Comments on Sound Meter for Android

★★★★★ Tommy Meissner · May 13, 2026

it's a sound meter. I use it in church to gauge if the choir sings loud enough. And to prove to my wife that children noise exceeds safe thresholds

★★★★★ 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.

★★★★☆ Allan White · May 22, 2026

Works and good for comparison at diff distance. Problem is I get different results from different phones, as much as 20db. Would be good if there was a way to calibrate. I was measuring generator sound at diff distance.

★★★★★ DAVID · Jun 28, 2026

THIS APPLICATION IS WELL ORDERED...NICE GRAPHICS AND VERY ACCURATE ... HAVE ENJOYED ITS USE AS IT DEFINITELY RATES ALL SOUNDS WITH PRECISE NUMBERS.ALSO YA CSN RECALIBRATE IT TOO. EXCELLENT PERFORMER 👍

★★★★★ Ayush man · Jun 8, 2026

Five stars. This is a very good app, and it detects sound almost perfectly I guess. It is user-friendly and easy to understand. It also shows the chart 📈📉 of the decibel meter. Overall, this is one of the apps I have ever rated. I rate only if I think it is actually good.

★☆☆☆☆ Amy Martinez · Jun 8, 2026

Completely inaccurate.first of all it starts recording immediately, so it catches things you didn't want it to catch. Secondly it picks up way too much, to the point where background movement blocks out larger sounds that you are trying to measure. Needed this for a project and it was garbage

★★☆☆☆ Steve JB · Jun 19, 2026

Suspicious of some ads that appear. I was shown an ad for something called ‘Cyber Scan’ (or similar). The ad had a white background, turquoise buttons and was displayed like a security scan. It also displayed two different ‘close ad’ (x) buttons — both in a similar position. The combination of the fake‑security style layout and the apparent mimicking close button made me uncomfortable. Quickly uninstalled Sound Meter after
