I have been using this app for over a year and through several updates. It has always worked well and accurately. It has been a useful tool for monitoring the noise exposure and deciding where and when I need to wear earplugs. The only feature it lacks (in my opinion) is the ability to run as a background process with the phone asleep (similar to the way you can play music), which would allow to have the screen off and use less battery when monitoring for long periods of time. Aside from that personal preference, this app has been reliable and helpful. I would highly recommend it.
No ads, no in-app purchases, no hassle to upgrade every 10 seconds, fully-featured unlike the other top apps that entice you with a single feature but force you buy an upgrade to get the rest of the functionality of the app. Developed for professional users who are serious about acoustics by the top hearing lab in the country, if not the world. I use a Larson-Davis 831 for my daily work and have compared many apps to my SLM and though I was always skeptical about apps, this one is the most accurate out there.
The app developers really deserve praise for creating a completely free app that doesn’t blast me with ads, beg me to upgrade, and generally distract me with BS when I try to use it. The interface is clean and easy to navigate. It seems very accurate, especially for what I need which is basically just comparing noise levels relative to one another. It never glitches or quits unexpectedly. I’ll stay loyal to this app, it is exactly what I needed.
I download this app and within 15 minutes it was for using it and fully understanding I had a couple of tech-support questions I emailed the company in Netherlands I believe and they answered within a day and they answered more than satisfactory with links and pictures and graphics. The application, the developers, and the tech-support are WONDERFUL!!! I can’t recommend this more highly — it’s the best dB sound meter that I have used. As I understand it if you buy one of the external microphones with your calibrated to the app and then you calibrate the dB Meter following their procedures, the results are legal, and from what I understand, admissible in court or other type of legal proceedings. Please don’t quote me on that part, but that’s my understanding. Thank you! Phil, Colorado
