Very straightforward to use, and great, use able features. I've just downloaded it and don't have an opportunity to calibrate it at this point, however found it immediately useful for doing relative noise surveys of our meeting rooms at work. Obviously the response and pickup pattern of the phone's mic will impact the validity of any calibration, especially for octave and third octave band SPLs. For more critical applications an actual measurement grade omnidirectional mic could be connected, or just get a "proper bought one" measurement system, but for cheap and cheerful this is a terrific little app.
Nice app! All business and no distractions. Very accurate when calibrated. It's a keeper.
Great (& free!) measuring tool. Thanks.
Doesn't do the one job it's supposed to. Measure SPL. It clocks in at double what every other app does. 80db in a quiet room?
The best, most comprehensive SPL meter app available.
