▔▔▔▔▔
1. Due to microphone limitations on different devices the meter range is different, usually the low end of the scale cannot be achieved because of the microphone noise and the upper end of the scale is limited by the microphone distortion on high levels.

2. Devices employing AGC (Automatic Gain Control) that cannot be automatically disabled by this app will have significant measurement errors and limited range. This is not app's fault.

3. If you have measuring problems or doesn't work at all, try to disable "Use high sampling rate" in settings, restart the device and recalibrate.

4. Calibration procedure and other information can be found here:

A lot better than anything I've found It works a lot better than some other db meters I've seen on the play store, not the most accurate, but after a little fiddling with the presets I got to +/- 5db of a properly calibrated meter. I just wish there was a SPL graph. Calibration value for a xperia z3 is around 1.2

Another great app! Accurate compared to $200 digital meter, great to have on my ohone. Reviewer who complained it did not accurately show "500 dB" is an idiot, atomic bombs aren't that loud, read a book...

What a shame. I think it measures with a good range, but its no use because the readings are not recorded in a graph. The measurements are there and gone in the blink of an eye.
