Comments on Sound Meter for Android

★★★★★ John Daniel II · Jul 5, 2026

Does its job. Gives you a decent reference of sound level. It's not a reference quality measurement, but it's a good ballpark reference.

★★★★★ Gary O'Hern · Aug 12, 2026

Wanted to verify noise levels were below hearing protection ranges. This app helped us determine what was required.

★★★★★ Doug Guthrie · Jul 15, 2026

It is very accurate, easy to use, I use it to check sound levels of my hot rods

★★★★☆ N vdP · Aug 5, 2026

It's easy to use, simple to understand and works pretty well.

★☆☆☆☆ Marharols · Jul 30, 2026

300 different services do not need my data for a decibel measure, It's also a breach of EU law not allowing consumers to easily select no to all.

★☆☆☆☆ Paul Edwards · Aug 18, 2026

Fake virus message appears when adjusting app colors. Avoid

★☆☆☆☆ Jezz Smith · Jul 24, 2026

I only needed to tap inside the app twice before a full page cancellable ad appeared. I will now uninstall this utter garbage.

★☆☆☆☆ Sumanus Telefonas · Jul 27, 2026

Im standing in front of fire alarm, and it shows 40db quiet library
