### 5/5 — Great

*2020-12-29, version 2.0*

This is a great little app easy to understand and given me peace of mind in many situations. Thanks.

### 5/5 — Useful tool for citizen action

*2018-08-30, version 1.9*

I used this handy tool with easy-to-understand display to persuade a movie theater manager to lower assaultive sound levels of movie trailers. My awareness of hearing conditions was raised by a friend who suffers from hyperacousis. I’m now more proactive in protecting my hearing.

### 5/5 — Unexpected Features

*2017-04-26, version 1.9*

The encyclopedic level of information about hearing loss and hearing protection included with this app was a pleasant surprise! Want to know about the anatomy and physiology of the ear? Feel like perusing OSHA tables on decibel levels? Need a comprehensive description of hearing protection devices? Just hit the little "i" in the bottom left corner! And this cornucopia of knowledge serves a purpose: It enables you to better interpret and understand the wealth of data the app calculates. Of course, this assumes you have some familiarity with and an appreciation of apps that almost inundate you with facts and figures, and that the process of parsing such information is in your wheelhouse. If not, you may want a more simplified app.

### 1/5 — Sad!

*2017-03-27, version 1.9*

This app is very bad! Sad! I want my money back! There is no way to set a max dB level! Sad!

### 1/5 — App does not work

*2016-10-11, version 1.7*

App does not work

### 5/5 — Rating

*2016-09-21, version 1.7*

I really like this app.  It is easy to use and correlates very close with my commercial sound meter.

### 5/5 — Great app!

*2015-11-21, version 1.6*

I really like this.  Very easy to use and understand.  Helps keep my hearing in good shape.

### 5/5 — Simple and easy to use with accurate readings

*2015-11-20, version 1.6*

I have used this app for quite awhile and was disappointed when it wouldn't work on my new iPhone 6s. I contacted the author and he fixed the problem. I'm very pleased and can recommend this app to anyone who wants/needs to sample sound.

### 5/5 — Excellent App. Even Better Tech Support

*2015-11-20, version 1.6*

App works as advertised. What makes it great is the extremely helpful tech support provided by Auralware. This app has my highest recommendation.

### 1/5 — Crap!

*2015-11-12, version 1.5*

Fix for ios9 please!
