Thank you for this app. I was looking for something that could give me a general idea of the sound dB ranges in different locations. Since I only needed a general range for this project I looked for a free or low cost app. It worked better than I expected a phone app would be able to. I felt the need to leave a review as I am surprised at the amount of people that left negative reviews. The iPhone mic is quite different than a calibrated device that cost $100 and up. Not to mention variances in cases, dirt build up, people’s hand placement, even the direction the mic is being pointed at could slightly alter results. All that said this was accurate within 5db up or down in my results. Considering all I mentioned above that is pretty good. If you need something highly accurate for something of importance you should be looking into an calibrated device made for such things.

I purchased the pro version as I am an audio engineer and would like to have something convenient as a quick reference rather then pulling out my larger, more professional tools. So far this has been pretty accurate and quite helpful. I would like to see some adjustability on the “over limit” marker. There are times I am given a dB limit to follow and being able to set this for when the meter reaches “over” would be nice. Maybe even some other larger notification and options to turn this on and off? A couple tweeks and this app would be amazing! Solid product for sure!

Despite claim that it is calibrated with a professional sound level meter, I found the measurements to be consistently 5-7 dB higher than my trusted B&K 2250. That is way higher than accepted error reported by standards and the main NIOSH hearing group study on smartphone apps accuracy. There aslo no documentations or papers to support the claim of accuracy. Another flaw: Peak level should never be lower than max level, yet in this app, it seems that Max is sometimes higher than Peak. Maximum sound levels are averaged over the time period it's measured at while Peak is the absolute highest level captured by the microphone before any averaging or RMS calculations. Finally, what is the average displayed? Averaged based on what criteria? Most sound level measuring instruments have a threshold value as specified by a threshold level and an exchange rate, yet this app does not provide any such information. A calculated "average" is really useless without these parameters.

As my title says I don’t believe the app is inaccurate, I think it’s the devices. Obviously iPhones weren’t developed to be accurate measuring tools. Just think about how your voice sounds when you record it through the phone onto something like GarageBand? It sounds like dog poo, so yeah, that’s what the app has to work with. Based on the fact that the measurements are done with a mic diaphragm the size of a BB I think it does a great job. I do wish they would tell everyone these things though so people aren’t disappointed, thus the 4 stars. I know it should be totally obvious it’s a freakin app on a phone, but people seem to think they should get Lamborghini performance out of there Camry.....

The basic dB meter itself seems to work okay but isn’t going to tell you much more than your own ears can likely figure out. I was hoping to be able to detect very high pitched sounds but that doesn’t seem to happen. The worst part though is the pop-ups to purchase the several different pro versions. If you press the home button to back out of it with a phone that confirms purchases with your finger print, you end up paying for whatever “pro” version pop-up they are showing... and there are seemingly endless “pro” options. This feels very deliberate and appears to be a scam. I ended up with a $10 purchase I had no intention of making and still get prompted non-stop for more purchases! Avoid this app!!!!
