Solid little app

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.

Ben B in Burlington VT

I recently downloaded this sound level meter app and it seemed to be running continuously without my having to start recording.
Somehow, I have now stopped it operating all together. There is no obvious β€œStart/Stop” toggle or button, only a Pause/Resume (recording) option. I’ve shut down and restarted my iPhone 15 but no change. The drop down menu only has options for the 4 different sensitivity decibel readings based on the type of noise to be recorded.
At this point, I give this app one (1) Star unless I get help on instructions for operating this decibel reading app.
