This is easily the best decibel meter app I've ever used. Has more useful features than all the other apps (the others all are missing one or two things, this one is comprehensive) and the ads aren't constantly popping up every 15 seconds. Only downside is the remove ad cost is a bit more than the others, but the ads aren't very intrusive so it doesn't feel as necessary.

This is the best app I have found, I'm using a Poco f7 pro and have an independent sound meter which enabled me to calibrate it. I had to add +22 which seems a lot, but once done the meter is good. Other apps I tried were closer to where they should be sound wise, but adverts or not being able to set the time interval for reading and similar things made me pick this one. Calibration is important though as some apps I tried needed to be reduced and others increased. Each phone model is different.

I installed and then had to uninstall this app. Once opened, you can't exit the app. Once opened, all the usual Android buttons and menus disappeared. I tried the usual things to exit the app. The thing that finally worked was Android's "pull-down" system menu accessed by swiping down from the very top of the screen. It was the only piece of Android's UI still accessible.
