Sound Meter is an excellent sound meter. It matches the NIOSH app for the iPhone exactly, which says a lot. It met all my requirements, including an excellent graph showing the average SPL exposure in DBs, and the displayed values are very easy to read. Kudos to the developers for such a high-quality app! My only ask is that you add color segments on the arc of the readout meter, indicating danger level (e.g.: red for >= 115q db).

I'm only had this app for a very short while, but in the brief time that I've had with it, the level of polish, the beautiful UI and the consistent and predictable results have been impressive, and a testament to the obvious love and skill that went into the development of this application. Should anything change I'll update , but as of now I consider this beautiful app to be flawless .

About as good as these things can possibly be on a random phone microphone. You can somewhat accurately measure consistent noises like your fridge but anything else is going be off. You need to have a consistent microphone for these to work very well, it is impossible to calibrate for every microphone a phone could have.
