Good app – RTA Review

I've been a professional sound man for 30+ years I've seen a lot of gadgets some work and some don't but if you need good ball park measurements this app is what you need. I've tested it against my DBX RTA, Signal Scope and Mac the Scope on my lap top and it's accurate if you calibrate it properly. It's a good app for spot checking a room before you set your system.
