User reviews

Compatible or not??

This application specifies that it is compatible with ‘this device’ until you download it, to get a warning that it is not. What a waste of time!

Best free noise metering app

Thank you for making this app! Love it!

Huller om buller.

Mycket effektiv och lätt använd app. Att den är gratis är ju ett plus.
Som musiker med tinnitus kommer jag att ha stor användning av denna app.
Det kan också komma till pass för att visa personer med fakta om ljudnivån är skadligt hög.
Kan nog också fungera för att få ungarna att vara lite tystare när jag kan hänvisa till ljudnivå. :)
