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 more information, the operating manual, the support, please refer to

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


The quality strongly depends on the Bluetooth devices. Good wired headsets are always preferred.
* Bluetooth Headsets with a Mic force the sound to be mono without left-right independent setting.
* Bluetooth causes a noticeable delay.
* Furthermore the Bluetooth sound quality and the frequency spectrum is limited to the telephone mode.
* Because of the low distance between Mic and phones in case of a Bluetooth device it can occur a feedback under circumstances.

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.

Mr JPS ,

Useless...waste of £4.99.

Loaded app to use with my wireless earbuds. Sound totally scrambled irrespective of any control adjustment.

Don’t bother!!!

Developer Response ,

Hello Mr JPS,
sorry for any inconvenience with your earbuds. Please update to the current version and have another try. The issue should be resolved. But generally it is recommended to use wired headphones because of the better sound qualitiy especially regarding the microphone and also stereo signal processing. It would be nice if you could revisit your review. Thank you, sorry again and best regards - Peer Dahl
