4/5 stars
Excellent app for audio enthusiast

This is my first review and I give it a 4 stars because it does what it say and I was impressed by how versatile the simple audio analysis can be with the power of an iPhone. I tested a Bose hooked to a Yamaha and the response was nearly flat. I tested another two hookups and they were all spikey, and now I know which parameters I have to tune (visually). Thank you! What I would like maybe is a bit more of resolution and control over the tests.
