Good app

Ive been a professional sound man for 30+ years Ive seen a lot of gadgets some work and some dont but if you need good ball park measurements this app is what you need. Ive tested it against my DBX RTA, Signal Scope and Mac the Scope on my lap top and its accurate if you calibrate it properly. Its a good app for spot checking a room before you set your system.
