### 1/5 — App not working

*2026-06-26, version 4.8*

Just purchased the app … not working at all!

### 1/5 — No tiene una guía de uso

*2025-03-17, version 4.8*

No me gusta para nada no te explica cómo usarlo

### 1/5 — Muy simplona!

*2024-03-29, version 4.8*

Son los 39 pesos peor gastados hasta ahora, piénsenlo mucho si van a invertir en esta app.

### 3/5 — Limited by Device’s Mic

*2023-07-27*

The mics on these devices have dynamic limiters and don’t capture low frequencies. So a person relying on the built-in mic to capture dB levels, will NOT get accurates readings for loud or bass-heavy sounds.

### 5/5 — Awesome Audio Levels App!!!

*2023-01-15*

Works great for ambient noise levels including highest and lowest levels indicators and recording ability for later playback.

### 5/5 — Useful tool

*2022-12-05, version 4.8*

A useful App.

Looks interesting. Useful to see the levels. Had to think for two seconds about how to record, and delete file. Will review again shortly.

### 5/5 — Macht einen guten Eindruck

*2022-12-01*

Ich kann die schlechten Bewertungen nicht nachvollziehen. Man muss halt wissen, dass man das Meter antippen muss, damit die Messung los geht. Ansonsten kein Hexenwerk, tut was es soll.
Was ich aber großartig finde, ist, dass die App aus datenschutzrechtlichen Gründen absolut unbedenklich ist, da sie keinerlei Daten sammelt oder übermittelt. Eine Seltenheit!

### 5/5 — 気に入りました！

*2022-11-16*

アプリの反応も素早く、視覚的にも見やすく 優れもものアプリだと思う。

### 1/5 — Nutzlos

*2022-09-01*

Die App ist absoluter Schwachsinn, es werden auch nach mehrmaligen zurücksetzen im leisen Zimmer ca 67 db angezeigt was viel zu laut wäre. 
Aber bei meinem Auto misst es 102 im leerlauf und wenn ich Gas gebe und er richtig knallt gehts runter auf 60db. 
Kauft eich die App nicht, da die Kostenlosen kein bisschen schlechter sind.

### 5/5 — 使いやすい

*2022-05-05*

サンプル周波数も選べるし、ろくお
