The app worked like a charm on my iPad. In fact I felt it easier. I just plugged in my room dimensions to find my Schroeder frequency for my room, let Audyssey donits thing like always then made my alterations. Not EQing the full spectrum has done wonders in my room. The Audyssey Ref and Flat setting in my AVR’s have either sounded too dull or too sterile. Limiting MultiEQ to 300hz has brought new life to my speakers.
