dB Decibel Meter - sound level measurement tool App Reviews

40 add

eating a lot of space

very space intensive, collects data with every measurement... why???

Running on iPhone 6

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.

Highly inaccurate

The a, b, c scales are completely off and are not consistent while measuring the exact same 1kHz tone.

Storage Eater

Actual size of the app is about 22mb but after using several times it becomes more than 150mb, why?

Professional App

This is a wonderful app with professional sound level meter. It is easy to use. I will keep it on my phone.

Quite useful

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.

helpful app

It helps me a lot. I like the simple interface and it runs well on my phone.

Excellent App and Support

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.


Cheap and useless because it do not have a graphic display.


Absolutely garbage I want a refund if I could give zero stars I would have at least 25-30 decibals off

like it

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.

Good looking, good help, accurate

I chose this app because of the big font used for the main display, the clean design and the calibration put in to the development. I like to use this app. No complaints. One feature request: consider adding support for rotation to landscape, as many people (musicians especially) prefer to work on devices in landscape. Not a deal breaker but it does make it a pain sometimes, particularly if the device is connected to other stuff and is difficult to rotate without unplugging everything.

Professional and very professional

How to describe this app? Professional! Highly recommend it, because it works exactly as it describes as a great sound level meter on the go. It is creative and easy to use. Want to know how much the volume? Just open the app and start it, you can easily get your answer. Thank you for the developer.

Inaccurate, dont waste your money

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.

Professional decibel measurement

This is a very convenient to carry professional measuring decibels. Anywhere decibel environments can I measure. The measurement accuracy of the data.


Is it possible for you guys to create a noise cancelling app.. that lets us create a quiet zone. By using sound waves of opposite phase value so that the sound signal generated can cancel the ambient noise. I can help you more with technicalities. But would love to see that idea put into reality. Anyway thanks

Useful app

This is a professional measuring decibel application. The unique design. Simple, easy to carry. I can be anywhere measuring decibel surroundings.

Very efficient and unencumbered tool

The app has nice design. I am working in a sound department I rely very heavily on this tool and never have been disappointed. It works quite accurately. Wonderful tool


This software can be a substitute for professional decibel measuring instruments. Beautiful design. Operation is very convenient. Measurement data is accurate.
