Worthless to me
PCRHKR
I play most of my music off my iPhone. I cannot run this application at the same time that I'm play my MP3s! What's with that? How do I play my MP3s and know the decibel level? You can't with this application.
Great free app

The DEP was just here in my apartment in NYC measuring sound with a $3000 sound meter. I tested three apps concurrently and this one was the most accurate.

Excellent app. Easy to use and it gave uniform dBA readings when compared to other decibel recorders.
well-designed and accurate

I'm an acoustical consultant, and tried out a few free sound level meter apps. This was the best I tried because it offers A, C and Flat weightings, calibration, fast and slow response, min, average, max and Leq levels. Nice job on this useful app.
Lite

I tried to use this app and it was impossible because of the ads covering up part of the screen. I deleted it.
Does not record sound actively
Nickname choices
I tried this out in a very noisy environment and it did not register any sound. There are no instructions or settings that I could find. I assume it does not work with my iphone 5s.
Crashes on iPhone X
gzerninplatz
Crashes back to iOS when starting to listen on iPhone X Deleted and reloaded app, still crashes That’s all I have to say, this used to be a great app.
Auto rotate gone, up 4 steps back
Jodiuh
Ability to auto rotate gone. To see the screen and point the mic is not possible any longer. UI looks much worse.
