Pros and cons of dB Decibel Meter - sound level measurement tool app for iPhone and iPad

dB Decibel Meter - sound level measurement tool app good for

Seems to work very well. After testing, it picks up my alarm clock ticking noise which is about five feet away from the position of the phone. Short ticks are 36 DB and long tick is 37 DB. Seems about right to me.
This is a wonderful app with professional sound level meter. It is easy to use. I will keep it on my phone.
I gotta say this app is quite useful. The db measurement is really accurate. Plus, the UI style of this app is really great, the developers taste is quite good. And I have recommended this app to some of my friends, so far they all like it. Nice job developers.
It helps me a lot. I like the simple interface and it runs well on my phone.
Precision decibel meter, i use it often to measure the noise level in my rooms and surroundings to get a sense, for normal day to day use, i highly recommend this one.
I have been practising the piano.I dont mind the noise during the day.But I need this application,It might help to lower the volume.

Some bad moments

very space intensive, collects data with every measurement... why???
The a, b, c scales are completely off and are not consistent while measuring the exact same 1kHz tone.
Actual size of the app is about 22mb but after using several times it becomes more than 150mb, why?
Absolutely garbage I want a refund if I could give zero stars I would have at least 25-30 decibals off
I downloaded this to use with one of my students who is working on controlling her vocal volume. In a completely silent room, the app read 70 db. Its a piece of junk. Dont waste your money.
This is a professional measuring decibel application. The unique design. Simple, easy to carry. I can be anywhere measuring decibel surroundings.
