and hearing loss at overdriven frequencies
* Dynamic compressor to avoid listening fatigue and hearing loss due to a high volume because of e.g. sound events close to the microphone
* Real-time noise filter to reduce the noise such as from the iPod's microphone

The sound processing is done almost in real time without disturbing echo formation.

The filtering is absolutely linear phase using a modified proprietary algorithm (patent DE4224842A1, Peer Dahl).

For any questions please feel free to contact us and download the manuals from the support site. You are welcome!

(Hint for Bluetooth users: The quality strongly depends on the BT devices. Good wired headsets are often preferred.)

Please note before purchasing:
The app does all that is described above - not less and not more. Please do not purchase it if you do not agree with those properties.

Will not open on my iPad.

Won't open . Using iPad with 10.3.3 it just flashes up then goes instantly to home screen.


potential but it doesnt work as properly

well it doesnt work..

I like the whole concept it has alot frequencies alot apps do not offer even a way to isolate certain sounds but to be honest at the main menu it says it paired my bluetooth headphones it did not pair it went automatically on itouch speakers..

it would be alot useful to give u guys better feedback if the bluetooth worked properly. Also for the asking price of 7.99 is far off it lacks features such as recorder with built in folders to keep them organize and a better interface as well.

otherwise I will be asking for a refund cause this item does not work as advertise I was surprised it has alot potential.


Does not work ios 10.3.2

Does not open screen flashes black and then back to home screen

Hello Slipacre,

thank you for your hint about this issue when running the app on iOS 10.3.2. This should be solved with the new version 1.42.

Could you please confirm this? Thank you very much!
