Solid app, no iffy permissions, works out of the box and doesn't represent cellphones as being a reliable tool. It would be nice to have an alternate set of descriptive levels that reflect OSHA and other worker safety guidelines, which are reducing exposure times at increasing noise levels, described in OSHA 1910.95(b)(2)
I was expecting ads with a free app, and while they're only slightly obtrusive, I found myself wanting for an ad-free paid version. The app itself works fine--I like the ability to switch between light and dark themes--although without a proper sound level reference, I'm not sure how accurate the results are. At the very least it's a good objective measure of relative sound levels. Any movement right near the microphone, or touching the phone itself, will throw off the results a bit.
Please put this on notification panel so I can know that someone is calling me from next room when I've headphones on or noise reduction earphones, it will be great if you guys can put it on the notification light, like if someone shouts the notification light turns red and I'll be alert. The would be really a great application of this app.This is why I gave it just 1 star so the developer reads it.
Don't know how to calibrate or how it works, but is awesome anyway. But I'd like to see a setting time-lapse still going, even after screen lock. Barely 5 star.
Tried other free apps like this and they where pretty much a waste of time. Been trying to sound proof a room and showed a drop in levels. And helped to show where to place sound deading materials. So i would recommend this app. Its free and works. Ads are ads but not in the way and not a pain.
This is really a useful app, and is designed to do what it's meant to do for a novice user. I truly wish that there had been smartphones with these apps back in the 1960's and 1970's, because I'll be 60 years old soon, & can't hear very well due to the times of that era, and would have loved to be able to see how bad I was damaging my hearing. Please read this young people, and believe what I'm trying to explain to you!!!
