About

This application functions as a smart sound level meter, utilizing your device's microphone to measure ambient noise in decibels (dBA). It provides real-time readings on a digital screen and displays historical data through a graph. The app also shows reference noise levels and tracks minimum, average, and maximum decibel values.

Great app great UX no nonsense

Not sure I understand!

Thanks for developing this app - I want to use it to try and understand the difference between appliances before I spend. But just having the app open logs in at 42dcb am I supposed to be able to set it somehow? Or is this the ambient noise level?! Feel I need a few basic instructions built in. Thanks.

異様に大きく出る

深夜、感覚的には無音状態なのに常時43dbってことはないでしょ?
他のアプリより20db位大きく出る。信頼できない。

Response from developer

ご意見ありがとうございます! 静かな環境でも数値が出るのは、端末マイクの感度や周囲の微小なノイズ、キャリブレーション差による影響です。他のアプリとの差も同様の要因で発生することがあります。現在、精度と安定性の改善に取り組んでいます

Inaccurate

Completely inaccurate compared to genuine calibrated app like NIOSH

Orientación de pantalla

Deberían de habilitar la orientación invertida para agarrar el teléfono al revés, y así ver bien los datos mientras el micrófono apunta a la fuente.
