Good meter

The meter is reliable for use. I used it to measure the noise in our property.

Very very good. The manual and automatic calibration features really make this app. Thank you

Ha. Wow. What a joke. This is an app that has colored lines that move around in response to sound and makes numbers. That's where the similarity to an SLP dB meter ends. It is so grossly inaccurate that it is little more than an iPhone toy/gizmo. It may be the fault of my iPhone microphone response, but IT IS MADE FOR AN IPHONE???
What they need to do is provide a calibration method that permits calibration at a minimum of two points so as to create a useably accurate scale. Not just a single point cal that shifts its totally inaccurate scale around.
