## What is HearingZoom?

This app transforms your phone into a pair of hearing aids, one for each ear. You will need to use a headset. The app amplifies ambient sounds like a typical hearing aid, plays and amplifies musics stored in your phone. 

The app can also test your hearing and automatically calculate the amplification for your hearing level. 

You can further adjust the amplification. Your adjustments can be saved as a program. You may save as many programs as you want. You can load a saved program using at any time.

In order to get the best out of the app, it is recommended to use AirPod Pro or a pair of wired headphones or earphones. If you need a lot of amplification, headphones/earphones with active noise cancellation would afford you a best listening experience. 

If you use a bluetooth headset, you can use your phone as a remote mic and place it near the person you want to hear clearly.

### 5/5 — This app works! And it’s free!

*2024-08-01*

What do you have to lose? I turn this on and put it on the table close to my friends while we are playing cards and I can hear everything. Take the test and save it. (I sat in my car with the windows rolled up so there would be no noise to interfere with the beeps.) Afterwards, compare it to the one named DEFAULT and you will see it really works pretty well. It matches my audiogram from my hearing test. My audiogram says I can hear better the low frequencies and this app’s test results show, with the white dot, that it doesn’t need to amplify the low frequencies. Same for the middle and high frequencies, my audiogram showed I need lots of amplification and this app also shows that by the white dots for those frequencies being higher on the chart. Then take the test in different locations that have different types of noise and save them also. I haven’t done that yet but I think it will help when I’m out to dinner in a noisy restaurant.

### 5/5 — 5 Star

*2023-05-01*

This is the best noise filter free free free listening hearing aid app on the market

### 1/5 — Works with new OS?

*2022-04-19*

I have had this app since my iPhone 6 and it’s never lost connection between the air pods until this new OS came out and all of sudden your listening to something important and then your listening to the sounds of dead silence comes on sometimes in a few second and other times like this instance it’s still not came back on and I’ve typed this entire review and still I have turned a deaf ear to the subject I real needed to hear! So good job app I’ve lost all confidence in this I can’t ever get a shot at hearing what I missed again, people count your app it’s useful if it works but I wouldn’t become dependent on it it’s just to much to risk when you least expect it you’ll be with out ears!

### 5/5 — Excellent app

*2019-04-30*

Very nice app 
It works what it says. 
Thank you for such a great app

### 1/5 — Very crude app

*2018-09-13*

Hearing test method seems legit enough. But then when you actually USE the profile you’ve set up, you can’t adjust For L or R ear, and you only get three freq sliders (bass / mid / treble) to adjust.... and again, no adjustments for Either ear.  When you listen with your profile, you hear a TON of static and noise.

### 1/5 — Stupid update

*2017-11-01*

I wouldn’t even give this app a star if I didn’t have to because I had this app once before worked great then after deleting and then re down loading it you no longer are able to adjust the settings to your preference.

### 4/5 — Great!

*2017-07-29*

I've tried all the apps and this is the only one that works! Only one prob you cannot switch it off.

### 5/5 — Awesome free app, right when I needed it! 👍

*2017-05-23*

This app really deserved to have the 5 star or more due to it's free and it works even in a bluetooth headset. I love it for it totally worked on the bone conduction headset that I bought - for I can hear better with bone conduction. The app may just needs calibration in the echo and a mili-second delay but other than that it was awesome right when I tested it. Whoever created this I would like to thank you so much for this app of your have saved me from my meetings and other things at work and home!!! 👍😊
