About this app

Want to measure sound level? This is smart sound level meter app for Android!
Our decibel meter uses your built-in microphone to measure sound volume in decibels (dB) and also displays samples on helpful graph.

NOTE: Microphones in most devices are aligned to human voice and the maximum values are limited by the hardware. Very loud sounds (~90 dB and more) may not be recognized. Automatic gain control used in some devices may interfere with the operation of this noise meter.

Simple to use. Hasn't fallen into the dreaded creating feature trap. It just does what it says, no more. The unabstrusive ad bar is no problem. People who expect completely free apps. are ridiculous. You should get paid for your work. I'm sure they would. Is it lab grade accuracy? I don't know, probably not. If you want lab accuracy you need to be willing to pay lab grade prices. Good job folks.

The app gives consistent decibel values when using it on my Pixel 2 XL, so the basics are solid. It's not my favorite, but I have Play Pass so I take advantage of how simple it is. 4 Stars: Considering it's not completely free, it would be nice to have some more features like logging or more control over the view. There are other completely free apps that give more detailed real-time information on the sound around you. It's consistent, so the dev certainly has an accurate start to build on.

Very good. This is the 3rd one I installed and it's a keeper. Exactly what I needed. Update...the meter still works well, but ads pop up every few minutes and the only way to get rid of them is to close out of the app (or just wait for them to play) It's very annoying and I'll be looking for another app
