Notice:
1.To get an accurate decibel of sound with this decibel meter (noise meter), please calibrate before use (because the performance of the microphone will be different for each device). 
2.Adjust the decibel according to your experience or calibrate with a real sound meter device for comparison. (Because we couldn't estimate the different decibel between devices, we do not provide a specific solution.)
3.To avoid unnecessary loss, please SAVE your recording before exiting the sound meter app

This app thinks my clap is louder than a rocket launch and my breath can rupture eardrums. At this point, it's not a sound meter, it’s a delusion generator. Would recommend only if you're trying to measure fictional earthquakes in your kitchen because, well... it shows it's always at 160 dB when my microphone can't even go past 110 dB. This is just insane. At this point. I will just play with the app. I will use another app. Or just fix this app and I will use it. Will the next update be 200 dB?

Unless you need very specific/professional measurements just get this. Make sure to calibrate it. UI is intuitive. It gives z weighting which is all i need. I can just plug the data into a computer/spreadsheet if i'm going to be doing any data analysis. And provides a way to get rid of ads for free while supporting the devs! All of the others just want to steal money from you. $3 for A weighting? So expensive. A weighting only works well for sound that isnt very loud.
