Apps color scheme is unreadable
The color scheme/UI is gray all over even after resetting all settings and relaunching the app. There is no control in settings to change this. The app does not look like the screenshots.
Accurate and Easy to use
Once calibrated correctly this SPL meter is easy to use and accurate, worth every dollar!
Amazing
Oh no! A disastrous update!!!
They finally took the horrible, battery-draining background operation so-call "feature" out of RTA, but they put it into SPL. Now, when you exit this app in the conventional way, it keeps running and draining your battery!!!
Why they think this is a good idea or should be the default operation is just beyond me. Please, please, make this behavior optional and default it to operate in the way that most iPhone apps do, to exit the app when you press the home button.
------ original review -------
I have recently had the opportunity to compare with a very calibrated instrument and was very favorably impressed. This thing works very well.
I also checked my Radio Shack meter at the same time and it's good right around 1KHz which is where -- if you read its instructions -- it is calibrated. The Radio Shack SPL meter, by the way, while a bargain for the price and quite good for what it is, is not a good tool for tuning subwoofers at all. This iPhone ap, while better, still isn't the best for subs either with the built-in mic, but worked much better with an external.
Also, this ap's A-weight filter is better than Radio Shack's.
In conclusion, this ap is a bargain for the price and so handy to have with you.
A+.
My one suggested improvement: a logging mode which logs SPL at selectable intervals -- minutes and seconds -- and then can e-mail the log out in csv format with time and SPL reading.

Excellent
I tried a few similar apps before trying this one, and found it the best so far. Many options, and accurate settings.
Enthusiastically recommended
After accidentally losing the calibration of my subwoofer, I discovered that my trusty Radio Shack SPL meter was no longer accurate with sub-100-Hz test tones. I bought SPL and found it agreed stably within 1 dB of my main channel measurements using the old hardware and wideband pink noise. This is more than enough to validate it as a replacement for the RS meter, while it is a lot more cost-effective -- I spent the same amount today on a 9-V battery for the meter as the app cost!
