Comments on Sound Meter for Android

★★★★☆ 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.

★★★★★ Martins Jancevskis · May 1, 2026

Good for measuring and adjusting the loudness levels such as the maximum loudness of a sound system, so you don't go beyond recommended power and ruin your hearing. Set the maximum level using this and don't go beyond maximum loudness to conserve ear health.

★★★★★ kiran chandra · May 2, 2026

Good app. You can check decibels around your environment and equipments like air cooler, ac, etc

★★★★★ 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

★☆☆☆☆ Jeremy T · May 5, 2026

Professional meter reads 21 this shows 32 to 34. Same place same time right next to each other.

★★☆☆☆ Elizabeth Labuschagne · Jun 7, 2026

I'd love to have a save option where you can save a recording with the date and time

★★☆☆☆ Aaron Tippetts (ShadowFox85) · May 2, 2026

I don't mind ads but when they prevent you from using an app that you need to use at certain times, that is unacceptable don't make the add full screen, or block controls. Also, the sensitivity is 10 DB below what it should be

★☆☆☆☆ 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
