Reviews

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!

UI elements do not scale correctly on iPad

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

Horrible color scheme

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.

Big battery drain

Crash at 66.6db

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