This app turns iPhone into an advanced hearing aid.


1. The audio amplifier has 3 levels. Users can choose their own volume amplification level, comfortable listening.

2. Hearing Protection: Amplifying the volume can hear minute sound details, but if you enlarge any sound without limit, the loud sound can cause ear pain, dizziness, and even permanent hearing damage. This app uses advanced algorithms to enhance the lower sound while suppressing strong sound to protect your hearing.

3. Multiple Scenarios Selection: This app has a 12-band audio equalizer designed specifically for hearing aids, and provides preset six kinds of listening scenarios for conversational, music, video, and high, medium and low hearing loss. Users can also set their own scenario.

4. Microphone Selection. Currently, different models of iPhones provide 3 to 4 microphones. They are located below the phone, next to the front camera and next to the back camera. The user can select the microphone towards the sound source to get a clearer sound.

5. Recall function. It buffers the past five minutes sound for recall. The function is like the black box of air plane. You can get back the past conversation if it is necessary. Or save it to an audio file as a keeper.

6. A professional sound recorder is attached.

7. Support Bluetooth and wire headphone.

8. Can run parallel with music or game apps. Even if you listen to music, watch videos, play games, you can listen to the sound of environment.

9. High-quality sample rate. Use the sample rate of the CD quality to make the sound details perfectly present.

10. Noise Reduction. Turning noise reduction on will effectively reduce environmental noise and make the sound clearer and purer.

11. Support sound balance. Users can adjust the volume for 2 ears individually.

12. Can run in the background and very low energy consumption. Even if the screen is locked, the software can be used normally.

13. 7-day free trial

Subscription Problems, Developer non response

I tried this app and even signed up for annual subscription. Then the app kept messaging me while using it that I’d need to get subscription to use the various functions of the app. I was subscribing according to the Apple store. After going back and forth I finally unsubscribed with Apple since I couldn’t use the apps functions. Getting no responce from the seller was a definite negative! I’ll give the app 3 stars as it seemed to work for awhile. I was still learning the features when the suscrption issues arose.

Developer Response ,

Sorry for the problem. Sometimes, unstable network environment leads to some issues. However,you can use the restore function to get the subscription back.

I am happy with this app.

This app works for me. For example, it is great for watching TV or at the cinema. It also is useful while riding in the car if I am not able to see my companion’s face while driving or riding.
There is a delay in audio if in close proximity to a companion in conversational speech, so it is not good in this case; however it is good for environmental advantages as mentioned above.
I am happy that I purchased it and have recommended it to my hearing impaired friends.
