Comments on Sound Meter for Android

★★★★★ Mandeep · Oct 6, 2026

Works marvelously, I work as sound engineer for my church, and I use this to measure the sound levels works good for me.👍

★★★★★ Gregory Maxham · Sep 23, 2026

Easy to use. Great tool for peace of mind in noisy environments, like my listening room;)

★★★★★ Julian McCracken · Oct 12, 2026

I only needed a basic meter & this works very well.

★★★★★ Nicola Smith · Aug 22, 2026

Great use it all the time to measure the sound volume. So great to make sure if volume is too loud

★☆☆☆☆ Tilman Jeske · Sep 7, 2026

Doesn't work. The readings are meaningless. Android is just not able to measure the loudness.

★☆☆☆☆ Jude Rodrigues · Oct 1, 2026

Very bad experience, there is a train noise in the room, and other noises and the app is not able to record these signals.

★☆☆☆☆ M H · Oct 5, 2026

Why would this need to record my data and pass it on to third parties?

★☆☆☆☆ Zartu · Sep 14, 2026

I think this is one of the worst "sound meter" I have used. The dB measurements, is much lower than is actually is.
