Awesome app !!! I was considering buying a sound level meter to measure the noise of my motorcycle exhausts and horns... Many of the reviews mentioned that a simple app on your phone was more accurate, so I figured it was worth a try.....very happy with the way this works .....I also downloaded their digital compass and it's so much better than the last one that I tried it's hard to believe how much better it is... !!!

This is the only sound monitoring app I use on any phone. Others seem like they "adjust" to the level of sound, and even if I add noise they'll stay around 40-50db. This is the only one that doesn't seem to do that, and it will show me the peaks which seem to be quite accurate. This will definitely help protect you from hearing damage. Plus, the UI is the best I've seen; nice, basic, and easy to read quickly.

Wish they'd tell us what's in the updates. , I hate Blindly updating apps. Very nice little sound meter. Once I calibrated it to read 0 in a totally noise free atmosphere, it seems to work fairly well. It's not a super high tech sound meter, but for a quick reference of sound levels, it does the job very nicely. I like that you can pull a list of noise levels up for reference and it has a dark theme / skin. keep up the good work.

Exactly what I needed. For some online classes, I needed to check my background noise level. The sound level descriptions were much more meaningful for me than just numbers. The live graph was also helpful, to get a sense of how common noises might affect the audio too. I wanted to make sure I was respectful of others in the class, and now I have better confidence in that.

Trying to find a noise meter that worked every time, worked consistently & quickly was difficult, but here it is. Several of these utilities are good. The bad ones outnumber the good. Then there's the group this app is in. Well, not sure if you can call it a 'group' since this one is sitting alone on top of the gold medal platform where the apps that out-perform all others are and ain't no one else very close! THANK YOU!

Seems fine. Has a graph and the actual number. Not sure how frequently it samples, seems 2 or 3 times a second. Nice description of the different sound levels. 60 decimal shows as normal conversation. I'm using it to check alarm clock volumes so far they're all 60-decibel; seems pretty low. Already returned two clocks as too quiet to disturb my slumber. Hope this one works better.
