Accurate than other apps

This app is quite accurate and easy to verify with the comparison on top of different environment. I measured in a relatively quiet room, it indicated ~40dB of "Quiet room" while another app "Sound Meter" indicated ~55dB of "Noise". Free version does not allow saving records

Premium Push

Every time I open the app it prompts 15 times to buy premium and anytime i do anything it wants me to buy premium. 1/5 stars. Too pushy

Good and bad?

I downloaded a dozen of these sound pressure level meter apps. Most give obviously wildly inaccurate results like 80 dB in a quit room with no talking. Insane. This app gives nearly identical results when similtaneously running on iPhone and iPad. The results were not only almost identical but believable with quiet room readings in the 35-40 dB range.
All good.
The bad. The apps description talks about a setup or setting screen where you can calibrate the microphone. I can't find a setting screen or page anywhere.
