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. Show more

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!

I've found that UI elements do not scale correctly on iPad such as "74.5" would show up as "74..." for the peak dB value. This makes it unusable on iPad.

I have loved this app previously. In fact, I would have always given this app five stars until this version. I have been using this app for years now and I have always used the 'dark metal' color scheme. Now the only option is white. The white color option is TERRIBLE!!!!! As a foh guy, I use this app a lot. But I think I will be looking for another app because the white color scheme adds extra light to foh and the white is extremely harsh on the eyes. If you have not updated to the newest version, don't. It's not worth it. Show more

Big battery drain

Like the title says this app apparently likes heavy metal or satan or both. It has crashed several times frozen on 66.6db. m/

I install professional audio and run sound at various events and I've been using this app for over a year with great success. The readings are very accurate and the app is easy to use. I'm glad this app came out because it is easy to check SPL on the fly without carrying a meter around with me everywhere I go. However, since the latest version came out, it has been crashing my phone every time I use it. It freezes, and my phone becomes completely unresponsive. I cannot even reboot. I would have gave it 5 stars except for this problem. Please fix this app because I use it almost weekly. Thanks. Show more

Perfectly

My only wish: I'd love to have the analog-style UI from their $.99 younger brother SPL Meter.

Best db meter on for iPhone. I've downloaded and used them all. This one is easy to use, has the most parameter settings, and the ability to record peaks. It is however, strictly a db meter. Some other meters show frequency and plots of readings over time. These would be nice features to see added. Ther one feature I think is clearly missing is the ability to utilize the capabilities of the iPhone to actually transmit the captured data. If this were coupled by the ability to record real time readings this would be an awesome application. Having spectral analysis, and perhaps capture, would make it perfect. Show more

It's amazing that anyone gives this application anything less than a stellar review. It does what it's supposed to do, does it well and reasonably accurately. It is preposterously inexpensive. And it's always here, on my phone, ready to use whenever I need it. I do wish that the reviews were flagged and votes not counted when people simply can't figure out how to use it or don't like the way it looks. It renders the "5 star" voting approach meaningless for those of us who are looking for tools that work. It's a tool, not a toy or a game. Show more

I wish people would write reviews within the context of the App. This is an SPL meter that works on you phone. IE a reference tool when you're caught without your pro gear. And as such it works very well. Also, there's a reason for a 105 db threshold on your iPhone. Someone is holding a phone to their ear as you transmit a +db signal. Granted I'm sure no phone manufacturer would knowingly create a reciever that would reach beyond pain and damage thresholds. C'mon people think! Show more

I agree with review 4 very nice software you have your phone with you all the time but not your audio tool box or ivie or other professional tools But you do have your phone John Show more

The new appearance hurts my eyes. Please let me downgrade!

I'm not sure if I'm using it rite or if it's accurate but it's fun to mess with and I was wondering what's the max reading on this thing everything I've tried it on came to 107.6db can it go higher?? Show more

I compared it to a SPL from Radioshack and it does not even come close to being accurate. Specifically for tuning subwoofers it is off by 25db.

Great app, really easy to use and quite accurate without additional calibration. Compared it to Radio Shack SPL meter and they are both very close.
