Essential, but AutoEQ has been long broken
I am an Origin Acoustics dealer and most of my customers have iPhones and all who have tried this app have reported this crash.
I’ve been bringing an old Android tablet to do calibration when I install Deep subwoofers and I have been having to qualify sales of those subs to customers that the advertised calibration features does it work unless running Android.
I expect better, and so do my customers.
