### 2/5 — It works but....

*2020-02-16, version 2.0.2*

YOU HAVE TOO FREAKING PAY TO SIMPLY   CHANGE  A FREAKING COLOUR!

### 2/5 — Crashes on export

*2017-04-10, version 2.0.1*

I upgraded to pro specifically to be able to export to CSV but it crashes every time I try to use it. Totally useless to me. Please fix the bug or refund me.

### 1/5 — Useless

*2015-04-10, version 1.0.2*

When will Apple learn, what's the point of putting an app it's site that just don't work? Useless!!! Take these useless things off and stop wasting people's time.

### 2/5 — Spoilt by adds

*2013-06-02, version 1.0.2*

Ticka adds across the top spoil a handy app.

### 1/5 — No furula!

*2013-04-30, version 1.0.2*

Por más que le intente al demo no opero, parece solo gancho para el pro.

### 1/5 — Lot's of lag time, not very accurate.

*2012-12-11*

Used this meter while chaperoning a high school dance. It did not work very well. As a physicist I also had an Extech dedicated meter. This app never matched the Extech.  Even with obvious changes in loudness (song stopped) the meter did not change its reading. 

Downloaded Decibel 10th and it worked much better.

### 1/5 — NG

*2012-12-11, version 1.0.2*

My doctor told me to use it seemed to work for TWO times that's all 
I will delete it and look else where

### 3/5 — Good but...

*2012-02-07, version 1.0.2*

Previous version worked ok. It was not too accurate but gave good guidance. Sadly the latest version crashes immediately on opening. This is an iOS3x vs iOS4x fault. It needs the coding tweeking for older systems - please?

### 1/5 — Witz

*2011-12-22, version 1.0.1*

Dieser app ist ein echt schlechter scherz...es zeigt bereits bei niederem geräuschpegel 70db an ...

### 3/5 — Worked fine

*2011-12-20*

It was fine for me,  it worked fine and was accurate, but it takes up so much space that I had to delete it.
