Looks like it probably works good once you get to the actual meter. The app asks for setup Info every time you open it language, etc.. then 3 pages of adds to trick you into downloading more apps. Then once you finally get to the meat of it, the meter is nice and big but the controls are icons that don't make sense to me. Stop/start the meter and you get another add, somehow i downloaded Majong. It takes 2 minutes any time you want to use it. Way too much hassle.

This would be helpful but there are WAY too many ads!! When I need it, I need to be able to open the sound meter quickly to catch the noise. This app requires so many ads that by the time I get to the meter the noise has passed. Or I'll be recording the sound and will suddenly be thrown into an ad. Not helpful! I can't use this app with all the ads in the way.

so many ads that it's difficult to use. previously it was annoying, but you could use it after watching an ad. now, it's just a fancy app to load ads. you'll wait 30-60 seconds in the screen showing the ad even after it finished and wondering when you get to use the actual app... but you're never given the choice. horrible. find another app.
