Problem solved, great app

A great app when it was working. Now, running an iPhone SE 2020 with latest iOS no tracks show up in the app at all - not even music not bought through iTunes but from CDs I own.

Problem solved:
Sorry to be dumb; this app only recognizes tracks that are downloaded from iCloud to my actual iPhone - not tracks that are streaming from iCloud. This makes sense.

Overall great app

Great app for fine tuning sound in car audio or for extra sound boost on iPhone. If there's anything that I had to gripe about, it would be only two things. First.. no screen rotation. App should rotate when the phone is rotated, second.. the little blue dots used to make fine tuning eq adjustments can be frustrating for someone with wide thumbs, especially the ones on the edge of the screen. Besides that... worth the download. I have a Sony Xplode radio in my truck, which already has multiple sound adjustments, this app helps fine tune even further, ever track sounds amazing, from metal to country to rap, all sound perfect for my taste.

Sounds great

I use it daily when I Bluetooth my iPhone 10 to my BMW X5 SUV. My IPhone 10 pairs up fast and the Equalizer Pro APP is ready to go-I leave the app open. SOUNDS better than the proprietary music app that comes with IPhone 10’s operating system. You have to experiment and experience the nuances in this powerful app until you find your sweet spot. If you don’t like tinkering with apps just play Equalizer Pro as is...you will definitely enjoying it. It plays on my Denon receiver at home and the music coming out of my speakers sound rich and powerful.
