Good app but

It’s a good app, good lay but unable to get support. Email to developer bounced and website offers no way of contacting the developer. I just wanted to know if the pro version allows you to save recordings and view them later. But not prepared to purchase if I can not contact the developer!

Fantastic audio analysis

I use the app (I happily paid for the full version) in churches and small live venues for basic ringing out (setting GEQ on the desk) of PA speakers and foldback monitors. I’ve also used it for the dB-A SPL measurement as unbiased data when there’s a dispute about something being too quiet or too loud. The app does simple audio analysis, and does it extremely well. It’s not a complex app to use, it does just what I need it to.

Great but needs tutorials

This is a really great app and in my experience it has been accurate plus or minus 1Hz. I found it hard to use at first since I had no previous audio knowledge and didn’t know what the different types of graphs were. Having tutorials that explained terms/windows/graphs would make it far more accessible.
