### ***** "Very good App"
Useful for analysis of my house noise!
-- PBotinas, 2023-12-16

### *---- "Subscrição"
Esta aplicação obriga a subscrição mesmo sem usar a aplicação… mesmo sem querer ….
-- Lopesmen, 2022-10-30

### *---- "Cuidado"
App de subscrição periódica paga e automaticamente renovada após terceiro dia, directamente na conta iTunes.
-- MickeyBlue21, 2021-01-11

### *---- "Does say that you have to pay a subscription to use"
The price should be mentioned in the add before downloading the app
-- plobbie, 2020-08-28

### *---- "Beware of hidden automatic subscription"
This is a subscription bait scheme, do not install
-- pjrml, 2020-05-16

### *---- "Uninstalling"
There is no information about the 3 days free and the monthly cost. Transparency needed
-- zhcp51, 2020-05-02

### *---- "Not free."
Useless download for a 3 day trial and you have to subscribe to use the trial. Uninstalling.

Parece uma app dispensável, mas é incrivel a quantidade de ruido que nos atinge. Com esta app posso demonstrar que estão a fazer muito barulho. Seria bom poder guardar dados com nome e data, e avaliar o volume a que se ouve musica, mas é pedir demais.
