Decibel Meter Pro is full of features sound level meter with exclusive accuracy of measurements and integrated Spectrum Analyzer. Calibrated with professional dB meter.
The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?
dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters.
(Please note that dB Meter Pro app is not a replacement for professional devices and should be used for personal purposes only.)

Love this app works very good
Developer Response ,
Thank you for your positive feedback and support! I hope you continue using and enjoying Decibel. 😊
It’s not free
Hate when I’m being scammed! It has a 7 days free trial, but that’s not like being for free! Stop scamming.
Btw: it worked ok, the one time I used it!
Developer Response ,
Thank you for sharing your feedback on using the Decibel app. I am sorry your experience was not fully positive and would like to clarify any misunderstandings that may have led to this. Decibel has a free version designed for casual users and a Pro version with more complex features for Pro users. If you do not need any of the complex features and want to use it as a simple utility tool, I recommend you use the free version by simply skipping the free trial/subscription pop-up that appears when you first open the app by closing the pop-up window (use the X in the upper corner of the screen). I hope my reply helps clarify any misunderstandings and you continue to use and enjoy Decibel. Wish you all the best!
Work’s fine 👍
It’s an ok app
