Nicely done app – SoundMeter+ Review

While I have no test equipment with certified calibration for comparison, I've found the readings to match verbal descriptions of various noise levels closely, e.g., "library" or "chain saw at 3 ft". The app provides a variety of information in addition to raw dB level, including spectrum and safe exposure duration data. Controls are fairly intuitive, and the display is well thought out. If you need such an app, this one is, in my opinion, well worth getting.
