### 2/5 — Reads 20+ Higher than Reality

*2026-08-17, version 1.0.2*

Compared to other db meter apps, this reads over 20db more noise. 
You sit in a perfectly quiet room and it reads 60+ db. 
Didn’t see a way to calibrate the app, but it sure needs one.

### 5/5 — Excellent

*2026-06-21, version 1.0.2*

Use it a lot.  Easy to use

### 2/5 — Accuracy?

*2026-06-12, version 1.0.2*

I have a room insulated from sound for listening to hifi… yet this app shows 47db as what I would consider silence; go figure

### 1/5 — Rubbish app

*2025-01-09, version 1.0.2*

Registers 60 Db in a totally quiet room. Any additional noice barely makes any difference.

### 4/5 — Pretty close to my actual decibel meter…

*2025-01-05, version 1.0.2*

The app is convenient, and gives readings inline with my stand alone decibel meter…. App seems to be about 4-6 dB higher than my meter.

### 1/5 — Pas très précis

*2024-07-15, version 1.0.2*

Il indique le double de mon sonomètre alors non passé à mieux

### 1/5 — Stealing Clipboard

*2020-11-14, version 1.0.2*

Be careful, this app steals the clipboard!

### 1/5 — Junk

*2020-08-05, version 1.0.2*

Inaccurate by 25 dB, no way to calibrate. Waste of time.

### 5/5 — Applicazione gratuita

*2020-07-11*

Con pubblicita non fastidiose
Funziona bene

### 3/5 — 30db above Apple Watch!

*2020-06-16, version 1.0.2*

App on iPhone 11 Pro Max is reading 30db above Apple Watch v4 !!
